Question

The ratio of tensile stress developed in the wall of a boiler in the longitudinal direction to the tensile stress in the circumferential direction due to an internal pressure is

• A. $4$
• B. $2$
• C. $1/4$
• D. $1/2$

Answer 1

The correct option is D $1/2$

$\frac{\text{Longitudinal stress}}{\text{Hoop stress}}=\frac{pd/4t}{pd/2t}=\frac{1}{2}$
