The crushing force will be equal to P=F/A F=mg while the load increase will be equal to:F+T0.This is what I thought.

For the position shown in the plan and with the data indicated, determine the stresses in the three elements. Develop a first approximation construction solution of the equipment, to be made in a few exam. I thought I would first find the external reactions at the base of the column (fixture)...

so I separated the two bodies with force

the friction force is directed along the fabric

the solution made by me is wrong, so what is the exact solution because I am not understanding how to set it up. Thank you all.

This is my solution.

ok I understand but, could the solution I posted be ok?

on the crushing load, I thought that since the force acting on the mass is known, multiplying by the contact area A=200 400 I obtain the crushing pressure.

how is the reasoning valid and is the solution correct?

this is my solution but, the dimensions 200 and 400 mm are the length and width of the moving plate?

Unfortunately, that's the way the design is: it's a task that requires the construction of machines and as such, one has to make assumptions to solve it.

I'm sorry, now I'll make a post in the student area

The figure shows a device for ironing, or other finishing operations, a roll of fabric. The fabric is fed by the braked drum A, guided in the horizontal section by the idle rollers C and D and collected by the motorized drum B. In the horizontal section, the fabric is pressed by the movable...

Ok thank you so much.
