NettetYoung’s modulus is also known as the modulus of elasticity. Young’s modulus of elasticity measures the stiffness of an elastic body. The higher the value of Young’s modulus, the stiffer the body becomes. In other words, the higher Young’s modulus, the less elastic the body or the object gets. The unit of Young’s modulus is N/m². NettetSolution: Since Young's modulus is required, we need to find the stress and the strain first (remember, Young's modulus is the ratio of stress over strain). We apply the stress formula to find stress. σ = F A = 60 N 0.02 ⋅ 10 − 6 m 2 = 3 ⋅ 10 9 P a. Then we apply the strain formula to find the strain: ε = L n − L 0 L 0 = Δ L L 0 = 0. ...
