From what I understand, PSI is a measurment of force, PSI stands for Pounds Per Square Inch, so if a fighter can punch at 2000PSI does that mean in a punch from 1 square inch he can move a 2000 pound ( 907 KG ) object? Is this true? If not does someone know the correct mean for this?Thanks.
Aha! A trick physics questionThe answer is probably, but, you're asking about a 2-dimensional answer (a vector (or line from Point A to Point B)) using 1-dimentional information (you supply only PSI)The scientific answer is that not enough information is provided, you need to provide an element of time and frictionA child of 5 years old could move such an object with her pinky, given a frictionless surface upon which the object to be moved is resting, and the child is standing on cement or carpetThis object need not move far, but from a technical point, any distanct 0 means that the child moved the objectSound unreasonable? Guess again: Such is the principal upon which inventions like The Moving Men workYou are given 4 slippery plastic disks (the Moving Men) to place underneath the four legs of a couch to move over a carpetAny child could now move this couchA crane hoisting a 67,000lb loaded metal shipping container onto a flatbed truck could be maneuvered by a single human by hand, and with the precision of a few millimetersThat's because the suspended shipping container is not subject to any frictionYou didn't mention the manner of the object being movedIf by punching, then, the responant who says you'd break your wrist is probably rightWhile you may move the object by punching it, you will probably also break your wrist.
