The constant 10-lb force is applied to the 79-lb stepped cylinder as shown. The centroidal radius of gyration of the cylinder is 9.7 in., and it rolls on the incline without slipping. If the cylinder is at rest when the force is first applied, determine its angular velocity w at a time t = 6.8 sec later. The angular velocity is positive if counterclockwise, negative if clockwise. Assumer 7 in., R-11 in., 0-15°, P=10 lb. Answer: w- i 8.56 rad/sec
