Four rods A, B, C and D of the same length and material but of different radii r, r sqrt(2),r sqrt(3) and 2r respectively are held between two rigid walls. The temperature of all rods is increased through the same range. If the rods donot bend, then a) The stress in the rods A, B, C and D are in the ratio 1:2:3:4 b) The forces on them exerted by the wall are in the ratio 1:2:3:4 c) The energy stored in the rods are due to elasticity are in the ratio 1:2:3:4 d) The strains produced in the rods are in the ratio 1:2:3:4
