Coefficient of linear expansion of brass and steel rods are α1 and α2. Lengths of brass and steel rods are l1 and l2, respectively. If (l2 – l1) is maintained same at all temperatures, which one of the following relations holds good?
To solve this problem, we need to consider the condition that the difference in lengths is maintained the same at all temperatures.The change in length of a rod due to temperature change is given by:
