A metal rod of length L and cross-sectional area A is heated through T^{\circ} {C}. What is the force required to prevent the expansion of rod lengthwise?

Correct Answer is : YAαT(1+αT)

\frac{Y A \alpha T}{(1-\alpha T)}

\frac{Y A \alpha T}{(1+\alpha T)}

\frac{(1-\alpha T)}{Y A \alpha T}

\frac{(1+\alpha T)}{Y A \alpha T}
