A cylinder of length `l` and radius `r` is heated to temperature `T`. A longitudeinal compressive force `F` is applied on cylinder to keep its length same. Find coefficient of volume expansion.

A uniform cylindrical rod of length L and radius r, is made from a material whose Young’s modulus of elasticity equals Y. When this rod is heated by temperature T and simultaneously subjected to a net longitudinal compressional force F, its length remains unchanged. The coefficient of volume expansion, of the material of the rod, is (nearly) equal to:

The radius of a cylinder is r and heigth is h. Find its volume.

The radius of a cylinder is r and heigth is h. Find its volume.

The volume of a cylinder of radius r and length h is

A solid cylinder of length L and radius r is heat upto same temperature as that of a cube of edge length a. If both have same material, volume and allowed to cool under similar conditions, then ratio of amount of radiations radiated will be (Neglect radiation emitted from flat surfaces of the cylinder)
