A wood beam supports the loads shown. The cross-sectional dimensions of the beam are shown in the second figure. Assume LAB = 2.9 m, LBc = 0.9 m, LcD = 1.1 m, w = 6.7 kN/m, P = 4.2 kN, b₁ = 10 mm, b₂ = 95 mm, d₁= 100 mm, and d₂ = 240 mm. Determine the magnitude of: (a) the maximum horizontal shear stress Tmax in the beam. (b) the maximum tension bending stress max (and location x) in the beam. Answers: (a) Tmax= (b) omax= i i LAB LBC kPa. LCD kPa, at x = i d₁ N b₂ m. d₂

The steel beam has the cross section shown. The beam length is L = 5.6 m, and the cross-sectional dimensions are d = 335 mm, bf = 195 mm, tf = 12 mm, and tw = 10 mm. Calculate the largest intensity of distributed load wo that can be supported by this beam if the allowable bending stress is 165 MPa. Wo X Answer: Wo= 12 B 72 C kN/m

A steel plate 2.5 m x 1.6 m x 100 mm  thick is to be hoisted by a steel cable sling as shown in the figure.  Assume the steel weighs 77.3 kN/cu.m. Determine the shear stress (MPa) in the 16 mm diameter pins through the clevis    The correct answer is 45.33. Show solution.
