What does a free-body diagram show?
A free body diagram models the forces acting on an object. The object or ‘body’ is usually shown as a box or a dot. The forces are shown as thin arrows pointing away from the centre of the box or dot.
What is free-body diagram explain with example?
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 that were discussed in an earlier unit.
What information is needed to draw a free-body diagram?
To draw a free-body diagram, we draw the object of interest, draw all forces acting on that object, and resolve all force vectors into x– and y-components. We must draw a separate free-body diagram for each object in the problem.
What are the 5 steps to drawing a free body diagram?
You can draw a free-body diagram of an object following these 3 steps: Sketch what is happening….Let’s go through these steps in more detail.
- Step 1: Sketch what is happening.
- Step 2: Determine the forces that act on the object.
- Step 3: Draw the object in isolation with the forces that act on it.
Is weight included in free body diagram?
The free body diagram for a block of cheese resting on a table has normal force N up, weight W down, and no acceleration.
How is work done calculated?
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.
Why do we use free body diagram?
Free body diagrams are used to visualize forces and momentum applied to a body and to calculate reactions in mechanics problems. These diagrams are frequently used both to determine the loading of individual structural components and to calculate internal forces within a structure.
What does R stand for in free body diagram?
R -> Contact force between table and book. (2) Free body diagram for a object slowing down with friction on a horizontal floor. mg -> Weight of the book. R -> Contact force between table and book. f -> Friction force between the object and horizontal floor.
What is the first step in drawing a free body diagram?
You can draw a free-body diagram of an object following these 3 steps:
- Sketch what is happening.
- Determine the forces that act on the object.
- Draw the object in isolation with the forces that act on it.
Where can I get free auto repair diagrams?

What to do with a free body diagram?
Convert the free-body diagram into a more detailed diagram showing the x – and y -components of a given force (this is often helpful when solving a problem using Newton’s first or second law). In this case, place a squiggly line through the original vector to show that it is no longer in play—it has been replaced by its x – and y -components.
