Dynamics of rotational motion about fixed axis
Question

In first figure a meter stick, half of which is wood and the other half steel is pivoted at the wooden end at A and a force is applied at the steel end at O. In second figure the stick is pivoted at the steel end at O and the same force is applied at the wooden end at A.The angular acceleration

Moderate
Solution

Torque will be same in both cases, but moment of inertia is less in second case, hence angular acceleration is greater in this case.
