False

Explanation:

Free Body Diagrams:
Free body diagrams are used to represent the external forces acting on a body or a system. These diagrams are used to analyze the equilibrium of the body or system by considering the forces and their directions. In a free body diagram, all forces acting on the body are represented by vectors. These forces can include both translational forces (such as applied loads, reactions, etc.) and rotational moments (such as torques).

Internal Forces:
Internal forces are forces that exist within a body or a system. These forces are not visible from the outside and are responsible for maintaining the equilibrium of the body. When analyzing internal forces using the method of sections, a section is cut through the body or system to isolate a portion of it. The internal forces at the cut section are then evaluated to determine their magnitude, direction, and type (such as tension, compression, shear, etc.).

Rotational Moments:
Rotational moments, also known as torques, are forces that cause an object to rotate about an axis. These moments are typically caused by external forces acting at a distance from the axis of rotation. Rotational moments are important in analyzing the equilibrium of a body or system, especially when considering the rotational motion.

Importance of Rotational Moments:
Rotational moments are essential in analyzing the equilibrium of a body or system. They play a crucial role in determining the stability, balance, and motion of the body. Ignoring rotational moments in free body diagrams or the evaluation of internal forces by the method of sections can lead to incorrect results and an incomplete understanding of the system's behavior.

Conclusion:
In conclusion, rotational moments are indeed counted in free body diagrams and the evaluation of internal forces by the method of sections. These moments are essential in analyzing the equilibrium and motion of a body or system. Therefore, the statement "Rotational moments are not counted in the free body diagrams and the evaluation of the internal forces by the method of sections" is false.
