Example 2 The simple truss shown supports the two loads, each of magnitude L. Deter- mine the forces in members DE, DF, DG, and CD. A B 2R H R α = 22.5° a L D E L

Please answer tbis question. What is the force in member BC.

Find the support reactions.  Determine the force in each member of the truss.  Draw a summary diagram clearly showing your results. Be sure to identify any zero force members in the summary diagram.

Question 2: Find the force acting on members AC, BC, and BD of the truss. Specify if the forces are either tensile or compression forces as shown below. t. 10 m 10 m - 10 m 6 m 15° x2 6 m 6 m 40 kN C. 50 kN 6 m B. to

3) A cantilevered truss is loaded as shown to the left. First, determine the support reactions. Second, using method of sections determine the force in member 6 kN 1.2 m В 1.2 m A AB. Specify tension (T) or compression (C). Ans: Ax = 16 kN (), C = 16 kN (→), A, = 9 N (1), FAB = 4 kN (T) 3 kN 0.9 m %3D %3D C D

Consider the frame shown in (Figure 1). The load F1 = 620 N is applied to the pin. Determine the x and y components of force which pin C exerts on member ABC using scalar notation.
