The pin-jointed structure below supports the vertical loads as shown, the widths of the framework are 25m and 12.5m as shown in the diagram. 20N 12.5m 40N A R1 B E 25m 45 C R2 D Use a graphical method to illustrate the forces in each member and determine their values and identify each as a strut, tie or redundant member. Determine the reaction forces and use vector diagrams to consider joints A,B,C and D, producing the force and state of each member. Show your answers in a table such as that below. R1 = Member R2 = Graphical Results State Force (Strut/Tie/Redundant)
