What are trusses, Static Structure, Hypostatic Structure, and Hyperstatic Structure?

Trusses are structures made up of slender elements that are connected to each other at the ends in order to transmit tensile and compressive forces.
Considering their spatial arrangement, trusses can be flat or spatial, depending on whether their bars and external forces are in the same plane or not.
Static Truss Structure: characterized by being stable, having equilibrium, and not having movement. Its number of support reactions is usually equal to the number of equilibrium equations.
Hypostatic Truss Structure: its classification as hypostatic is due to the fact that the number of equilibrium equations is greater than the number of unknowns. Thus, it is said that the truss will collapse. A truss may be unstable even if it is statically determined or indeterminate.
Hyperstatic Truss Structure: a truss is hyperstatic when the application of equilibrium equations is insufficient to determine the support reactions and the forces in the bars.
