Figure below shows the strain-stress curve for a given material. What are

(a) Young’s modulus and

(b) approximate yield strength for this material?

Asked by Abhisek | 1 year ago |  95

##### Solution :-

Young’s modulus ,Y =$$\dfrac{Stress}{Strain}$$

=$$\dfrac{150 \times 10^6}{0.002}$$

$$\dfrac{150 \times 10^6}{2 \times 10^{-3}}$$

= 75 x 109 Nm-2

=75 x 1010 Nm-2

(a) Yield strength of a material is the maximum stress that the material can sustain and retain its elastic property.

From graph, the approximate yield strength of the given material

= 300 x 106 Nm-2

= 3 x 108 Nm-2 .
