[ Physics ] Open Question : Need help finding equation for torque?
I have a bike with a weight of five pounds tied to the rim. I use a torque wrench to turn the bolt at the center of the pedal (which turns the wheel). The resistance will always be a constant five pounds, so the distance turned is irrelevant. believe me, I actually got a torque wrench and tested it, and the torque stayed the same no matter how much it was turned. Basically, think of it as a screw that always had a five-pound resistance, and if it was held still, there would always be five pounds of force pulling it, so how much torque would be required to keep it from turning? (i need an equation to determine this. the answer is about 60 pound-inches.)
