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.

For equilibrium the normal forces acts in which direction in the free ...
The normal force is a contact force that acts perpendicular to the surface of an object. It arises due to the interaction between two surfaces in contact with each other. In the context of free body diagrams, the normal force represents the force exerted by a surface to support the weight of an object resting on it.
Explanation:
The normal force is always directed perpendicular to the surface of contact. It acts in a direction that is away from the surface, pushing against the object to prevent it from sinking into or passing through the surface. In the case of equilibrium, the normal force and the weight of the object are equal in magnitude but opposite in direction, resulting in a net force of zero.
- The normal force is always directed vertically upward in the free body diagrams.
- It acts in the opposite direction to the force of gravity.
- It counteracts the weight of the object to keep it in equilibrium.
- The normal force is exerted by the surface, and it is transmitted through the object to maintain stability.
- If the object is on a horizontal surface, the normal force acts vertically upward, perpendicular to the surface.
- The normal force can also act at an angle if the object is on an inclined plane, but it still acts perpendicular to the surface at the point of contact.
- In a vertical free body diagram, the normal force acts upward while the weight force acts downward.
- When the object is in equilibrium, the normal force is equal in magnitude and opposite in direction to the weight force, resulting in a net force of zero.
Conclusion:
In conclusion, the normal force in a free body diagram always acts vertically upward. It is a contact force exerted by a surface to support the weight of an object. The normal force is crucial in maintaining equilibrium and preventing objects from sinking into or passing through surfaces.
