Unformatted text preview: shape are shown in Fig. b. Consider the entire 18-ft length of the beam and determine: (a) the maximum tension bending stress at any location along the beam, and (b) the maximum compression bending stress at any location along the beam. 8.50 Two steel plates, each 4 in. wide and 0.25 in. thick, reinforce a wood beam that is 3 in. wide and 8 in. deep. The steel plates are attached to the vertical sides of the wood beam in a position such that the composite shape is symmetric about the z axis, as shown in the sketch of the beam cross section. Determine the maximum bending stresses produced in both the wood and the steel if a bending moment of Mz = +50 kip-in is applied about the z axis. Assume E wood = 2,000 ksi and E steel = 30,000 ksi. For practice 8.17 8.36 8.45...
