![]() ![]() The diagram thus obtained is called a free body diagram. These are called mutual interaction forces (one of this type we have seen in the illustration of IIIrd law) and show all possible acceleration. Now separate them from others by cutting the string contacts (sort of imaginary separation) In effect, make them free (that's where comes the name free body) from other components and at the same time show all the forces acting on it, external as well as internal, arising due to separation from other parts. acceleration, velocity.Ĭoming to actual situation one should first identify all the component involved in the system, say mass m 1, mass m 2 ., pulley 1, pulley 2, etc. ![]() Now each system is ready to get treatment of laws of motion e.g. By all forces we mean external as well as internal forces (internal forces refer to mutual reactions). Whenever one attempts a problem involving forces and acceleration (say of dynamics or statics) one must show all forces and acceleration (possible acceleration may be unknown also) on each part of the system treating that part separately (it is called dividing system into possible subsystems). It is to be noticed here that during previous examples, we were using a concept called FBD implicitly which can now be brought to you conscious attention.
