Question 15 20 pts Use method of sections or method of joints to solve for the following unknowns on the truss system shown in figure 2 below. For tensile members, use A = 500 mm and for compressive members use A = 400 mm Use a = 20.2 kN.b = 24.1 kN. 2.1 Axial stress in member CB in MPa. Indicate negative if compressive stress. (10 pts) IN 4. FIND, a) Axial stress in member CB in MPa b)Axial stress in member CD in MPa SEN FIGURE 2
