QUESTION:
The truss supports the vertical load of 600 N. Determine the force in members BC , BG , and HG as the dimension L varies. Plot the results of F (ordinate with tension as positive) versus L (abscissa) for 0 L 3 m .
ANSWER:Step 1 of 6
Section a-a shown in the below F.B.D has been chosen since it cuts through the three members and whose forces are to be determined.
The member is considered in tension if the force is "going" away from the joint and in compression if the force is "going" towards the joint.
For the analysis, the right portion of the sectioned truss will be used so that there is no need to calculate the external support reactions at and I.
