Diagram the forces acting on the combination of gymnast and bar. The bar is supported by two ropes that attach to the ceiling. A gymnast holding onto a bar, is suspended motionless in mid-air. A free-body diagram for this situation looks like this:Ģ. Continue to review the the list of forces and their description and this page in order to gain a comfort with constructing free-body diagrams.ġ. If you have difficulty drawing free-body diagrams, then you ought to be concerned. See answer.Īnswers to the above exercise are shown here. Neglect air resistance. Diagram the forces acting upon the car.

Objects do not necessarily always have four forces acting upon them. T he free-body diagram above depicts four forces acting upon the object.

An example of a free-body diagram is shown at the right It is generally customary in a free-body diagram to represent the object by a box and to draw the force arrow from the center of the box outward in the direction that the force is acting. Each force arrow in the diagram is labeled to indicate the exact type of force. The direction of the arrow shows the direction that the force is acting. The size of the arrow in a free-body diagram reflects the magnitude of the force. These diagrams will be used throughout our study of physics.

A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation.
