A uniform metallic circurlar disc of mass M and radius R, mounted on frictionless bearings, is rotating at an angular speed omega about an axis passing through its centre and perpendicular to its plane. The temperature of the disc is then increased by Deltat . If alpha is the coefficient of linear expansion of the metal.

A copper rod of length l_(0) at 0^(@) C is placed on smooth surface. Now, the rod is heated upto 100^(@) C. Find the longitudinal strain developed. ( alpha =coefficient of linear expansion)

A uniform rod of length L pivoted at one end P is freely rotated in a horizontal plane with an angular velocity omega about a vertical axis passing through P. If the temperature of the system is increased by Delta T , angular velocity becomes omega/2 . If coefficient of linear expansion of the rod is alpha (altlt1) , then DeltaT will be
