Consider the following statements:
1. In case of a thin spherical shell of diameter d and thickness t, subjected to internal pressure p, the principal stresses at any point equal pd/4t
2. In case of thin cylinders the hoop stress is determined assuming it to be uniform across the thickness of the cylinder
3. In thick cylinders, the hoop stress is not uniform across the thickness, but it varies from a maximum value at the inner circumference to a minimum value at the outer circumference.
