Question:medium

A steel rod with a circular cross-section of diameter 1cm and another steel rod with a square cross-section of side 1cm have equal mass. If the two rods are subjected to same tension, the ratio of the elongations of the two rods is

Show Hint

In problems comparing properties of objects with equal mass and material, first use the mass equality ($M = \rho L A$) to find the ratio of their lengths or areas. Then use this ratio in the formula for the property you are comparing (like elongation, resistance, etc.).
