A large reel of paper installed at the end of a paper machine. d1 = 2m, J = 1000kgm^2, n1 = 60rpm, Tension on Paper = 1000N. Calculate:
a. Motor power when the reel turns at 60rpm.
b. Torque to increase speed to 120 rpm in 10 seconds.
c. Motor power at 11 sec. d. Sketch speed, torque, and power. Include all necessary numbers.
