In the context of thin rings, what happens to the hoop stress as the radius of the ring increases?

57. In the context of thin rings, what happens to the hoop stress as the radius of the ring increases?

1. Hoop stress increases linearly with radius
2. Hoop stress decreases linearly with radius
3. Hoop stress is inversely proportional to the radius
4. Hoop stress remains constant regardless of the radius

Answer

The correct answer is: B) Hoop stress decreases linearly with radius

Explanation

The hoop tension falls linearly with increasing thin ring radius. This is so that there is less stress per unit area as a bigger radius distributes the external strain across a wider region.
