Question

Suppose an automobile engine can produce 220 N⋅m of torque, and assume this car is suspended so that the wheels can turn freely. Each wheel acts like a 15 kg disk that has a 0.155 m radius. The tires act like 1.8-kg rings that have inside radii of 0.18 m and outside radii of 0.305 m. The tread of each tire acts like a 12-kg hoop of radius 0.325 m. The 14-kg axle acts like a solid cylinder that has a 1.85-cm radius. The 30.5-kg drive shaft acts like a solid cylinder that has a 3.2-cm radius.

a) Calculate the angular acceleration, in radians per square second, produced by the motor if 95.0% of this torque is applied to the drive shaft, axle, and rear wheels of a car.
