Question

How to understand free body diagrams easy way in strength of material?

Answer 1

In many problems in engineering mechanics, it is essential to isolate the body under consideration from the other bodies in contact and draw all the forces acting on the body. For this, first the body is drawn and then applied forces, self-weight and the reactions at the points of contact with other bodies are drawn. Such a diagram of the body in which the body under consideration is freed from all the contact surfaces and shows all the forces acting on it, is called a Free Body Diagram (FBD).
