The truss in Fig. is pinned to the wall at point F, and supported by a roller at point C. Calculate the force (tension or compression) in members BC, BE, and DE. (Select all that apply)

3. The planar truss below is supported by a pin joint at G and a roller at E. Determine the forces in members AB and AF using Method of Joints (MOJ). Determine the forces in members CD, CE, and EF using Method of Sections (MOS). State whether each member is in tension (T) or compression (C). Please put your final answers in the table provided. 2 m A G 2 m B F 2 m 3 kN E -2 m- D. 2 kN 3 m Member AB AF CD CE EF Force (kN) T/C

3 The figure shows a plana that is held in static equilibrium by two supports at joints A and G. The truss members have negligible masses. Members AB, BC, CD, and GF are oriented horizontally, and the members AG, BF, and CE are oriented vertically. The 20 kN load is oriented vertically and the 30 kN load is oriented horizontally. Calculate the forces in the following truss members and state if they are in tension or compression: a. Member AB b. Member BF mamo c. Member FE org d. Member CE e.

Calculate the force in member GH of the truss and indicate whether it is in tension or compression, using either method of joints or method of sections. Required: Draw the FBD(s) as needed for analysis-all equilibrium equations must correspond to a FBD that you have drawn. Make sure to clearly indicate which FBD your equation(s) correspond to.
