JEE MainPhysicsProperties of MatterMCQ+4 / −1
Four identical hollow cylindrical columns of mild steel support a big structure of mass 50 ×\times× 103 kg. The inner and outer radii of each column are 50 cm and 100 cm respectively. Assuming uniform local distribution, calculate the compression strain of each column. [Use Y = 2.0 ×\times× 1011 Pa, g = 9.8 m/s2]
