A wheel on a shaft is initially at rest, when a motor starts to supply constant torque. The wheel has rotational inertia I=19.4 kg m2 about the shaft. If the motor needs to supply torque so that the wheel will make exactly 3 full revolutions in time t=3.0 seconds (starting from rest), how much torque must the motor supply?

(b) An electric unicycle is composed of a single wheel and an electric motor. The manufacturer specifications state that it must accelerate from 0 to 10 mph in 3.8 seconds, for a given torque T. The wheel would rotate with 1000 rpm if it is travelling at 10 mph. According to the motor’s manufacturer, the same electric motor with the same torque T would accelerate from rest to 1000 rpm in 0.95 seconds, assuming the damping and losses to be...

The combination of an applied force and a frictional force produces a constant torque of 40 N·m on a wheel rotating about a fixed axis. The applied force acts for 8.0 seconds, during which time the angular speed of the wheel increases from 0 to 700 degrees/second. The applied force is then removed, and the wheel comes to rest in 55 s. Answer the following questions. (a)What is the magnitude of the angular acceleration of the wheel while the applied...

A torque of 35.0 N · m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 10.5 rad/s. After 6.10 s the directed force is removed, and the wheel comes to rest 60.2 s later. (a)What is the wheel's moment of inertia (in kg ·...

A wheel with radius 0.0600 m rotates about a horizontal frictionless axle at its center. The moment of inertia of the wheel about the axle is 2.50 kg⋅m2. The wheel is initially at rest. Then at t=0 a force F(t)=(5.50N/s)t is applied tangentially to the wheel and the wheel starts to rotate. What is the magnitude of the force at the instant when the wheel has turned through 8.00 revolutions?
