What happens to the wall thickness of a thin cylindrical shell under internal pressure?

62. What happens to the wall thickness of a thin cylindrical shell under internal pressure?

1. It increases
2. It decreases
3. It fluctuates unpredictably
4. It remains constant

Answer

The correct answer is: B) It decreases

Explanation

Under internal pressure, thin cylindrical shells tend to expand, resulting in a reduction in wall thickness. This reduction occurs due to the stretching of the material.
