Question

(d) As stress is shown on $x-$axis and strain on $y-$axis

So we can say that $Y = \cot 	heta = \frac{1}{{	an 	heta }} = \frac{1}{{{m{slope}}}}

Vedclass · Accepted Answer

None of the above is true

(d) As stress is shown on $x-$axis and strain on $y-$axis

So we can say that $Y = \cot 	heta = \frac{1}{{	an 	heta }} = \frac{1}{{{m{slope}}}}$

So elasticity of wire $P$ is minimum and of wire $R$ is maximum
