Hello. Sorry if it is a bother, but i'm starting Applied Mechanics (statics) and my books states this "principle of transmissibility" with no proof (except for the one given in the dynamics volume which i don't have). could anyone provide me an explanation or point me in the direction of a website which explains where this comes from? my main problem with it is that, if you slide a force vector along a line which doesn't intersect the center of mass, you should get a different angular momentum... i probably didn't understand it. either way, it would be useful to see the proof. thank you in advance.
