The tapered, two-cell beam is subjected to a pure torque of 50,000 in-lb counter clockwise. The length of the beam (normal to the figure) is 100 in. The flange areas are 1 sq in and all wall thicknesses are 0.01 in. G = 4 mpsi. Calculate the shear flows at the wall (far end) and the total twist of the free end (near end).
