Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation.
A free-body diagram is a special example of the vector diagrams discussed in Unit 1; these diagrams will be used throughout your study of physics.
It is 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 in which the force is acting.

If the magnitude is subsequently solved to be negative then that implies that the force was assumed to be acting in the wrong direction on the free body diagram and that arrow should be reversed.
Each must be handled properly when interpreting what type of force they cause to act on the particle and how they should be indicated on the free body diagram.

According to an inventive aspect as set forth in claim 20, the automatic shampoo machine of any of claims 14 to 19 further comprises a warm water reservoir tank for storing warm water for use as the cleaning water, wherein the warm water reservoir tank is positioned between the basin and the seat.
In general, where the back-rest of the seat is reclined for the shampooing, the back-rest is adapted to be inclined in an angular range of not greater than a predetermined angle (e.g., 35 degrees) with respect to a horizontal axis.
With the inventive arrangement, this free space is advantageously utilized for the provision of the warm water reservoir tank.

It is convenient, when we use the second law, to draw a free-body diagram--that is, a diagram in which we isolate the body, perhaps by drawing a dashed curve round it (our artist has laid a patch of color over it)--and draw vectors representing all the external forces acting on it.
In Figure 24.9 the block is drawn with three vectors on it: W, the weight, which is the gravitational pull of the earth on the block; R, the force of reaction of the table on the block; F, the pull exerted by the cord connecting the block and the spring balance.

A free body diagram is a graphic, symbolic representation of the body (structure, element or piece of an element) with all connecting "parts" removed.
Free body diagrams may not seem necessary in the relatively simple current applications, but as problems become more complex, their usefulness increases.
This is a Free Body Diagram of these three systems which has been drawn to represent the force system.

 What are Free Body Diagrams?
Next, cut the beam free from the wall and replace the wall with the forces that were supporting the beam at the wall before it was cut free.
The internal forces in the beam before it was cut free from its support are also determined when the forces which will keep, or put, the FBD in equilibrium are found.
It seems to have feet at the bottom of each "leg" that provide the "footing." The free body diagram is drawn passing through the center of gravity of the section.

 The Free Body Diagram
The FBD on the right is perhaps a rather extreme example of a ``simplified sketch'' but it does serve the purpose, which is to show just the object in question and the forces acting on it from outside.
Having done this in our imagination, it is usually wise to actually draw a little sketch of ``the body'' isolated from the rest of the world; it needn't be a good sketch, just a blob of approximately the right shape so we know what we are talking about.
Then we draw in each of the vector forces acting on the body from other entities in the outside world; forces are always pictured as little arrows pointing in the direction of application of the force.

 Equilibrium for rigid bodies
Free-Body Diagram: A diagram of a body (or a part of it) which shows all the forces and couples applied on it, and which has all the forces and couples labeled for use in the solution of the problem is called a free-body diagram.
Composite bodies and internal forces: Forces and couples which are a result of interaction between one part of an object and another part of it will not appear in the free-body diagram of the whole object.
Remember that for each way in which a support restricts the free motion of the body, a force or a moment must be applied to the body to impose the restriction on the motion.

 Free-Body Diagram
A free-body diagram is a sketch of an object of interest with all the surrounding objects stripped away and all of the forces acting on the body shown.
The drawing of a free-body diagram is an important step in the solving of mechanics problems since it helps to visualize all the forces acting on a single object.

 SparkNotes: Applying Newton's Three Laws: The Normal Force
The normal force comes into play any time two bodies are in direct contact with one another, and always acts perpendicular to the body that applies the force.
The normal force thus has equal magnitude and opposite direction of the component of the gravitational force that is perpendicular to the inclined plane.
Using a free body diagram, all of these forces can be displayed, and the resultant motion can be predicted:

 Free Body Diagram / Kinetic Diagram   (Site not responding. Last check: )
For statics problems the sum of the external forces on a particle is zero and so the free body diagram just shows the particle being considered with all it's external forces acting on it.
Although it may be possible to solve simple problems by inspection, only by seeing numerous examples of how both free body diagrams and kinetic diagrams are constructed, will the student have the confidence to tackle much harder problems.
It is extremely important to have both diagrams for all problems so that students can learn to draw these for easy problems and then have a method that they can use for any problem regardless of the difficulty.
