The cross-section of the two wooden members is a rectangle with a = 120 mm and b= 60. They are joined by a simple glued joint as shown. Knowing that P = 9 kN, determine the normal and shear stresses at the joint when (a) a = 30°, (b) a = 45°.

X Incorrect Three plates are welded together to form the section shown. Dimensions of the cross section are b = 3.6 in., d = 10.8 in., a = 2.3 in., and t= 0.4 in. For a vertical shear force of V = 39 kips, determine the shear flow through the welded surface at B. d В Answer: i 1.283 kip/in.

Three plates are welded together to form the section shown. Dimensions of the cross section are b = 4.7 in., d = 14.1 in., a = 3.7 in., and t= 0.8 in. For a vertical shear force of V = 46 kips, determine the shear flow through the welded surface at B. d В b. Answer: kip/in.

The two vertical steel [E = 200 GPa] rods that support rigid bar ABCD are initially free of stress. Rod (1) has an area of A₁ = 350 mm² and a length of L₁ = 2.1 m. Rod (2) has an area of A₂ = 375 mm² and a length of L₂ = 1.5 m. Assume dimensions of a = 3.2 m, b = 1.1 m, and c = 1.4 m. After a load of P = 130 kN is applied to the rigid bar at D, determine: (a) the normal stresses in rods (1) and (2) (b) the magnitude of the downward deflection of the rigid bar at D. y,v (2) a L2 Rigid bar L₁ Answer: (a) σ₁ = i 02= i (b) VD= i (1) B MPa MPa mm -X,U b C ↓ С D P
