Explain Young's Modulus or Modulus of elasticity?

Sol. : It is ratio between tensile stress and tensile strain or compressive stress and compressive strain. It can be denoted by E. It is same as modulus of elasticity

E  =  σ/e [ σt/et  or σc/ec]

S.No.

Material

Young's Modulus(E)

1

Mild steel

2.1 × 105  N/mm2

2

Cast Iron

1.3 × 105  N/mm2

3

Aluminium

0.7 × 105  N/mm2

4

Copper

1.0 × 105  N/mm2

5

Timber

0.1 × 105  N/mm2

The percent error in calculation of Young's modulus is: [(E1  - E2)/E1] × 100
