1. The problem statement, all variables and given/known data a wheel of mass M has a radius R It is standing vertically on the floor and we want to exert a horizontal force F at its axle so that it will climb a step against which it rests. The step has a height h where h<R what is the minimum force F needed? 2. Relevant equations torque = Ia torque = FR 3. The attempt at a solution Alrighty so i know that to solve this problem i will have to set the torque created by F equal to torque created by the weight of the wheel (Tf = Tw) and then solve for F but i honestly have no idea how to do this. There was another topic created for this problem but i could not follow what they did =\ https://www.physicsforums.com/showthread.php?t=30938 help please?
