sliding door shifting on wedges

[gtemp]

hello to all I wanted to ask the following question.

I describe the system:

sliding door
on the door on the 4 sides are fixed wedges.
in correspondence of the closing, on the frame are fixed of the other wedges against which they go to press the wedges of the door that flows, so that the door shifts slightly, about 10 mm.

Now I would like to calculate the thrust force that I need to move the door and then shift it through the wedges.

I wonder, the force of raving friction that is generated between the wedges I must consider n times how many wedges are?

Thank you.

I certainly am.

 

[gtemp]

thanks for the answer,

Now I have a doubt.

the weight of the door is supported by guides and trolleys, so I wonder, what is the force that generates the friction reaction on the wedges? It can't be the translation force, I have to calculate it.

Thank you.

Well, a pattern?
Maybe make a drawing and calculate the reactions.
so on 2 feet I don't know!
