The system shown in figure consists of three springs and two rods as shown. These springs are initially relaxed and there is no friction. The temperature of each of the rod is increased by DeltaT. The coefficient of linear expansion of the material of rods is equal to alpha.

1.	The system shown in figure consists of three springs and two rods as shown. These springs are initially relaxed and there is no friction. The temperature of each of the rod is increased by DeltaT. The coefficient of linear expansion of the material of rods is equal to alpha.
Answer» The energy STORED in spring `S_` is `(81)/( 242) KL^(2) alpha (Delta T)^(2) ` The energy stored in spring `S_2` is `(81)/( 484) kL^(2) alpha^(2) ( Delta T)^(2)` The energy stored in spring `S_(3)` is `(27)/( 242) kL^(2) alpha^(2) ( Delta T)^(2)` No energy is stored in any of the springs.
