An exclusive construction video tutorial to find a zero force member in a truss
This construction video is created by Jeff Hanson to show you how to discover a zero force member for trusses in method of joints system.
Trusses are used to support roof, strengthen bridges, or support towers. In this article we will learn how to analyze a truss.
A truss belongs to one of the most important types of engineering structures and is specifically applied in designing the bridges and buildings. Trusses are developed for sustaining loads. A truss is generally built with long, straight members associated with joints at the end of each member.
A truss should be analyzed properly as while going to design truss members, and its joints in a perfect manner, one should contain transparent knowledge concerning what load is transferred by each members of the truss, under a specified loading condition.
The method of joints is considered as one of the most recognized methods for finding out the unidentified forces functioning on the individual members of a truss. The fundamental perception of method of joints is that, as the truss remains in equilibrium, each joint in truss will also remain in equilibrium. All forces functioning on a joint must add to zero.
