A rigid plate (AC) is connected to flat steel bars by pins at A and B. The horizontal flat steel bar ED is also connected via pins at points E and D. Member AE consists of two 6 mm by 25 mm parallel flat bars, while members EB and ED are single flat bars with dimensions 8 mm by 30 mm. If the structure is subjected to a 2-kip vertical force at point A, find the axial (normal) stress in members AE, EB, and ED. brow A 2 kip -3'- E B D 9. -3'- 4' Figure 3.1: Structure with a plate and steel flat bars.
