The table below is a summary of key notations and symbols that will be used throughout the documentation. In general, the force diagrams have the superscript \(\perp\), which signifies that the elements of the force diagram are in perpendicular orientation to the corresponding element in the form diagram (edge to edge in 2D, and face to edge in 3D). The prime symbol (\(\prime\)) is used to signify dual elements or relationships. Any elements or variables that are exclusive to the force diagrams are suffixed with an asterisk (\(*\)).
