Tensile stress and strain: A 0.600-mm diameter wire stretches 0.500% of its length when it is stretched with a tension of 20.0 N. What is the Young's modulus of this wire?

Question

Quizplus · Accepted Answer

Young's modulus (E) is calculated using the formula E = (F/A) / (ΔL/L), where F is the force, A is the cross-sectional area, ΔL is the change in length, and L is the original length. The cross-sectional area A = π(d/2)^2, where d is the diameter. Substituting the given values and solving gives E = 1.41 × 10^10 N/m^2.
