Question 1
A cylindrical steel specimen with a diameter of 10.0 mm (cross-sectional area A = 78.54 mm²) is subjected to a uniaxial tensile load of 31,416 N. What is the engineering tensile stress σ induced in the specimen?
Correct Answer:
400 MPa
Question 2
A copper rod with initial length L₀ = 2.0 m and cross-sectional area A = 50.0 mm² is pulled in tension by a 6,000 N force. Given Young's modulus E = 120 GPa for copper, what is the elastic elongation ΔL of the rod?
Correct Answer:
2.0 mm
Question 3
In a standard tensile test curve of engineering stress versus engineering strain, what property corresponds to the maximum stress point prior to localized necking?
Correct Answer:
Ultimate tensile strength (UTS)
Question 4
A Brinell hardness test is conducted using a 10 mm diameter hardened steel ball indenter under a load of 3,000 kgf. If the resulting indentation diameter d is measured as 4.0 mm, what is the approximate Brinell Hardness Number (HB)?
Correct Answer:
229 HB
Question 5
Which hardness test uses a square-based diamond pyramid indenter with an apex angle of 136° between opposite faces, applicable across soft and hard metals?
Correct Answer:
Vickers hardness test (HV)
