A simply supported steel beam of channel-type cross section is loaded by both the uniformly distributed load and the couple shown in the figure. Determine the maximum tensile and compressive stresses. 40 kN/m 40 mm 40 mm 20 kN.m 220 mm- HE T 3 m 1m1 m. 40 mm 200 mm

Question 10 options:   a)  2.10 MPa   b)  1.12 MPa   c)  1.53 MPa   d)  2.92 MPa

Question 2 A truss tower is subjected to the following (unfactored) actions as shown in Figure 2. All supports are assumed to be pinned. Wind load: WL = 5kN Imposed load: IL = 20KN Dead load of the tower transferred to the left-leg: DL₁ = 25kN Dead load of the tower transferred to the right-leg: DLR = 25kN Dead load of the cantilever part (applied at the center of the cantilever pane): DLc = 10kN Calculate the factored design reactions of the foundations for the two legs (i.e., the maximum upward and downward reactions).
