Question(s) / Instruction(s):

A capstan is a rotating drum or cylinder over which a rope or cord slides to provide a great amplification of the rope's tension while keeping both ends free. Since the added tension in the rope is due to friction, the capstan generates thermal energy. If the difference in tension (T_0-T') between the two ends of the rope is 520 N and the capstan has a diameter of 10.0 cm and turns once in 0.90 seconds, find the rate P thermal at which thermal energy is being generated. Give a numerical answer, in watts, rounded to the nearest 10 W.
