A wheel on a shaft is initially at rest, when a motor starts to supply constant torque. The wheel has rotational inertia I=20.4 kg mabout the shaft. If the motor needs to supply torque so that the wheel will make exactly 3 full revolutions in time t=5.5 seconds (starting from rest), how much torque must the motor supply? 8.47 Nm 0.67 Nm 25.42 Nm 16.19 Nm 12.71 Nm
A flying wheel with a moment of inertia of 4kg m2 is initially at rest. If a torque of 10 Nm (clockwise) is suddenly applied to the flywheel, what will be the speed of the flywheel after!5 seconds
A torque of 35.9 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 10.3 rad/s. After 6.20 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...
