A flanged wooden shape is used to support the loads shown on the beam. The dimensions of the shape are shown in the second figure. Assume $L_{AB} = 6$ ft, $L_{BC} = 2$ ft, $L_{CD} = 3$ ft, $L_{DE} = 3$ ft, $P_C = 1740$ lb, $P_E = 2040$ lb, $W_{AB} = 890$ lb/ft, $b_1 = 12$ in., $b_2 = 2$ in., $b_3 = 8$ in., $d_1 = 2$ in., $d_2 = 11$ in., $d_3 = 2$ in. Consider the entire 14-ft length of the beam and determine:
(a) the maximum tension bending stress $\sigma_T$ at any location along the beam, and
(b) the maximum compression bending stress $\sigma_C$ at any location along the beam.
Answers:
(a) $\sigma_T = $ psi.
(b) $\sigma_C = $ psi.
