## What Is Truss?

A truss is a structure consisting of various members arranged in rectangles, squares, triangles—the various members attached to the truss act as one object. Trusses are commonly used in railways, bridges, roofs, and towers.

The member of the truss feels compression load, dead load, and live load. Now the part of the truss that feels pressure in the member is usually called the strut. Similarly, the truss part in which the member is carrying a dead load and live load is called a tie member.

The truss is expensive to use. It is often more economical where there is a long span. Each member of the truss can be easily inspected. The repair work of the truss can be done easily. Using a truss-like North light keeps the air fresh.

Compression force and tension forces are generated in each member of the truss. Therefore compression force and tension force should be calculated for each member of the truss.

## Methods to Find Stresses in the Members of Truss

The forces generated in the member of the truss can be found in the following way.

- Method of joint
- Graphical method
- Method of section

### Method of Joint

The method of joints is the process used to resolve the various forces applied to different truss members. This method focuses on the joints between the members. And the fastest and easiest way to calculate all the unknown forces in a truss structure.
