Q2. Determine the stress in each section of the bar shown in Fig. below, when subjected to an axial tensile load of 20 kN. The central section is 30 mm square cross-section; the other portions are of circular section, their diameters being indicated. What will be the total extension of the bar? For the bar material E = 210GN/m². (3) -250 100 400 20 kN 2 20 kN T 20 30 15 Q2. Determine the stress in each section of the bar shown in Fig. below, when subjected to an axial tensile load of 20 kN.
