Civil Engineering Tutorial - Truss Analysis | Method of Sections

Method of sections is a powerful tool to determine forces in statically determinate plane trusses. Cosider this problem, if you want to determine load in blue member, using method of joint you have to proceed in following manner from one joint to another joint. In short you have to analyze 5 joints to determine force in a member.

 

So, you have to solve for ten equations. But using method of sections, just by solving three equations we can solve load in any truss member. That's the power of method of sections.
