The figure shows a steel pressure cylinder of diameter 4 in which uses six SAE grade 5 steel bolts having a grip of 12 in. These bolts have a proof strength (see Chap. 8) of 85 kpsi for this size of bolt. Suppose the bolts are tightened to 90 percent of this strength in accordance with some recommendations.
(a) Find the tensile stress in the bolts and the compressive stress in the cylinder walls.
(b) Repeat part (a), but assume now that a fluid under a pressure of 600 psi is introduced into the cylinder.
