Sample Questions

Question 1
A cylindrical steel bar with an initial cross-sectional area of A0 = 100 mm² is subjected to an axial tensile force of F = 50 kN. What is the engineering stress (σ) experienced by the bar?
500 kPa
500 MPa
50 MPa
5 GPa
Question 2
A tensile specimen with a gauge length of L0 = 200 mm elongates to a length of L = 200.4 mm under an applied load. What is the engineering strain (ε)?
0.02 (2.0%)
0.004 (0.4%)
0.002 (0.2%)
0.0002 (0.02%)
Question 3
A structural steel rod of diameter d = 10 mm and original length L0 = 0.5 m is subjected to a tensile force F = 16.5 kN within its elastic limit. Given Young's modulus E = 210 GPa for steel, calculate the total elongation (ΔL) of the rod.
1.00 mm
2.00 mm
0.50 mm
0.25 mm
Question 4
In a Brinell hardness test on a metallic alloy, a hardened steel ball of diameter D = 10 mm is applied under a load F = 3000 kgf. The measured indentation diameter is d = 4.0 mm. Calculate the Brinell Hardness Number (HB). [Formula: HB = 2F / (π D (D - √(D² - d²)))]
150 HB
229 HB
310 HB
450 HB
Question 5
In a Charpy impact test, a heavy pendulum striker of mass m = 20 kg is released from a height h1 = 1.5 m. After fracturing the notched test specimen, the pendulum swings to a maximum height h2 = 0.6 m on the opposite side. Assuming g = 9.8 m/s², what is the impact energy absorbed by the specimen?
117.6 J
176.4 J
411.6 J
294.0 J
