An automobile engine can produce 200Nm of torque. Calculate the angular acceleration produced if 95.0 of this torque is applied to the drive shaft, axle, and rear wheels of a car, given the following information. The car is suspended so that the wheels can turn freely. Each wheel acts like a 15.0-kg disk that has a 0.180-m radius. The walls of each tire act like a 2.00-kg annular ring that has inside radius of 0.180 m and outside radius of 0.320 m. The tread of each tire acts like a 10.0-kg hoop of radius 0.330 m. The 14.0-kg axle acts like a rod that has a 2.00-cm radius. The 30.0-kg drive shaft acts like a rod that has a 3.20-cm radius.
A rod 7.0 m long is pivoted at a point 2.0 m from the left end. A downward force of 50 N acts at the left end, and a downward force of 200 N acts at the right end.

In the figure, what magnitude of force F→ applied horizontally at the axle of the wheel is necessary to raise the wheel over an obstacle of height h = 0.284 m? The wheel's radius is r = 0.685 m and its mass is m = 1.50 kg.
The figure shows a bicycle wheel resting against a small step whose height is h = 0.130 m. The weight and radius of the wheel are W = 16.0 N and r = 0.340 m. A horizontal force is applied to the axle of the wheel. As the magnitude of increases, there comes a time when the wheel just begins to rise up and loses contact with the ground. What is the magnitude of the force when this happens?
During a testing process, a worker in a factory mounts a bicycle wheel on a stationary stand and applies a tangential resistive force of 120 N to the tire's rim.

A bicycle wheel is 64.6 cm in diameter and weighs 1.87 kg. Assume the wheel is a hoop, with all of the mass focused on the radius on the outside.
