Question 8 CITY_GUILDS_MODEL_QUESTIONS_VOL1 • 2023 • ENGINEERING • objective

A solid steel rod 2 m long has a circular cross‑section of diameter \(20\ \text{mm}\). It is subjected to an axial load of \(30\ \text{kN}\) and, due to an eccentric load, a bending moment of \(0.05\ \text{kNm}\). The steel has a yield strength of \(250\ \text{MPa}\). Using the von Mises criterion, determine whether the rod will fail. (Give the von Mises stress in MPa and state if it is safe.)

Answer Options

Correct Answer A. Safe (von Mises stress ≈ 146 MPa)
B. Unsafe (von Mises stress ≈ 260 MPa)
C. Safe (von Mises stress ≈ 120 MPa)
D. Unsafe (von Mises stress ≈ 140 MPa)
Correct Answer
A
Correct Option:
Safe (von Mises stress ≈ 146 MPa)
