(2) In a fatigue loading situation (Se=30, Sut=100, Sy=80, all in ksi), the slope of the load line is 0.5. What are the limiting values of mean and alternating stresses according to the Goodman Criterion? 2) The Hoop and axial stresses in a thin walled steel pressure vessel (2" diameter, 15" long, and 0.1" thick.) are 20 ksi and 10 ksi, respectively. What is the change in the diameter of the vessel? E= 30 msi, v0.3, G=11.5 mst 2) In a tension spring, the preload is one Ib and the spring rate is 2 lb/in. If the spring is stretched 2", how much energy is stored in it?
