Elastic Modulie

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

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 is true

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.
