Two steel (E=30,000 ksi) pipes (1) and (2) are connected at flange B. Pipe (1) has an outside diameter of 6.625 in. and a wall thickness of 0.28 in. Pipe (2) has an outside diameter of 4.00 in. and a wall thickness of 0.226 in. If the normal stress in each steel pipe must be limited to 18 ksi determine:
a) The maximum downward load P that may be applied at flange B.
b) The deflection of flange B at the load determined in part (a)
