Explanation:

Ques 2 Define Young’s Modulus of elasticity. How much force is required to have an increase of 0.4% in the length of a metallic wire having radius of 0.2mm.

Y = 9.1 x 1010 Nm–2

Ans: Young's modulus is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression. Sometimes referred to as the modulus of elasticity, Young's modulus is equal to the longitudinal stress divided by the strain.
