Problem 1 [18 points]: A piping system transports a fluid that has an internal pressure of 1,500 kPa. In addition to the fluid pressure, the piping supports a vertical load of 9 kN and a horizontal load of 13 kN at the flange A. The pipe has an outside diameter of D=200mm and an inside diameter of d=176mm. At point H, determine a) the principal stresses b) the maximum (in-plane) shear stress 0.65 m 1.2 m H B H 9 kN 13 kN d=176 mm D-200 mm Cross section. K x
