GATE PI 2017 | Thin Cylinders Question 1 | Strength of Materials

GATE PI 2017

MCQ (Single Correct Answer)

-0.3

The inside and outside radii of a thick- walled cylindrical pressure vessel are denoted by $$a$$ and $$b,$$ respectively. If the vessel is subjected to an internal pressure $$P,$$ then the magnitude of the radial stress $${\sigma _{rr}}$$ is

zero at $$r=a$$ and maximum at $$r=b$$

maximum at $$r=a$$ and zero at $$r=b$$

constant over the entire thickness

zero at both $$r=a$$ and $$r=b$$
