A truss is a prefabricated piece of frame work that is installed at the site, but actually assembled somewhere else. A rigid framework, as of wooden beams or metal bars, designed to support a structure, such as a roof. A rafter on the other hand, is a single piece of wood, usually a 2x4, that is part of the supporting structure of a roof that is built on site.

The upper member of a truss system that acts as a common rafter is typically referred to as the "top chord." It is the horizontal or sloped structural element that supports the roof load and connects the apex of the truss to its endpoints. The top chord works in tension or compression, depending on the design and loading conditions, and contributes to the overall stability and strength of the truss structure.
They each have their place, but on the same style roof, trusses would be stronger.
In plane truss, both the truss structure and the applied loads lie in the same plane. In space truss, either the structure or the loads or both lie in different planes.
To cut a bird's mouth when constructing a roof truss, use a saw to create a notch in the bottom of the rafter where it meets the top plate of the wall. This notch allows the rafter to sit securely on the wall and provide support for the roof structure.

A truss is the triangler wood frame work for a roof. Rafters are the singular peices of wood put between them That make up the begining of the celing
A truss is the structure that holds the roof(or bridge or whatever). Purlins are members holding a few trusses together. A truss is a simple frame made from two force members.
Truss can carry only vertical loads or axial loads. It depends upon structure. But Beams can carry vertical loads and moments
it is a hybrid between an arch bridge and truss bridge. so it is classified as an arch and truss
In construction, a joist is a horizontal structural element that supports the floor or ceiling, while a rafter is a sloped structural element that supports the roof. Joists are typically found in floors and ceilings, while rafters are found in roofs.
A roof joist is a horizontal beam that supports the ceiling, while a rafter is a sloped beam that supports the roof. Joists are typically found in the horizontal plane, while rafters are angled to support the roof's pitch.
