WebbSolution: 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. ...
