Question

A thin hollow cylinder of diameter ${}^{\prime }{d}^{\prime }$, length $L$ and thickness ${}^{\prime }{t}^{\prime }$ is subjected to an internal pressure ${}^{\prime }{p}^{\prime }$. The hoop stress in the cylinder is

• A. $\frac{pd}{8t}$
• B. $\frac{pd}{4t}$
• C. $\frac{pd}{2t}$
• D. $\frac{pd}{8t}$

Answer 1

The correct option is C $\frac{pd}{2t}$

$Hoopstress,{\sigma }_h=\frac{pd}{2t}$
Hoop stress is twice the Longitudinal stress.
