Answer:
Where stress is the amount of force applied per unit area (σ = F/A) and strain is extension per unit length (ε = dl/l). Since the force F = mg, we can obtain the Young's modulus of a wire by measuring the change in length (dl) as weights of mass m are applied (assuming g = 9.81 metres per second squared).
