Roof trusses used in various applications is an example of * Mechanism Inversion Machine Structure​

Answer 1

Answer:

A truss is essentially a triangulated system of (usually) straight interconnected structural elements; it is sometimes also referred to as an open web girder. The individual elements are connected at nodes; the connections are often assumed to be nominally pinned. The external forces applied to the system and the reactions at the supports are generally applied at the nodes. When all the members and applied forces are in a same plane, the system is a plane or 2D truss.

The principal force in each element in a truss is axial tension or compression.
