One way of distributing a force across a large distance is by building a ''Plane Truss'', which takes advantage of the principle of Equilibrium to translate forces along a system of interconnecting members. | One way of distributing a force across a large distance is by building a ''Plane Truss'', which takes advantage of the principle of Equilibrium to translate forces along a system of interconnecting members. | ||

The simplest truss is a triangle made of three points: '''A''', '''B''' and '''C''', and three members: '''AB''', '''BC''' and '''CA'''. The method of distributing forces amongst many members relies on the engineer's ability to place a ''tensile'' or ''compressive'' force at any particular location. To properly sum forces at a particular point, one must be able to sum forces into that point and also away from it. Thus, '''AB''' and '''AC''' are in compression while '''BC''' is in tension. | The simplest truss is a triangle made of three points: '''A''', '''B''' and '''C''', and three members: '''AB''', '''BC''' and '''CA'''.
