Solved: The pulley has a radius of 3 in. and fits loosely
Chapter 8, Problem 8-121(choose chapter or problem)
The pulley has a radius of 3 in. and fits loosely on the 0.5-in.-diameter shaft. If the loadings acting on the belt cause the pulley to rotate with constant angular velocity, determine the frictional force between the shaft and the pulley and compute the coefficient of kinetic friction. Neglect the weight of the pulley.
