QUESTION: 1

What is the thickness of the shell of a bomb calorimeter of spherical form of 10 cm inside diameter if the working stress is σMPa and the internal pressure is σ/2 MPa? [Take 21/3 = 1.26]

Solution:


at r = a, σθ is maximum


Thickness of bomb shell

QUESTION: 2

The radial stress in a thin spherical pressure vessel is

Solution:
QUESTION: 3

Hoop stress in a thin cylinder of diameter dand thickness t subjected to pressure p will be

Solution:

Due to fluid pressure p in the cylinder bursting force = p x d x L
This is resisted by thickness of cylinder Resisting force = σh(2t x L).
For equilibrium
Resisting force = Bursting force

where σh = hoop stress
p = internal fluid pressure
d = Diameter of cylinder
t = Thickness of cylinder

QUESTION: 4

Longitudinal stress in a thin cylinder of diameter d and thickness t subjected to pressure p will be

Solution:

QUESTION: 5

A thin cylindrical shell of internal diameter d and thickness ‘t’ is subjected to internal pressure ‘p’. The change in diameter is given by

Solution:







∴ 

QUESTION: 6

In above case the longitudinal strain is

Solution:



QUESTION: 7

A thin cylindrical shell of diameter d, length L and thickness t is subjected to an internal pressure p. What is the ratio of longitudinal strain to hoop strain in terms of Poisson’s ratio (1/m)?

Solution:


Hoop strain,

∴ 

QUESTION: 8

The volumetric strain in case of a thin cylindrical shell of diameter d, thickness t, subjected to internal pressure p is

Solution:


QUESTION: 9

The design of thin cylindrical shells is based on

Solution:

Since hoop stress (σh) > Longitudinal stress (σL). Hence to have safe design, hoop stress is considered.

QUESTION: 10

The commonly used technique of strengthening thin pressure vessels is

Solution:
