Stress &infi; Strain or Stress = E * Strain where, E is the modulus of elasticity of the material of the body. Types of Modulus of Elasticity 1. Young’s Modulus of Elasticity It is defined as the ratio of normal stress to the longitudinal strain Within the elastic limit. y = Normal stress / Longitudinal strain y = FΔl / Al = Mg Δl / πr2l
