When a number of forces acts on a body, or group of bodies, they form a system of forces or force system. Depending upon the orientation of forces acting on a body the system of forces will be classified as: (i) Coplanar Force System: When lines of action of all...
Truss may be defined as a structure made up of several bars joined together at their ends. These bars which are made up of angles or channel sections are called members of the truss. Various members of a truss are joined together byriveting, welding or by nuts and bolts. However,...
A body in equilibrium is subjected to a number of external forces and reactive forces, provided by the supports. The equilibrium of such bodies may be considered by removing the supports and replacing them by reactions, which they exert on the body. The body so isolated from the system is...
If a number of forces are acting simultaneously on a particle, it is possible to find out a single force which could replace them i.e. which would produce the same effect as produced by all the given forces. This single force is called resultant force. This resultant force, causes the...
