The weight in Fig. 1 must be raised at the rate of 10 fps. Motor pulley is 9.25 in. in diameter, and turns 870 rpm. Length of the belt is 125 in. Expected life is 10,000 hr. Neglect fatigue effects at large pulley. Assume a service factor of 1.6 will care for impact effects and friction of the system. Find the center distance and the diameter of the large pulley.
