simplified flanged pipe joint for liquid oxygen is pictured below. The internal pressure is 1000psi with an axial tensile load of 800 lbf. If the factor of safety should be at least four, determine the appropriate dimensions for BC, D, L, and the number of bolts and their preload given that ID = 4.026in., WT = 0.237in (4in. Sch.40), and fillet radius of 0.25in. The joint is made of 304L stainless steel and the bolts are to be Grade 8. Ignore any gaskets.
