Why it will not hoop stress, why only longitudinal stress?

Rakesh said:   5 years ago
Here, it should be mention hoop or longitudinal stress. Then only one can say whether it is 2t or 4t.

The axial stress of cylinder = Spherical stress.

Thank you for the explanation.

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

Thanks for all the explanation.

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

Ashok said:   8 years ago
As it is a spherical shell, so pd/4t is correct.

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

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.
