Question

2. In order to produce a longitudinal strain of 2 x 10 ,
a stress of 2.4 x 10' N/m' is produced in a wire.
Calculate the Young's modulus of the material of the
wire.
Ans. 1.2 x 10 N/m​

Answer 1

Answer:

1.2 x 10 $\frac{N}{m^{-2} }$

Explanation:

by hooke's law

stress  = young's modulus * longitudinal strain

young's modulus = stress / strain

young's modulus  = 2.4 x 10^2 / 2 * 10 = 1.2 x 10 $\frac{N}{m^{-2} }$
