In thin cylinder, circumferential stress is x times longitudinal stress, where x is
Hoop stress, σh =
longitudinal stress σl =
If the cylindrical pipe is subjected to internal fluid pressure, the nature of hoop stress is
A thin cylinder with closed ends is subjected to internal pressure and supported at ends as shown in figure. What is the state of stress at point x?
No. shear stress, τ Hoop and axial stresses act, both are tensile.
Maximum value of shear stress in thin cylinders is equal to
A thin cylinder with both ends closed is subjected to internal pressure p. The longitudinal stress at the surface has been calculated as σ0 . Maximum shear stress at the surface will be
τmax = = σ0
If the hoop strain and longitudinal strain in case of a thin cylindrical shell are eh and et then volumetric strain is
A pipe having internal diameter d, wall thickness t and internal pressure p, the bursting pressure is
A thin cylinder contains fluid at a pressure of 500 MN/m2, internal diameter of the shell is 0.6 m and tensile stress in the materials is to be limited to 9000 N/m2. The shell must have a minimum thickness of nearly
t = 16.66 ≃ 17 mm
When is the safe working pressure for a spherical pressure vessel 1.5 m internal diameter and 1.5 cm wall thickness if the maximum allowable tensile stress in vessel is 45 MPa?
P = = 1.8 MPa
What is the safe working pressure for a spherical pressure vessel 1.5m internal diameter and 1.5cm wall thickness, if the maximum allowable tensile stress is 45 MPa?
P ≤ 1.8 MPa For safe working, pressure should be less than 1.8 MPa
