Topic: Strength of Materials
A solid shaft can resist a bending moment of 6 kN m and a torque of 8 kN m applied together. The maximum torque that the shaft can resist when applied alone is
- A. 7 kN m
- B. 48 kN m
- C. 10 kN m
- D. 14 kN m
Answer: C. 10 kN m
Explanation: Equivalent torque T_eq = $\sqrt{M² + T²}$ = $\sqrt{6^2 + 8^2}$ = $\sqrt{36 + 64}$ = 10 kN m.
