An electric motor turns a flywheel through a drive belt that joins a pulley on the motor and a pulley that is rigidly attached to the flywheel as shown in Figure P10.29. The flywheel is a solid disk with a mass of m = kg and a radius r = m. It turns on a frictionless axle. Its pulley has much smaller mass and a radius of r1 = m. The tension Tu in the upper (taut) segment of the belt is t = N, and the flywheel has a clockwise angular acceleration of a = rad/s2. Find the tension in the lower (slack) segment of the belt.
