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]
2.1 × 105 N/mm2
1.3 × 105 N/mm2
0.7 × 105 N/mm2
1.0 × 105 N/mm2
0.1 × 105 N/mm2
The percent error in calculation of Young's modulus is: [(E1 - E2)/E1] × 100
