Question

A wire increases by 10^(-3) of its length when a stress of 1xx10^(8)Nm^(-2) is applied to it. What is the Young's modulus of the material of the wire?

Answer 1

Answer:

$y \: = \frac{force \times l}{area \times elongation} \\ y = \frac{ {10}^{8} }{ {10}^{ - 3} } = {10}^{11}$

stress = Force per unit area.
