Answer:
Free-body diagrams are defined as the diagram that represents the direction and magnitude of all forces that act on an object.
There are some limitations of the free-body diagrams, that are:
- The free-body diagram is based on coordinate system that increases the complexity of the diagram.
- There are lot of forces acting on an object such as friction, gravity, drag, tension, and normal force and to calculate the end result, it is important to determine the correct direction of all the forces otherwise wrong direction of any one of the force can give the wrong answer.
- Free-body diagrams do not depend on the size and shape of the body, that is why unable to calculate the rotation and torque.
