23. What does the polar moment of inertia mean when it comes to circular shafts?
- It measures the resistance of the shaft to shear
- It measures the resistance of the shaft to torsion
- It measures the resistance of the shaft to bending
- It measures the resistance of the shaft to axial loading
Answer
The correct answer is: B) It measures the resistance of the shaft to torsion
Explanation
The resistance of a shaft to torsion is vital to figuring out its torsional behavior.
