A column ABCD supports several loads as shown in Figure 1. Segment AB has an area of 8,000mm2, segment BC has 2,000mm2, and segment CD has an area of 12,000mm2 Determine the axial (normal) stress in each segment and identify if the resulting stress is Tensile Stress or Compressive Stress.

AB has compressive force = stress = (100 + 50 + 100 + 85 + 85) kN / 8000 mm^{2}

BC has force 100+50 + 100 - 85 - 85 - 200 - 200 = -150 kN a tensile force / stress

stress = 150 kN / 2000mm^{2}

CD has force 100+50+100 - 85 - 85 + 200 + 2 00 = 480 kN compressive force stress = 480 kN / 12000 mm^{2}
