Use Method of Section on Gambrel Truss and Find section Forces - Solved Example


Hi,

Problem:
This is a Gambrel Truss with 5 known load forces on it as shown below. Let's say the reaction forces are already found, at A(0, 959.6 N) and at H(0, 450 N). Each applied load is 300 N.

Use the method of sections to determine all the unknown external forces acting on section ABG. Using your results, list whether members BD, BE, and EG are in compression or tension?



Solution:



Thank you for your kind visit.
