Question
A simple pendulum is a point mass suspended by a light thread from a fixed point. The particle is displaced towards one side and then released. It makes small oscillations. Is the motion of such a simple pendulum a pure rotation? If yes, where is the axis of rotation?
✓

Answer

Yes, it is an example of pure rotation.
The axis of rotation passes through the pivot of the pendulum, perpendicular to the plane containing the pendulum.

A metal block of density $6000 \mathrm{~kg} \mathrm{~m}^{-3}$ and mass 1.2 kg is suspended through a spring of spring constant $200 \mathrm{~N} \mathrm{~m}^{-1}$. The spring-block system is dipped in water kept in a vessel. The water has a mass of 260 g and the block is at a height 40 cm above the bottom of the vessel. If the support to the spring is broken, what will be the rise in the temperature of the water. Specific heat capacity of the block is $250 \mathrm{Jkg}^{-1} \mathrm{~K}^{-1}$ and that of water is $4200 \mathrm{Jkg}^{-1} \mathrm{~K}^{-1}$. Heat capacities of the vessel and the spring are negligible.
