In physics, mass is a property of a physical body. It is generally the amount of matter of an object. It is determined by the strength of its mutual gravitational attraction to other bodies, its resistance to being accelerated by a force, and in the theory of relativity gives the mass–energy content of a system.

A force that tends to shorten or squeeze something, decreasing its volume.

Span is the distance between two intermediate supports for a structure, e.g. a beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of antennas or for aerial tramways.

The main forces in a suspension bridge of any type are tension in the cables and compression in the pillars.
