Engineers are considering two possible vessel shapes for storing fuel. One shape is cylindrical and the other is spherical. Each vessel would be constructed out of the same material such that its hoop stresses and longitudinal stresses would be no greater than 17.0 ksi . The cylindrical pressure vessel has an inside diameter of dc = 30.0 in and a thickness of tc = 1.00 in . The spherical pressure vessel has an inside diameter of ds = 29.0 n and a thickness of a = 0.250 in .

Determine the maximum allowable pressure, pc, max, in the cylindrical pressure vessel.?Determine the maximum allowable pressure, ps, max, in the spherical pressure vessel.?

Determine the required thickness of the cylindrical pressure vessel, tr, if it is subjected to the maximum allowable pressure of the spherical pressure vessel.
