Solve Prob. 8-132 if the force P is applied horizontally to the right.
Prob. 8-132=The 5-kg pulley has a diameter of 240 mm and the axle has a diameter of 40 mm. If the coefficient of kinetic friction between the axle and the pulley is µk=0.15 determine the vertical force P on the rope required to lift the 80-kg block at constant velocity
