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.

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.

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
A truss is a diagonal brace which provides structural support for a bridge span by extending between a vertical member and the bridge span.
"The queenpost truss, sometimes queen post or queenspost, is similar to a king post truss in that the outer supports are angled towards the center of the structure. The primary difference is the horizontal extension at the center which relies on beam action to provide mechanical stability. This truss style is only suitable for relatively short spans" coveredbridgesite.com
An open-frame N-truss without diagonal members, with rigid joints between the top and bottom chords and the verticals. Known also as open-frame truss or vierendeel truss.
This means that the triangles are under, not on top This means that the triangles are not on top, yet they are under the structure. Search Under truss adn get a picture, then search over truss adn you will is the difference
