Question

A solid circular shaft of diameter 'd' is subjected to a combined bending moment 'M' and torque "T. The material property to be used for designing the shaft using the relation $\frac{16}{\pi d^3} \times \sqrt{M^2+T^2}$ is:

• A. Ultimate tensile strength (σx)
• B. Torsional yield strength (σsy)
• C. Endurance strength (σe)
• D. Tensile yield strength (σy)

Answer 1

Answer: (B)

Torsional yield strength (σsy)

Answer 2

The correct option is (B): Torsional yield strength (σsy)
