It does not use the moment equilibrium equation to solve the problem. Report. They are used to span greater distances and to carry larger loads than can be done effectively by a single beam or column. The chord size and web configuration are determined by span, load and spacing. P-425, the web members BC and EF are perpendicular to the inclined members at their midpoints. Summing moments about a point involves looking at forces that don't go through the point in question and multiplying their distance away from the point by the amount of force perpendicular to a line from the point to the force. Yet again, evaluating the support reaction plays an important role in solving any structural problems. A D C B E Simple Trusses The simplest configuration for a stable truss is a triangle as shown in red above. A truss is a structure that takes advantage of the inherent geometric stability of the triangle to evenly distribute weight and to handle changing tension and compression.
