The maximum shear stress in a thin cylindrical shell subjected to internal pressure 'p' is
A. $$\frac{{{\text{pd}}}}{{\text{t}}}$$
B. $$\frac{{{\text{pd}}}}{{2{\text{t}}}}$$
C. $$\frac{{{\text{pd}}}}{{4{\text{t}}}}$$
D. $$\frac{{{\text{pd}}}}{{8{\text{t}}}}$$
Answer: Option D
Correct answer should be pd/4t until and unless it not mentioned the case of IN Plane stress problem. i. e. if it is 2D problem then answer is pd/8t. So basically there are three stress hoop, longitudinal and radial. where radial is considered as zero. That is why maximum shear stress equal to Hoop/2
