Force System
When a member of forces simultaneously acting on the body, it is known as force system. A force system is a collection of forces acting at specified locations. Thus, the set of forces can be shown on any free body diagram makes-up a force system.
Truss
It is a rigid structure composed of number of straight members pin jointed to each other. It can sustain static or dynamic load without any relative motion to each other.
Types of Truss
1. Plane Truss It is defined as a truss in which members are essentially lies in a single plane.
2.Rigid Truss Rigid means there is no deformation take place due to internal strain in members.
3.Simple Truss This type of trusses built a basic triangle by adding different members are known as simple truss.
Classification of a Truss (based on joints)
Truss can be classified on the basis of joints(1) and members (m) in the structure. It can be easily understood with the help of following hierarchical approach.
