Question

Which of the following is the formula for circumferential stress in a thin-walled cylinder? (Where d = diameter of shell and t = thickness of shell)

• A. pd/3t
• B. pd/8t
• C. pd/6t
• D. pd/2t

Answer 1

Answer:

D. pd/2t

The formula for circumferential stress in a thin-walled cylinder is given by $\sigma_{h} = \frac{PD}{2t}$ where P is pressure, d is diameter, and t is thickness of the shell. The ratio of circumferential stress to longitudinal stress is 2.
