Example1. Figure 1 shows a frame that is simply supported at A

Example1. Figure 1 shows a frame that is simply supported at A and B. Two forces act on it. The material in the rods is a linear spring material with spring modulus E=200 GPa. All the bars have the same cross-sectional area, A=1500 mm2.pi 6 m 50 kN 30 A D 60 kN 4 m 6 m 12 m B 14 m picture 1 1.1 Determine the basic forces in A and B 1.2 Determine all the bar forces. 1.3 Determine the normal stress, normal stress and elongation/shortening of the bar DB.
