Question 1
Which formula correctly defines tensile stress (sigma) acting uniformly across a solid structural member with cross-sectional area A subjected to axial tension force F?
Correct Answer:
sigma = F / A
Question 2
Engineers measure tensile strain (epsilon) during a destructive tensile test. What is the standard definition and unit of tensile strain?
Correct Answer:
Change in length divided by original length; dimensionless quantity
Question 3
Within the linear elastic region of a material's stress-strain curve, Hooke's Law states that Young's modulus (E) is equal to:
Correct Answer:
Stress divided by strain (sigma / epsilon)
Question 4
Which mechanical property describes a material's capability to undergo significant permanent plastic deformation under tensile load before fracturing?
Correct Answer:
Ductility
Question 5
Which hardness testing method presses a hardened steel or tungsten carbide ball into a specimen under a specified load and measures the indentation diameter?
Correct Answer:
Brinell hardness test
