PSI is the result of pound-foot force on a single inch of surface area, and a pound foot of force is equal to 1.3558179483314004 joules.Link in OoT threw a granite block weighing 1388.994 tons at a speed of over 75 meters per second, with relative ease. For this exercise, I'll be rounding these numbers down to 1300 and 75.
To accellerate a block that heavy to that speed Link had to generate 3316894205 joules of energy. Ganon is stronger than even OoT Link with the gauntlets, and TP Link sword locked with Ganon. [AHAH, relevance!]
Now let's assume that TP Link is as strong as OoT Link. [He's actually stronger.], and Ganon for whatever reason, rather than resisting Link in the sword lock, remains static, thus it's only the reaction of Link's own action on the palms of his hands when he sword locks with Ganon in TP.
This is; 2446415618 foot-pounds of force, now divide by the area of his hands. let's assume for the pure lulz that the palms of his hands combine into a square foot of area. Divide by 144 for PSI and you get 16988997 from just his own down-rounded strength, spread over an impossibly large surface area, and this amount of force did no harm whatsoever to Link.
FYI, thats 8494 tons of PSI.
Edit: I laugh at the idea of a bullet hurting him. |:
This is relevant becaause the entire equation shows OoT Link's own strength acting on himself, with no additional forces whatsoever, and rounded down to the point of ridiculousness.
