1. The problem statement, all variables and given/known data

The statement i make is that detail 2 will never move in the x-direction if the friction is cero. Because the force who acts on detail 2 acts in the y-direction and not in the x-direction. If we have friction we will get a force who acts in the x-direction. See picture

2. Relevant equations

Normal equilibrium equations

3. The attempt at a solution

No solution i wonder if my statement is correct.

Anyone? The reason for the question is that it dosen't seems natural; but that is what i get; because how could a force in the x-direction eb created if we don't have friction?

The normal force Detail 1 exerts on Detail 2 DOES have an x-component.
