Answer the following question in 3-4 complete sentences.

Answer:

A truss is a structure made up of one or more triangular units that are connected at the joints by long beams. The triangles of a truss structure keep the structure from sheering and collapsing. A suspension is a type of bridge where the main load-bearing elements are hung from suspension cables. The load is distributed to the cables, which continue beyond the structure. Both types of construction are most commonly used in bridge building.
