Question
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 LAB = 5 ft, LBC = 2 ft, LCD = 4 ft, LDE = 2 ft, Pc= 2060 lb, PE = 1950 lb, WAB = 860
lb/ft, b1= 12 in., b2= 2 in., b3= 7 in., d1 = 2 in., d2 = 10 in., d3 = 2 in. Consider the entire 13-ft length of the beam
and determine:
(a) the maximum tension bending stress or at any location along the beam, and
(b) the maximum compression bending stress c at any location along the beam.
