It depends on your tolerances. If they are tight enough so the gap is not too large, we can simplify and calculate the clamping force as follows.
First of all, since we assume the gap is small, we assume the force required to close the gap is negligible.
Clamping force Fi (provided by the bolt connection) creates a radial contact pressure p. As the ...

Your sketch shows that the door panels are hinged balanced at the center.
This means they are at equilibrium in any position and can turn freely back and forth. And unless you need to flap them really fast, no angular momentum concerns.
All you need to deal with is the friction at the joints and links. And that depends on whether your system is put together ...

Yes and no. It requires power to reach a speed ; gears do not add power. The proper gears permit to engine to get to the maximum power which will produce the maximum velocity for the engine power and vehicle. As a boy I had several differentials for my Olds (cheap at the junk yard) , ratios ranging from 3.42 to 4.30. It took less than an hour to change one. ...
