Question

A large reel of paper installed at the end of a paper machine. di = 2m, Tension on paper = 1000N. At to, J = 1000kgm² and the speed of Reel#1is 60rpm. Assume no loss. a. Calculate the motor power and torque at to. b. Suppose the paper was torn by an accident at to are and the reels are disconnected. The motor was running until it was tripped (motor torque = 0) after 1 sec. Calculate the speed of Reel#1 0.5 sec after the accident (in rpm). Sketch speed (in rpm), torque, and power from to to to+ 2sec.
