Abeam of rectangular cross-section is subjected to a bending moment m (n. m) and a maximum shear force v (n), the bending stress in the beam is calculated as ? -6mbh2 (pa), and average shear stress is calculated as ? ? v/2bh (pa), where b is the width and h is the depth of the beam. the allowable stresses in bending and shear are mpa and -3 mpa, respectively. it is also desirable that the depth of the beam not exceed twice its width and that the cross-sectional area of the beam be minimized. m-80 kn and v=150 kn.
