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
