25. In a hollow circular shaft, how does increasing the thickness of the outer ring affect the Polar Moment of Inertia?
- Remains unchanged
- Depends on the material of the shaft
- Increases
- Decreases
Answer
The correct answer is: C) Increases
Explanation
An increase in the outer ring thickness of a hollow circular shaft induces an increased Polar Moment of Inertia, which in effect increases the shaft's torsional resistance.
