The single overhang beam uses a 4 x 12 S4S Douglas fir member. Determine the maximum bending stress developed. Is it safely designed? (Fb = 1,300 psi). The figure below shows the FBD of the beam with its loading, V and M diagrams, and the finished size of the transverse cross-section of the beam. Select from the choices provided below.

The loaded beam, its FBD, shear force (V), and bending moment (M) diagrams are shown in the figure below. Determine the values of reactions (MB, VB), V and M, and select the right option from the choices provided. Picture8.jpg

The figure illustrates a simply supported beam with overhangs at both ends, including its loading, deflected shape, and a portion of the bending moment diagram. A vertical red line indicates a specific transverse section of the beam where the bending moment diagram crosses zero. At this section, the bending moment is zero, the sign of the bending moment changes, and the deflected shape transitions from concave to convex curvature (or vice versa). Such a section is known as the point of [BLANK-1]. Picture5.jpg
