alleryStart learning →Stress is defined as:
AVolume × pressure
BForce per unit area (F/A); SI unit pascal (Pa = N/m²)
CForce × Area
DForce/length
Answer & Solution
Correct answer: B. Force per unit area (F/A); SI unit pascal (Pa = N/m²)
Stress σ = F/A. Tensile, compressive, shear are basic types. Pa = N/m².
**Typical magnitudes:** steel yield ~250-500 MPa
concrete compressive ~20-40 MPa.
