A simple force analysis

How can we calculate the normal force F1 acting on this part along its axis? Some say it equals F÷cos30°, while others say it equals F×cos30°. Which one should be used?

Of course, it’s by multiplication – it’s a very simple stress decomposition
Right triangle, F is the hypotenuse, F1 is a leg
F1 and F2 should be perpendicular.
F generates two component forces: one perpendicular to the surface of the object, and the other along the surface of the object. Could the component forces be greater than the resultant force?
What they mean is to apply a horizontal force
The two component forces are perpendicular to each other. It can only be divided into two forces: one perpendicular to the slope and one parallel to the slope. So what about the force in the horizontal direction?
Just remember that F is the resultant force, while F1 and F2 are the component forces. The two forces act perpendicularly to the surface and parallel to the surface, respectively.
