In case of thin spherical shell hoop and longitudinal stresses are same as here length and dia are not two separate things. Both are equal. That's why when we equal resisting stress to the stress due to internal pressure same value is obtained for hoop and longitudinal.

Should mention clearly either longitudinal stress/circumferential (hoop) stress.

As it is a spherical shell, so pd/4t is correct.

Stress in the shell material means longitudinal stress. Why not hoop stress?

It is a spherical shell. So hoop stress and longitudinal stress = pd/4t.

Thanks for all the explanation.

Here is not mentioned that is it speaking for longitudinal stress or circumference stress in thin spherical.

The axial stress of cylinder = Spherical stress.

Here, it should be mention hoop or longitudinal stress. Then only one can say whether it is 2t or 4t.
