In the figure (i) half of the meter scale is made of wood while the other half, of steel. The wooden part is pivoted at O. A force F is applied at the end of steel part. In figure (ii) the steel part is pivoted at O and the same force is applied at the wooden end

Two masses are attached to a rod end to end . If torque is applied they rotate with angular acceleration alpha . If their distances are doubled and same torque is applied, then they move with angular acceleration.

The adjacent figure shows a non-uniform metre stick AB having the linear mass density variation lambda = lambda_(0) x , where lambda_(0) is a constant and x is the distance from end A, placed on a smooth horizontal surface. In the first experiment, the rod is pivoted at A and force F is applied perpendicular to the rod at the other end B and in the second experiment, the rod is pivoted at B and the force is applied perpendicular to the rod at the end A. If in the first case angular acceleration is alpha_(A) and in the second case it is alpha_(B) then
