7. (Combined loading) The beam shown is loaded in the xy and xz planes. (a) Find the y- and z-components of the reactions at the supports. (b) Plot the shear-force and bending-moment diagrams for the xy and xz planes. Label the diagrams properly and provide the values at key points. (c) Determine the net shear-force and bending-moment at the key points of part (b) (d) Determine the maximum tensile bending stress by using the cross section given in Problem 4 (a). 3 in 200 lbf 500 lbf in B X 7.
