A planar truss is the one whose all members lies in a single plane. If a plane truss does not change its shape when loaded then it is known as Rigid Planar Truss.

2. Definition and basic points A truss is a structure of straight, long , slender members joined at end points In planar truss all of its members lie in the same plane Roofs and bridges consists of parallel planar truss Members can be joined together by a number of ways such as welding, riveting, bolting etc There are certain assumptions which are made to analyze a truss

3. TENSION & COMPRESSION The force which tends to elongate i.e. increase in the length of the member of truss is known as tension or tensile force. Tensile force acting on a member is as shown below: The force which tends to compress the member i.e. tries to reduce the length of a member in truss is known as compression or compressive force. Compressive force acting on a member is as shown below:
