Can explain, how the area will get?

It is similar to longitudinal stress in the thick cylinder.
σ*π(ro2-ri2)=p*area.

Give me the brief explanation of the solution, please!

Anyone, please explain it briefly.

Yes, stress = pressure/Area.

Area of cylindrical shell = (ri^2 - ro^2)/(ri^2+ro^2).
Hence, stress= p(ri^2+ro^2)/(ri^2-ro^2).

Stress=pressure*Area(pressure)/Area(stress).
Area (Pressure)=π/4(ri^2+r0^2) Area (Stress)=π/4(ri^2-r0^2).

Can anyone explain the formula.

Roshan Gaykar said:   7 years ago
It is a standard formula illustrates in thin cylindrical shell chapter.

Ankit kumar said:   7 years ago
This is a standard formula also derived by R. S Khurmi book.

Can anyone give its derivation, for proper understanding?
