The safe twisting moment for a compound shaft is equal to the
- a)maximum calculated value
- b)minimum calculated value
- c)mean value
- d)all of these depending on loading condition
Correct answer is option 'B'. Can you explain this answer?

Understanding Safe Twisting Moment for Compound Shafts
In mechanical engineering, the safe twisting moment for a compound shaft is crucial for ensuring safety and functionality. This concept revolves around the ability of a shaft to withstand various torsional loads without failure.
Key Concepts: Safe Twisting Moment
- Definition: The safe twisting moment refers to the maximum torque a shaft can endure without yielding or failing.
- Compound Shaft: A compound shaft is made of different materials or has varying cross-sections, leading to different mechanical properties along its length.
Maximum vs. Minimum Calculated Values
- Maximum Calculated Value: This represents the highest theoretical moment a shaft can sustain based on the material's yield strength. However, it does not consider all loading conditions or factors affecting safety.
- Minimum Calculated Value: This value accounts for the weakest section of the shaft, ensuring that the design is safe under all operational conditions. It is essential for reliability and durability in real-world applications.
Why Choose Minimum Calculated Value?
- Safety Factor: Using the minimum calculated value incorporates a safety factor, which is vital in engineering design. It accounts for uncertainties in material properties, loading conditions, and potential wear over time.
- Real-World Application: In practical scenarios, the loads on shafts can vary significantly. The minimum calculated value ensures that even under worst-case scenarios, the shaft remains safe.
Conclusion
In summary, the safe twisting moment for a compound shaft is determined by the minimum calculated value. This approach ensures that the shaft can withstand varying loads effectively, making it a safer and more reliable choice in engineering designs. Always prioritize safety by considering the weakest points in your calculations.
