The W250 x 45 beam shown above has an allowable bending stress of ?????? = 150 MPa and an allowable shear stress of ?????? = 80 MPa. a) Draw the BMD and SFD of the beam and indicate ???? and ????. b) Determine if the W250 x 45 beam is sufficient to support the loads under bending. c) Determine if the W250 x 45 beam is sufficient to support the loads under shear. d) Overall, state if the W250 x 45 beam is appropriate for this particular application. If not, suggest an alternative section that you feel would be more suitable (and justify your choice).
