For the cylinder of Problem  compute the tangential stress that would have been predicted if thin-walled theory were used instead of thick-walled theory. Compare the result with the stress found in Problem. Compute the maximum longitudinal, hoop, and radial stresses in the wall of a standard j-in schedule 40 steel pipe when carrying an internal pressure of 1.72 MPa (250 psi). The barrel of a large field-artillery piece has a bore of 220 mm and an outside diameter of 300 mm. Compute the magnitude of the hoop stress in the barrel at points 10 mm apart from the inside to the outside surfaces. The internal pressure is 50 MPa. A lj-in schedule 40 steel pipe has a mean radius less than 10 times the wall thickness and thus should be classified as a thick-walled cylinder. Compute what maximum stresses would result from both the thin-wall and the thick-wall formulas due to an internal pressure of 10.0 MPa.  A cylinder has an outside diameter of 50 mm and an inside diameter of 30 mm. Compute the maximum tangential stress in the wall of the cylinder due to an internal pressure of 7.0 MPa. For the cylinder of Problem  compute the radial stress in the wall at increments of 2.0 mm from the inside to the outside. Then plot the results for stress versus radius.
