Generation of the solution to the problems requires determination of the forces involved, writing the equations, and then solving them. To help develop these equations, visual representations known as Free Body Diagrams (FBDs) are used. Formally, a FBD is a diagram of an isolated particle or rigid body which may include body (b) The free-body diagram shows only the external forces acting on the designated system of interest—the person—and is the diagram we use for the solution of the problem. Strategy If the scale at rest is accurate, its reading equals F → p F → p , the magnitude of the force the person exerts downward on it.
