2. Given: Truss with the loads and reactions as shown.
Find: The forces in members BD, CD, and CE using the method of sections.
Then use a combination of methods to solve for the forces DF and EG
Hint: Moments use perpendicular distances. Hint: The sianted forces can be taken as
moments about G without resolving into X or Y components to solve for reactions.
