A composite beam consisting of a steel beam and an aluminium plate is simply supported at both ends and is under a concentrated load of 150 kn which can act on any part of the beam. a) considering all possble locations of the load find extreme values (maximum and minimum) of the bending moment in the beam and shear force in the beam. for the cross section of the beam shown, assuming that both the i beam and the top plate act as a single beam without any relative sliding, determine b) the max tensile, compressive and shear stress in the steel and aluminium c) suggest a suitable arrangement of bolts to connect the plat to the beam.
