The beam shown in Fig. P7.16 has a cross section of depth 60 mm and width 30 mm. The load P and reactions R and R2 all lie in a plane that forms an angle of 20 counterclockwise from the y axis. Determine the point in the beam at which the maximum tensile flexural stress acts and the magnitude of that stress. P = 3.00 kN P 800 mm 700 mm R R2 Figure P7.16 20%
