Question

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

(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 is true

Answer 1

Correct option  (d) None of the above is true

Explanation:

On the graph stress is represented on X- axis and strain Y-axis So from the graph

We can say that elasticity of wire P is minimum and R is maximum
