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 .
