I want to know how much force I am exerting on the top of a post with a chain hooked up to my truck. 2 Conditions: 1. With a running start of 15 feet, some impulse action happening here, (Assume chain is unbreakable) 2. Just at a steady pull with no running start, up until the wheels slip from overcoming friction. Given: - A Certain truck's specs; i.e. torque at a certain rpm, mass, 0-60 specs, etc. - Certain friction coefficient Did I miss anything? It's been a while since ENGR school.
