I think the ratio of d/t is deciding factor.

(tangential stress) max = pressure + TANGENTIAL STRESS minimum.

Yes off course tangential stress (or) sheer stress is load/2 area so.

Tangential stress will be pD/2t and given question relate with pressure, D/t is more value, therefore, tangential stress more than the pressure.

Why does longitudinal stress is doubled?

Roshan Rai said:   8 years ago
What I think is that in thick cylinder the internal pressure is balanced by both radial stress and hoop stress (tangential stress). So its obvious that the max hoop stress is always less then the internal pressure of the cylinder.

Since tangential stress is double the longitudinal stress.

I think D/t factor is responsible for it greater than internal pressure.

MAX TANGENTIAL STRESS = Pd/8t.

Tangential stress is double of longitudinal stress.
