Question: A metal bar of length L and area of cross-section A is clamped between two rigid supports. For the material of the rod, its Young’s modulus is Y and coefficient of linear expansion is $\alpha $. If the temperature of the rod is increased by $\Delta {{t}^{o}}C,$ the force exerted by the rod on the supports is


1) $Y\,A\,L\,\Delta t$
2) $Y\ A\ \alpha \,\Delta t$
3) $\frac{YL\alpha \Delta t}{A}$
4) $Y\alpha \,A\,L\,\Delta t$
Solution: Explanation: No Explanation
Young’s Modulus Breaking Stress
