Q3: A steel pressure vessel shown in figure (2) below is sealed by a steel gasketed cap fastened with 8 preloaded bolts as shown in figure below. The cylinder stores gas at a maximum pressure Pg=1220 psi. The thickness of the gasketed cap is te =0.55 in, the diameter of the cylinder is de = 3.3 in, and the diameter of the bolt circle is dbc=5.8 in. Also, tp=0.55 in. It has been decided to use 7/16 -14 UNC 5/4 SAE Grade 8 hex-head bolts with washer. You may assume a non-permanent connection. Determine (a) the load factor nL, and (b) the joint separation factor no. (Elasticity modulus for steel, Estee=31 Mpsi). dhe - de Figure (2) 000
