According to bending formula;
M/I = F/Y = E/R.
F is directly proportional to y.
or f is directly proportional to r.

@Baloch.

P means internal pressure.

And t means the thickness of cylinder.

Baloch said: 5 years ago

Then, What is the value of p and t?

For cylinder hoop stress = pd/2t.
Longitudinal stress = pd/4t.

For sphere hoop stress = longitudinal stress = pd/4t.

Stress m = F * D or m = W * L so f is force and d is distance and w is load and L is distance for taking a moment so it's proportional to distance.

Pd/4t for longitudinal stress.

Where r =d/2 Substitute the r in the above formula sigma is d.proportional to r.
