The gas tank is made from A-36 steel and has an inner diameter of 1.50 m. If the tank is designed to withstand a pressure of 5 MPa, determine the required minimum wall thickness to the nearest millimeter using (a) the maximum shear stress theory, and (b) maximum distortion energy theory. Apply a factor of safety of 1.5 against yielding.

The gas storage tank is fabricated by bolting together two half cylindrical thin shells and two hemispherical shells as shown. If the tank wall has a thickness of 50 mm for cylindrical and hemispherical shells, The bolts were installed as 40 bolts/meter. The tank and the 25 mm diameter bolts are made from material having an allowable normal stress of 150 MPa and 250 MPa, respectively. The tank has an inner diameter of 4 m. What is the maximum pressure that tank can contain.

A spherical gas tank has an inner radius of r = 1.5 m. If it is subjected to an internal pressure of p = 420 kPa, determine its minimum required thickness if the maximum normal stress is not to exceed 12 MPa.
