A rectangular box-section beam is welded to a 180-rnm diameter shaft (Figure P5.53). The box-section has external dimensions 100 mm by 180 mm and a wall thickness of 20 mm. Both members are made of an aluminum alloy (E = 72 GPa and G = 27 GPa). For a load Q = 16 kN, determine the vertical deflections at the free ends of the beam and shaft.
