GATE Mechanical 2014 Set 1 | Question: 6
A circular rod of length $'L'$ and area of cross-section $ A'$ has a modulus of elasticity $ E'$ and coefficient of thermal expansion $ \alpha'$. One end of the rod is fixed and other end is free. If the temperature of the rod ... is $ \alpha \Delta T$ stress developed in the rod is $E \alpha \Delta T$ and strain developed in the rod is zero
