Question. Two steel rods & an aluminium rod of equal length land equal cross-section are joined rigidly at their ends as shown in the figure._______________________________________|______________________________________|<-------steel|______________________________________|<-------aluminium|______________________________________|<-------steelAll the rods are in the state of zero tension at 0°C. Find the lenght of the system when the temperature is raised to θ°C. Coefficient of linear expansion of aluminium & steel are α1 and α2, respectively. Young's modulus of aluminium is Y1 and of steel is Y2..
