Pаula H. Roy, plaintiff-appellee, then a seventeen year old girl, received severe injuries to her hand while inspecting electroplating finished work at Advanced Materials Systems, Inc. (AMS), third-party defendant. The machine which caused the injury, a take-up unit which had two motor-driven pinch rolls and a spool at the opposite end, was manufactured by defendant-appellant, Star Chopper Company, Inc., to specifications provided by AMS. The machine was designed to allow continuous electroplating, at a constant speed, of aluminum and other metal. AMS, through its then Vice President Hingorany, contacted one Michael Ca-bassa to design a machine capable of perfоrming the desired functions. Cabassa did the engineering drawings for the job, which included pinch rollers, and recommended that Star Chopper manufacture the machine. A draftsman from Star Chopper prepared more detailed drawings. No safety guards were provided in the drawings nor discussed by anyone. There was no warning on the machine of the dangers presented by the pinch rollers.
Plaintiff’s hand required eleven operations; extensive surgical repair was performed to attempt to reconstruct the hand. Even following surgery, her hand retains only 5% of its functioning ability and is severely deformed. Plaintiff received benefits under the Massachusetts Workmen’s Compensation Act for her injury. She brought suit against defendant manufacturer, Stаr Chopper, originally on three counts: negligence, warranty, and strict liability. She dropped the negligence count prior to the charge to the jury and dropped the warranty count after the jury returned a verdict in her favor of $848,000 based on strict liability.
Defendant brought a third-party action against Advanced Materials Systems, Inc., and its president, Ashok Hingorany for contribution and indemnity. The court dismissed the count for contribution and non-contractural indemnity; the jury found against Star Chopper on the implied indemnity count. Star Chopper now brings this appeal, asserting sundry errors by the district court.
CONFLICTS QUESTION
Star Chopper complains of the court’s choice of law rulings, both in the case in chief and in the third-party complaint. Under the rule enunciated in
Klaxon Co. v. Stentor Co.,
“(1) Predictability of results.
(2) Maintenance of interstate and international order.
(3) Simplification of the judicial task.
(4) Advancement of the forum’s governmental interests.
(5) Application of the better rule of law.”

Case In Chief
The district court concluded that, since Massachusetts was the site of the injury and the residence of the plaintiff and since Rhode Island was the state of incorporation of the defendant manufacturer, its place of
*1129
business and the locus of the alleged tor-tious conduct, sufficient minimum contacts existed for constitutional application of either state’s law. The court then analyzed each state’s laws relating to the principal action and found that a true conflict existed, Rhode Island applies strict liability,
Ritter v. Narragansett Electric Co.,
The trial court then applied the Woodward criteria and selected Rhode Island law. We now review the in-depth analysis by the district court of the Woodward factors.
(1) It is reasonable to assume that the defendant manufacturer, a Rhode Island corporation, would have purchased insurance commensurate with its potential liability under the Rhode Island strict liability rule. It was foreseeable that the corporation would be placed at risk for its manufacture of products and, as a corporation doing business in Rhode Island, would reasonably guide its actions by the liability imposed under Rhode Island law. Thus, its expectations would not be unfairly overturned by application of the Rhode Island strict liability rule. It is highly unlikely that the defendant would manufacture one set of machinery designed for use in Rhode Island and those states subscribing to strict liability and another separate set destined for states such as Massachusetts where strict liability has not yet been adopted. Predictability of result suggests the appropriateness of applying the Rhode Island rule.
(2) Interstate order is served when application of one state’s law offends no law or policy of the other state.
Turcotte v. Ford Motor Co.,
(3) The court felt that the judicial task would be neither more nor less simplified by application of either state’s rule. We cannot find error in this conclusion.
(4) Rhode Island, the forum state, has expressed interest in holding manufacturers of defective products to a standard of strict liability.
Ritter v. Narragansett Electric Co., supra,
(5) Rhode Island has stated clearly that it adopted strict liability because it views that rule as the preferable standard to which manufacturers of defective products should be held.
Id.
at 261-263.
See also Turcotte, supra,
[T]he justificatiоn for the strict liability has been said to be that the seller, by marketing his product for use and consumption, has undertaken and assumed a special responsibility toward any member of the consuming public who may be injured by it; that the public has the right to and does expect, in the case of products which it needs and for which it is forced to rely upon the seller, that reputable sellers will stand behind their goods; that public policy demands that the burden of accidental injuries caused by products intended for consumption be placed upon those who market them, and be treated as a cost of production against which liability insurance can be obtained; and that the consumer of such products is entitled to the mаximum of protection at the hands of someone, and the proper persons to afford it are those who market the products.
Restatement (Second) of Torts § 402A, Comment c. The district court properly determined that Rhode Island’s strong public policy in favor of strict liability represented that state’s view of strict liability as the better rule of law.
A balancing of the above factors permits the conclusion that a Rhode Island state court would have applied its own substantive law with respect to the case in chief on the question of strict liability. The district court sifted the various considerations and so concluded. We find no error.
Third-Party Complaint
Defendant claims that the trial court erred in applying Massachusetts law in the third-party complaint on the question of contribution from the president (Hingora-ny) of the third-party defendant corporation (AMS) and on the question of noncon-tractual indemnity 3 from both third-party defendants.
Under both Massachusetts and Rhode Island law, there can be no contribution from the employer, AMS, because of the immunity conferred by the workmen’s compensation statutes.
Liberty Mutual Insurance Co. v. Westerlind,
Mass.,
In Rhode Island, an employee has no immunity from suit by a fellow employee for employment related injuries.
Colarusso v. Mills,
Star Chopper raises the peripheral question of whether Ashok Hingorany, a corporate officer, should be allowed to avail himself of fellow employee immunity. The trial court found no Massachusetts case dealing specifically with the question, but reasoned that, since even states which do not recognize fellow employee immunity do grant corporate officers acting within their official capacity immunity, it was proper to assume that Massachusetts, with its more libеral stance toward employment related immunities would similarly immunize third-party defendant Hingorany. 4 Hingorany submitted an affidavit to accompany his motion to dismiss the third-party complaint as to him in which he averred that he was an employee of AMS. This was not contested or contradicted in any pretrial material. The court could, thereupon, accept as uncontroverted Hingorany’s statement that he was an employee of AMS and, therefore, entitled to fellow employee immunity.
Star Chopper sought indemnity, both contractual and noncontractual, from the third-party defendants. The district court applied Massachusetts law to the non-contractual indemnity question.
5
The court recognized the brоad immunity conferred by the Massachusetts immunity law and concluded that it extended to claims based on noncontractual indemnity as well as con
*1132
tribution.
6
After the district court rendered its decision, the Massachusetts Supreme Judicial Court addressed this specific question and answered it as did the trial court here: any claim for indemnity must rest solely in contract, either implied or express.
Liberty Mut. Ins. Co. v. Wester-lind,
Mass.,
The trial court correctly concluded that Massachusetts immunity would not bar the contractual indemnity claims, see id. at 959, and applied Rhode Island substantive law to the question of whether an implied contract to indemnity existed. Star Chopper misreads the district court’s rulings when it complains that the court did not apply Rhode Island’s liberal indemnity law on this question. The court reasoned that the policies underlying strict liability would be best served by retaining in full the liability of the manufacturer for its defective manufacture of a dangerous product, but then permitting it to seek indemnity from the purchaser for failure to add a safety device should the jury find that the purchaser impliedly contracted with the manufacturer to do so. Star Chopper did receive the benefit of Rhode Island’s substantive indemnity law on the issue of implied contractual indemnity.
JURY CHARGE
Defendant claims that the court erred in charging the jury on the applicable law. Initially, we acknowledge plaintiff’s argument that defendant waived many of its objections by failing to comply with Rule 51 of the Federal Rules of. Civil Procedure:
No pаrty may assign as error the giving or the failure to give an instruction unless he objects thereto before the jury retires to consider its verdict, stating distinctly the matter to which he objects and the grounds of his objection.
Compliance with this rule has been held to be important to the “orderly and just functioning of the judicial system[.]”
Morris v. Travisono,
*1133
The objections defendant made following the trial judge’s charge to the jury were covered under a blanket exception to the court’s reliance on Rhode Island law (presumably the strict liability imposed by Rhode Island, although not even this.point is clearly articulated) rather than Massachusetts law.
8
We dealt extensively with the choice of law question above. For our purposes here, we note that this generalized objection does not sufficiently raise on appeal the issues dеfendant herein attempts to present.
Morris
v.
Travisono, supra,
We now turn to those sections of the jury charge to which Star Chopper did make timely objections and which it alleges were erroneous.
Star Chopper claims that the court should have instructed the jury on comparative negligence, even though the action went to the jury without a negligence count. Comment n to section 402A of the Restatement (Second) of Torts addresses the issue of whether contributory negligence is a defense to a strict liability action and concludes that it is not. The Comment goes on to explain that the defense of assumption of the risk, however, is available. Star Chopper attempts to avail itself of this distinction, suggesting that Rhode Island’s comparative negligence law overlaps somewhat with the defense of assumption of the risk. This argument is without merit. The Rhode Island Supreme Court specifically re-
*1134
jected this position,

Kennedy
v.
Providence Hockey Club, Inc.,
Star Chopper objected to the district court’s failure to instruct the jury that, as a manufacturer of a component part, 12 it could not be held liable. The law is clear that a manufacturer of a component part can be held liable under strict liability. “There is no dispute that the strict liability applies to the manufacturer of the product, including the maker of a component part. . ” Prosser, Law of Torts, supra, at 664. See also 1 Frumer and Friedman, Products Liability § 9.01, at 188.1-189 (1978).
Following the jury charge, Star Chopper objected to the court’s use of the phrase “convinced by a fair prepounderance [sic] of the evidence” rather than “persuaded” when ■ discussing the burden of proof Star Chopper carried on its affirmative defenses. Before us, it attempts to question the propriety of placing upon Star Choppеr the burden of proof at all on these issues. Since this was not objected to at the trial below, see discussion supra, it is not properly before us. Fed.R.Civ.P. 51. Restricting our review to the court’s language, we find no error in the court’s phraseology.
OTHER ISSUES
We find neither abuse of discretion nor reversible error in the court’s evidentiary rulings, cited by defendant for review by us. Briefly, we see no abuse of discretion in the following: admitting projections of plaintiff’s loss of future earning power; refusing to admit evidence of post-accident repairs to the machine, Fed.R.Evid. 407; permitting extensive cross-examination of witness Cabassa concerning the whereabouts of long-absent blueprints,
Hobart v. O’Brien,
We do not find persuasive defendant’s allegation that the trial court should be reversed for refusing to join as an indispensable party the plaintiff’s workmen’s compensation insurance carrier as the real party in interest.
See
Fed.R.Civ.P. 17(a) and 19(a), (b). Plaintiff entered into an agreement with the insurance carrier to reimburse the carrier out of any possible recovery for amounts paid pursuant to the workmen’s compensation program and the insurance carrier expressly waived its right
*1135
to sue defendant. There is, therefore, no danger that defendant will be subjected to “double, multiple, or otherwise inconsistent obligations,” Fed.R.Civ.P. 19(a), by failure to join the carrier as a party plaintiff.
See Provident Tradesmens Bank & Trust Co.
v.
Patterson,
Star Chopper argues that the court erred in failing to declare a mistrial or grant a motion for a new trial after plaintiff’s attorney adverted to the fact that defendant carried insurance. The reference to insurance was made during an extensive colloquy concerning the existence of blueprints for the defective machine and was entered while counsel was reading from a pretrial interrogatory.
And question 67 was, “Does Star Chopper, its attorneys, its insurance carrier or anyone acting in its behalf have or know of any photographs, motion pictures, maps, drawings, diagrams, measurements, surveys or other descriptions concerning either the scene of the accident or the take-up unit as referred to in interrogatory numbered 3406 and if so state (a) its nature, (b) its subject matter, specific subject matter and (c) the date it was made or taken and (d) the name and address of the person making it or taking it and the name of such person’s employer, (e) what such item purports to show, illustrate or represent, and (f) name and address of person having custody of such items,” and did you not answer under oath “67. The defendant has various photographs which it will produce upon request,” was that your answer, sir?
This one reference was adjudged inadvertent by the trial court and not prejudicial. We agree. Following the colloquy quoted above, counsel continued his intensive questioning of the witness as to the blueprints; counsel did not draw attention in any way to the existence of insurance. We do not view a single, unrepeated reference to defendant’s insurance carrier, entered inadvertently, in a trial which lasted three weeks, so inherently prejudicial that failure to declare a mistrial constitutes error.
Compare Cochran
v.
Dube,
Defendant asks us to declare the Rhode Island statute, permitting accrual of interest from the date of the cause of action, to be unconstitutional. R.I.G.L.1956 (1959 Reenactment) § 9-21-10, as amended by P.L.1977, ch. 10. Star Chopper asserts that the mandatory language of the prejudgment interest statute,
i. e.,
interest from the date of the cause of action “shall be included,” deprives defendant of its property without due process and denies it equal protection of the laws. It argues that a defendant is prejudiced by the mandatory language in those instances where dilatory tactics of the plaintiff have caused delay in going to trial. A federal court should properly apply a forum state’s pre-judgment interest statute when sitting in a diversity case.
Massachusetts Benefit Association v. Miles,
Star Chopper’s allegations that the verdict was incomplete and that it was coerced do not withstand analysis. The jury returned a verdict in favor of the plaintiff on the issue of strict liability; it left unanswered the court’s interrogatory on the warranty claim. This does not render the verdict incomplete since plaintiff thereupon withdrew the warranty count. The court had instructed the jury that plaintiff could recover on either strict liability count or the warranty count and the jury clearly found for her on the strict liability claim. There is no fatal inconsistency between permitting a recovery under strict liability and failing to render a verdict on the warranty count.
See Kissell v. Westinghouse Electric Corp., Elevator Div.,
Star Chopper claims that the hesitation of juror Carnevale indicates that the verdict was coerced. The court polled the jury with respect to the third-party claim. When juror Carnevale was asked whether it was her verdict that judgment should be for third-party defendant AMS, the following colloquy took place:
The Clerk: Mrs. Carnevale—
Juror Carnevale: Could I ask, I need help. I think. I’d like to ask someone a question, I don’t know who to ask.
The Court: That’s not the point, Madam; the point is this is your verdict sheet. The question is when you voted, “Do you find for Star Chopper Company, Inc. or Advanced Materials System, Inc.?” all right—
Juror Carnevale: Advanced Materials Systems.
The Court: Is that clear enough to you?
Juror Carnevale: Yes, your Honor.
The Court: All right.
The Clerk: Do you find for Star Chopper Company, Inc. or Advanced Materials Systems, Inc.?
Juror Carnevale: Advanced Materials Systems.
The trial judge hаndled the matter properly. It is the court’s function to determine solely whether the verdict represents the juror’s position; the court should not inquire into the reasoning process or motivation behind the verdict.
See Grace Lines, Inc. v. Motley,
Proceeding to another of defendant’s claims, we hold that the court properly granted in part third-party defendants’ motion for summary judgment. As discussed supra in the section of this opinion dealing with choice of law, the court correctly ruled that, under Massachusetts law, neither third-party defendant could be held liable for contribution or noncontractual indemnity to Star Chopper. The court, having concluded this, properly granted summary judgment on those issues in favor of third-party defendants.
Defendant has not met the burden for a showing that the court abused its discretion in failing to grant a new trial. Defendant’s arguments incorrectly perceive the law of strict liability and otherwise fail to show any trial error sufficient to require us to override the district court’s refusal to grant a new trial. We have considered all other points raised before us by Star Chopper and find no merit in any of them.
Judgment affirmed.
Notes
. Defendant urges on appeal that the court erroneously selected Rhode Island’s pure comparative nеgligence over the Massachusetts rule which excludes recovery where plaintiffs negligence exceeds that of defendant by even 1%. No charge was given by the court relative to comparative negligence; the case went to the jury without a count based on negligence.
. Defendant neither does business regularly in Massachusetts nor employs any people there.
. Noncontractual indemnity, unlike contribution, permits one tortfeasor to recover the entire amount of any recovery from the co-tort-feasor. Indemnity can be provided to avoid an unjust result (e. g., where an employer is vicariously liable for the wrongdoing of an employee); where one tortfeasor is primarily liable and the other one secondarily liable; where one party has been merely negligent and the other intentionally or recklessly wrongful; where one tortfeasor has been “passively” negligent and the other “actively” negligent. See generally W. Prosser, Law of Torts § 51 “Indemnity” at 310-313 (4th ed. 1971); Leflar, Contribution and Indemnity Between Tortfeasors, 81 U.Pa.L. Rev. 130 (1932).
. One commentator has said that, since corporate officers “are treated as co-employees in states that make co-employees liable, it is only logical that they should be treated as co-employees in states that make co-employees immune.” 2A Larson’s Workmen’s Compensation Law § 72.20 at 14-44 (1976).
. It is unclear whether a true conflict exists between Massachusetts and Rhode Island on this question. The Massachusetts rule, is that no claim for nonсontractual indemnity will lie in an action against an employer. The Rhode Island rule, though not as clearly enunciated, appears to be the same. The Rhode Island Supreme Court has held that, by enacting the workmen’s compensation act, the legislature intended to exclude any common law right of action an injured employee might otherwise have against the employer.
Cacchillo v. H. Leach Machinery Co., supra,
. “As in the case of contribution, [noncontrac-tual] indemnity is not allowed against one who has a defense, such as immunity, against the original plaintiff.” W. Prosser,
Law of Torts
at 313 n. 12 (4th ed. 1971) (citation omitted).
See also Newport Air Park, Inc. v. United States,
. The court’s chargе included the following: [T]he law considers that a product is in a condition of defectiveness or contains a defect if, upon weighing the ease and feasibility of construction of a safety device against the magnitude of threatened harm in not constructing such a device, it is determined that the latter is of great magnitude and the former is relatively inconsequential.
A manufacturer must give adequate warning of the existing danger, and a product sold without such warning is defective, whenever the manufacturer has reason to anticipate that danger may result from a particular use. The warning must be given in a manner that gives reasonable assurance that the information will reach those whose safety depends uрon their hearing it. But a seller is not required to warn where the danger or potentiality for danger is generally known or recognized.
In other words, if you decide that the danger or potentiality of danger is generally known or recognized by those who the defendant could reasonably anticipate would come into contact with the machine, no specific warning was required to be given by the defendant of the danger. But if you decide that the manufacturer defendant did have reason to anticipate the danger and that the *1133 danger was not so obvious as to eliminate the manufacturer’s responsibility, the failure to give adequate warning may make the machine unreasonably dangerous.
Star Chopper rаised certain affirmative defenses on which the court instructed the jury. The court’s charge regarding the defense of assumption of the risk was:
[T]he defendant is saying a dangerous situation existed; that the dangerous situation was obvious or that the plaintiff knew of the dangerous situation; and that with this knowledge, she voluntarily exposed herself to the danger and was injured thereby. Now, ladies and gentlemen, if you find that the defendant has established these facts by a fair preponderance of the evidence, then your verdict must be for Star Chopper. I add this is what we term an affirmative defense and the burden is on the defendant to prove such allegation by the fair preponderance rule. However, in weighing this standard, I instruct you that, “The standard to be applied is a subjective one, of what the particular plaintiff — here we mean Paula Roy — in fact sees, knows, understands and appreciates.” If by reason of age, or lack of information, experience, intelligence or judgment, Paula Roy did not understand the risk at the time of the accident, then she did not assume the risk and cannot be denied recovery on this ground.
The court’s instruction on the affirmative defense of lack of feasibility stated:
Star Chopper has raised another defense that you must consider. If it was not feasible at the time of manufacture for Star Chopper to install reasonably effective safety devices, Star Chopper is not liable to Miss Roy. You must be convinced by a preponderance of the evidence that Star Chopper did not know, and a manufacturer of similar machines with reasonable skill would not have known, enough about the functioning of the machine at Advanced Materials’ plant to enable the installation of reasonably effective safety devices. . . . You must find that Star Chopper made all reasonable efforts in light of the dangers of the machine to acquire that information. You should also consider whether Star Chopper could have installed reasonably effective devices, not necessarily the most effective devices. To prove that it was not feasible, Star Chopper also must show that there was no аll-purpose safety device available and that installation of any available device would make the machine unusable or unsafe for at least one of the purposes Advanced Materials was likely to pursue. . . . Even if Star Chopper had been told or expected that Advanced Materials, Miss Roy’s employer, would install safety devices, Star Chopper is nonetheless liable if it could have placed safety devices on the machine. Furthermore, even if it was not feasible for Star Chopper to install safety devices, the machine is still in a defective condition if Star Chopper failed to issue adequate warnings and Star Chopper would still be liable.
. Defendant’s objection to this portion of the charge was as follows: “I will take exception to the choice of law which the Court selected insofar as Rhode Island and Massachusetts law is concerned . .” Defendant did not specify in what manner the court’s rulings on strict liability were erroneous.
. Star Chopper states in its brief that Rhode Island has defined contributory negligence as overlapping the defense of assumption of the risk, citing
Richard v. H. P. Hood & Sons, Inc.,
. The court correctly ruled that the standard to be applied in adjudging the defense of assumption of the risk is a subjective one,
i. e.,
what this particular plaintiff saw, knew, understood, and appreciated.
Kennedy v. Providence Hockey Club, Inc.,
. For a discussion of the split in authority concerning the applicability of comparative negligence in strict liability cases see 2 Frumer and Friedman, Products Liability § 16A[5][g], at 3B-226 — 3B-230 (1978).
. There is considerable uncertainty whether Star Chopper correctly characterizes the machine which injured plaintiff as a “component part.” Trial testimony suggests that the take-up machine was a self-contained unit, not a component part. However, even under Star Chopper’s view of the take-up machine as a component part, strict liability can attach.
