For equilibrium the normal forces acts in which direction in the free ...
As the loads are being acting in the downward direction. Thus to make the forces balance, the normal forces act in the vertically upward direction. As we know that when there is no lubricating fluid present between the surfaces in contact, the dry friction occurs. This friction magnitude is taken out from these normal forces.

Normal Force Direction in Free Body Diagrams for Friction Calculations
In free body diagrams used for friction calculations, the normal force acts vertically upward. This is because the normal force is the force exerted by a surface to support the weight of an object resting on it. When an object is placed on a surface, the surface exerts an equal and opposite force to counteract the weight of the object and prevent it from sinking through the surface.
Explanation:
- Normal Force: The normal force is always perpendicular to the surface on which the object rests. In the case of friction calculations, the normal force is crucial as it determines the force with which the object is pressing against the surface.
- Friction: Friction is a force that opposes the relative motion or tendency of such motion of two surfaces in contact. The normal force plays a significant role in determining the frictional force between the object and the surface.
- Vertical Upward Direction: In free body diagrams for friction calculations, the normal force is depicted as acting vertically upward because it counteracts the weight of the object and supports it against gravity. This vertical upward normal force is essential for calculating the frictional force accurately.
In conclusion, when constructing free body diagrams for friction calculations, it is important to show the normal force acting vertically upward to accurately determine the frictional forces involved in the system. Understanding the direction of the normal force is crucial for analyzing the forces at play in equilibrium situations.
