Two steel rods &an alluminium rod of equal length are joined rigidly such that alluminium rod is above steel&another steel rod is above alluminium rod.All the rods are in a state of zero tension at 0 o C.Find the length of the system when the temperature is raised to .coeffs. of linear expansions of alluminium&steel are a and s respectively.youngs modulus are Y a and Y s.
