In the given cross section, the neutral axis relative to the bottom fiber is 63 mm and the moment of inertia with respect to the neutral axis is 30,950 mm4. Shear force is 13 kN and bending moment is -120 N-m. Determine the: Total tensile force on the cross-section (kN)

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

The initial compressive force of a steel column can be determined by Euler's buckling formula. The column has the following properties: A = 9484 mm² Fy=345 MPa x = 164 x 106 mm4 ly = 23 x 106 mm4 Proportional limit, fs = 290 MPa The x-axis has an unbraced length of 10 m which is pinned at the top and fixed at the bottom with an k = 0.70. The y-axis has unbraced length of 5 m due to the bracing at the mid-height. Compute the initial compressive load of the column. Select the correct response: 6606.59 KN 3706.14 KN E = 200 GPa 1816.01 kN 926.53 kN
