Question

An electric motor turns a llywheel through a drive belt that joins a pulley on the motor and a pulley that is rigidly attached to the flywheel as shown in the figure below. The flywheel is a solid disk with a mass of 53.0 kg and a radius R -0.625 m. It turns on a frictionless axle. Its pulley has much smaller mass and a radius of 0.230 m. The tersion in the upper (taut) segment of the belt is 151 N, and the flywheel has a clockwise angular acceleration of 1.67 rad/s2. Find the tension in the lower (slack) segment of the belt.

Answer 1

for torque on fly wheel (Tu-TL)n = IX (TU-TUM = mex (151-T)*0-230 = 53 x6:625) x1-67 0.230 2 T2 = 75.8 N
