The figure shows a steel pressure cylinder of diameter 5 in that uses six SAE grade 4 steel bolts having a grip of 10 in. These bolts have a proof strength of 65 kpsi. Suppose the bolts are tightened to 75 percent of this strength.
(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 500 psi is introduced into thecylinder.
