Question

The wood beam supports loads of w - 440 lb/ft and P - 840 lb on span lengths of Lap - 11.6 ft, Loc - 5.8 ft, and Lco- 5.8 ft. The beam
cross section has dimensions of bj - 1.3 in., dj - 3.9 in., by - 4.8 in, and dy - 9.85 in. Determine the magnitude and location of:
(a) the maximum horizontal shear stress in the beam.
(b) the maximum tensile bending stress in the beam.

The wood beam supports loads of w = 440 Ib/ft and P = 840 Ib on span lengths of LAB = 11.6 ft, LBC = 5.8 ft, and LcD= 5.8 ft. The beam
cross section has dimensions of b1 = 1.3 in., d1 = 3.9 in., b2 = 4.8 in., and d2 = 9.85 in. Determine the magnitude and location of:
(a) the maximum horizontal shear stress in the beam.
(b) the maximum tensile bending stress in the beam.
