Question

define young modulus of normal stress and give its unit​

Answer 1

Answer:

heya mate here is your answer....

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.

hope it helps you

Answer 2

Answer:

The young's modulus is defined as the ratio of longitudinal stress to longitudinal strain produced in a wire on application of deformable force upto it's elastic limit. Its unit is the same as that of stress, I.e, N/m^2, as the strain is a unit less quantity.
