QUESTION: 1

A thin cylindrical steel pressure vessel of diameter 6 cm and wall thickness 3 mm is subjected to an internal fluid pressure of intensity ’ p'. If the ultimate strength of steel is 3600 kg/cm2, the bursting pressure will be

Solution:

Hoop stress is more than longitudinal stress.

QUESTION: 2

QUESTION: 6

A thick-walled hollow cylinder having outside and inside radii of 90 mm and 40 mm respectively is subjected to an external pressure of 800 MN/m2. The maximum circumferential stress in the cylinder will occur at a radius of

Solution:

The maximum circumferential stress in a thick cylinder occurs at the inner radius, i.e. 40 mm.
