Question 1

Where does the maximum hoop stress in a thick cylinder under external pressure occur?

Question 2

Consider the following statement for a pressure vessel which is subjected to internal pressure:
1). Radial stress at inner radius is always zero.
2). Radial stress at outer radius is always zero.
3). The tangential stress is always higher than other stresses.
4). The tangential stress is always lower than other stresses.
Which of these statement are correct?

Question 3

A water main of 1 m diameter contains water at a pressure head of 100 meters. The permissible tensile stress in the material of the water main is 25 MPa. What is the minimum thickness of the water main? (Take g = 10 m/s²)
