Extracted text: A wood beam ABC with simple supports at A and Band an overhang BC has height h = 350 mm (see figure). The length of the main span of the beam is L = 3.3 m and the length of the overhang is - = 1.1 m. The beam supports a concentrated load 3P = 18 kN at the midpoint of the main span and a moment PL = 9.9 kN · m at the free end of the overhang. The wood has weight density y = 5.1 kN/m³ L. M%3D h= 350 mm BA (a) Determine the required width b of the beam based upon an allowable bending stress of 8.2 MPa. Round to one decimal place. mm (b) Determine the required width based upon an allowable shear stress of 0.7 MPa. Round to one decimal place. mm
