Uniformly distributed force is applied on the bar AC in the downward direction with magnitude (100 +x) KN/m. All members have circular cross section. All pins (indicated as red in the figure) are in single shear and have diameters of 40 mm. Calculate the shear stress in pin A and the maximum normal stress in member BD. Note: For boundary condition, point A is pin joint and point E is roller support. (100+x) kN/m T 3m A I 100mm B 50mm 50mm -2.5m. 2.5m
