Complete rubbish. What you got to narrow down was how to steer off into the weeds when you were being led through how it worked. You are a master at deflection and diversion, that's all.

Prove that you understand Newton's 3'rd law.
Show how F2 can be different from F1 in diagram A or B, or how V2 can be larger than V1 in C.

Or show me a torque multiplier wrench that only has an input and an output with no requirement for the case to be reference/attached to something the third contact point.

In A, B and C there are only two points of contact and that is not sufficient to do any force multiplication. They all need a third point to work as force multipliers.

Or if you think B and C is correct but A is a diffrent thing show what the difference is.

(silly nickname, sorry).  I get the 2nd. example, right away, with that piston size difference between the left side and right side pistons.
The other two would / will take a bit, but I'm easily confused.

   My first problem was that your question itself didn't have enough detail, of what issue is.

What do you mean by getting the 2nd example right away ?
Do you understand that F2=F1 ?
If so that is great and the same applies to the other two examples even if they may be harder to get.

All 3 examples have only two points of contact an input F1 and output F2.
In order to do force multiplication so to have F2 larger than F1 you also need a third point of contact so the body of the vehicle at a) blue part will need to be connected to ground same as for b) the piston body will need to be connected to ground to work and for c) the blue wire needs to be connected to battery negative.

That's also a trick that anyone who has played with a yoyo for more than a few minutes knows how to do.

:) This is a discussion about physics. No device can do force multiplication if it has only two connection points as those in my examples.
3 points are needed to be able to do force multiplication.
If you think otherwise give me a link to a Torque multiplier that works with less than 3 contact points.
