A wheel of radius 10 cm can rotate freely about its centre as shown in fig.A string is wrapped over its rim and is pulled by a force of 5.0N .It is found that the torque prodces an angular acceleration 2.0 rad//s in the wheel.calculate the moment of inertia of the wheel.

A constant torque acting on a uniform circular wheel changes its angular momentum from L to 4 L in 4 seconds.The magnitude of torque is :

To maintain a rotor at a uniform angular speed of 200 rad s^-l , an engine needs to transmit a torque of 180 N m. What is the power required by the engine ? (Note: uniform angular velocity in the absence of friction implies zero torque. In practice, applied torque is needed to counter frictional torque). Assume that the engine is 100% efficient.

m_1 and m_2 are the masses of two bodies. When a force of 5 N is applied on each body, m_1 gets an acceleration of 10 m//s^2 and m_2, 20 m//s^2. If the two bodies are tied together and the same force is applied, find the acceleration of the combined system.
