CHAPTER 4 : STRUCTURE :warning:
METHOD OF JOINTS :check:
Satisfying the conditions of equilibrium for the forces acting on the connecting pin of each joints
Each joint is subjected to a force system that is coplanar and concurrent.
Only 2 independent equilibrium equations are solved :no_entry:
METHOD OF SECTIONS :check:
A truss is divided into two parts by taking an imaginary "CUT" through the truss.
Decide how you need to cut the truss :
Where you need to cut the truss
Where the total number of unknown does not exceed than 3
Decide which side of the cut truss will be easier to work with ( minimize the number of force you habe to find.)
STRUCTURE :red_cross:
Connected systems of members built to support or transfers forces and safely withstands the load applied to it.
TRUSS :star:
The framework composed of members joined at their ends to form a rigid structure
