I can represent the problem when i come back; you can get springs where the force only vary from 1 till 2%; and where it is sliding i will use a surface finish on 0,3; but i have not found a table who tells the relationship between surface finish and the coefficient for friction, but my guess is...
Am i rigth or not? i should add this is no homework it is for a real welding fixture; i can explain by pm if someone r interested. The problem definition is relevant as defined.
My question is as stated above:

There r gearing too; with 30 degree we get the following relationship:
y-> 0,5...
Hi i think i get it now; The force F1 i wrote about do no not act on the plunger, that so explains it; i can also see that on you free body diagram and understand it by intution. It was nice to get that problem out of the way :).
That changes the problem definition-> i will no see it was a...
I will look deeper into your reply in this week hopefully tomorrow. You say that there r more who r acting on it then the friction force; that is what has confused me.
Because the force of the springs acts in the x direction, so who can it create a force in the y direction; let me illustrate...
About the friction force; it is equilibrium on the x direction; because the two friction forces in the right and left case are countering each other, in the x-direction.
I am just interested in the force in the y-direction; so the only force who is interesting is the friction force in the...

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?
Homework Statement
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...
I want to point out that this is not a Homework or Coursework question. in wiki we can read the following under the chapter intution:

I have a case where I am trying to find the optimal place to put 3 rivet points (I will maybe even test with 4). The rivet points r subject to a force according to the picture, which vary 360. What I am seeking here is mathematical methods to find the optimal place to put the 3 riverts, so that...
Problem understanding "Thévenins equivalent circuit "
The problem is illustrated in the picture below.

I am not sure i understand this so well either, any comments are appriciated.

Yes but above that box, it is a box that says material id, which means that i give a friction coefficient for both materials, which hardly is the same as the relative friction between two surfaces
Kindly Pellefant ...
When you have friction between two surfaces, then u use the relative friction coefficient right. But how do i do that with ansys? I have put contact element between two different materials, but it doesn’t seems as I can use the relative friction in ansys. ...
This is the possibilities i seems...
