What is the effect of change in temperature on the Young’s modulus ?
What is the effect of change in temperature on the Young’s modulus ?
With rise in temperature strain increases hence from formula $\mathrm{Y}=\frac{\text { Stress }}{\text { Strain }}$, Young's modulus decreases and when temperature decreases Young's modulus increases.

A wire of cross sectional area $A$, modulus of elasticity $2 \times 10^{11} \mathrm{Nm}^{-2}$ and length $2 \mathrm{~m}$ is stretched between two vertical rigid supports. When a mass of $2 \mathrm{~kg}$ is suspended at the middle it sags lower from its original position making angle $\theta=\frac{1}{100}$ radian on the points of support. The value of $A$ is. . . . . . $\times 10^{-4} \mathrm{~m}^2$ (consider $\mathrm{x}<\mathrm{L}$ ).
