A. 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 mm2and for compressive
members use A = 400 mm2.
Use a = 24.7 kN, b = 14.0 kN,
2.1 Axial stress in member CB in MPa. Indicate
negative if compressive stress.
B. Use method of sections or method of joints to solve for the

2.2 Axial stress in member CD in MPa. Indicate
negative if compressive stress.
