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.)
Connected systems of members built to support or transfers forces and safely withstands the load applied to it.
The framework composed of members joined at their ends to form a rigid structure
TYPE OF TRUSSES
(5) CAMBERED FANK
(9) FLAT WARREN
