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
Truss can carry only vertical loads or axial loads. It depends upon structure. But Beams can carry vertical loads and moments
Each roof truss is structurally designed for a particular situation. Where a truss overhangs or extends beyond a supporting wall, so that the truss is partly cantilevered (e.g. in a deep eave), the calculations by the truss designer will take this into account.
cutting rafters
In some dialects, "trust."
To a limited degree, yes. However, very strong tornadoes will destroy just about any structure they hit, including truss bridges.
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.
giant cables and abutments
Yes. Talk to your local lumber yard and truss designer. $$$
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.

A ridge board doesn't support rafters of the bridge whereas a ridge beam does.
it is a hybrid between an arch bridge and truss bridge. so it is classified as an arch and truss
Most sloped roofs are supported by a purlin bracing system. A board the same size as or larger than that of the rafters is placed on edge perpendicular to the rafters and attached on the bottom side of the rafters. Legs are then placed under the purlin brace and with the top notched under the purlin and the bottom placed on and attached to the top of a wall, thus transferring the weight of the roof from the rafters to the top of the walls.
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
