Explain the following terms:
(a) tensile stress;
(b)Young’s modulus
Verified Correct Answer: .
Physical Principles & Numerical Solution
(a) Tensile stress is the ratio of force to cross-sectional area of a wire/rod. It is expressed in Newton per metre squared (Nm\(^{-2}\))
(b) Young’s modulus is the ratio of tensile stress to tensile strain. It is expressed in Newton per metre squared. (Nm\(^{-2}\))
