Answer: Shearing stress.
- A Longitudinal stress
- B Shearing stress
- C Volumetric stress
- D Tensile stress
Correct answer: B. Shearing stress
Explanation: Shearing stress is tangential to the surface and deforms shape while keeping volume constant.
A typical stress-strain curve: the initial straight line (Hooke's Law region, slope = Young's modulus) ends at the elastic limit; beyond the yield point, deformation becomes permanent, peaking at the ultimate tensile strength before the wire finally fractures.
Concept context
Stress, strain, Hookes law, and the elastic moduli that describe how solids deform and recover under load.
