a.) Determine the maximum shear stress in a rectangular beam 6 in. wide and 8 in. deep produced by a shear force of 38,400 lb.
b.) For the same section and shear force conditions of part (a) above. Determine the shear stress 3 inches above the neutral axis in the beam.
(c)Determine the bending moment in a rectangular beam 2 in. wide and 4 in. deep, if the maximum bending stress is 20,000 psi.
(D)Due to a leak in Pump Station 1,the Alaska pipeline is shut down briefly.The pipe line is half full.Assume the pipe is welded horizontally at its midpoint.What is the tensile force on the weld per foot? Assume Ø=40”and ?oil=53.55lb/ft3.
