A composite rod is made by joining a copper rod, end to end, with a second rod of different material but of the same area of cross section. At 25C, the composite rod is 1m long and the copper rod is 30cm long. At 125C the length of the composte rod increases by 1.91mm. When the composite rod is prevented from expanding by bolding it between two rigid walls, it is found that the constituent reds have remained unchanged in length in split of rise of temperature. Find young’s modulus
