Elastic behaviour of solids

Question

The strain-stress curves of three wires of different materials but of identical shape and size are shown in the figure. P, Q and R are the elastic limits of the wires, The figure shows that

Moderate

A

elasticity of wire P is maximum
B

elasticity of wire Q is maximum
C

tensile strength of R is maximum
D

None of the above

Solution

As stress is shown on X-axis and strain on Y-axis. So,
we can say that $y = \cot θ = \frac{1}{\tan θ} = \frac{1}{slope}$
So, elasticity of wire P is minimum and of wire R is maximum
