tangential bending

[Steppermotor]

Good afternoon to all.
Do you have any idea what forces to consider to calculate the force necessary to bend the sheet (white) and the effort that must bear the bearing in the fulcrum?
the presumed flag should bear the bending spout more the friction of crawling.
I tried to search the web but everything brings me back to the molded bending in air or coniatura.
I tried to make a similarity with the funnel but in this case the flag follows the curvature, instead the contact is tangential to the connection of the mold, probably it is the same thing but perhaps also not.
thanks to everyone in advance.

your sheet protruding is nothing more than a beam framed between a primer and a lower bench that protrudes to which the force f.
therefore you have to calculate the bending voltage at the base, using the formula animal.as you have to make a permanent bending you have to use the plastic bending moment and not the elastic one.Once you have done this, as you fold it with an additional lever, you have to calculate the balance of arms and then you calculate how much manpower it takes to generate the plasticization force applied on the iron plate.
Keep in mind that then there will be an elastic return.
the friction of the pin is almost negligible in first approximation.
I would say that this is a starting point.
then there would be to evaluate the movement of the fiber neutra compared to the radius/thickness you bend, but here we go on the end. you can refine....if you put everything in excel you implement first easy and then more complete.

Thank you very much for the answer.
I attached the excel file but I assume I made some mistakes.
I hypothesized the contact on the farthest point of the flag thickness.
I do not need to go very much in detail and work until but simply understand the forces to manage and if it can be an application that needs air cylinders or hydraulic cylinders or use of mechanical jacks, provided that everything depends on thickness and length of the sheet.

the terms length and width, without an indication to a scheme are practically "personal". You don't understand much at what distance you refer to.
also for the application of force on the lever you have to do: a teygonometric sudium if you use a cylinder otherwise the force you apply is perpendicular to the lever and then solve it as a sum of the moments around the point of rotation.
Did you use the plastic moment?

I bring you the formulas to have a first approximation an indicative value of the force to be applied.with wf elastic flexional module. wp is the plastic one. as I told you you not only have to get to do an elastic bending but it has to stay in place so the section has to plasticize. f and p are agreed because they are two actions and not an action and a reaction... otherwise in balance we should have f•l = - p•h

try to see but your numbers aren't coming for lerrdour in your last formula and not considering plasticization.

Good morning, everyone, and I'm sorry I'm late, but I was away for work.
Thanks mechanicalmg. in fact I have relived and calculations and in fact condensation in a few lines on excel made me commit a catastrophic error.
I have remade the sheet with your values as verification and obviously everything comes back.
