How to recognize whether a truss is perfect or not
This construction video provides detailed information on how to choose perfect trusses for building structure.
In engineering term, a truss is known as a structure that comprises of two-force members only. Here the members are arranged in such a way that the assemblage performs as a single object.
A "two-force member" stands for a structural component where force is employed to only two points.
The perfectness of a truss depends on the equation given below :-
2j – 3 = n
Here j stands for number of joints and n represents number of members.
Besides, if the structure is built up with members which are just adequate to maintain the structure in equilibrium once loaded devoid of any modification of shape.
