You can use a mechanism like a bicycle pedal. Connect your bushing where normally the pedal is mounted. Either have it turned by the chain as in a bike or a servo. .

I question why you do not want the bushing to rotate relative to the thing passing through it because if there's no relative motion then there's no point for the bushing. You're going to need more detail. Because based on what you little wrote inserting the bushing into a off-center circular slot on a rotating disc would be acceptable. Sure the thing passing ...

I'll be combining the two other existing answers (so far). If you are interested more in ease of implementation and low cost then the way to go is connect each rod to a generator produce electricity and then use a motor to get the power at the rpm you want (Eric S solution). If you are interested in a solely mechanical system or if (at a lesser extent) ...

Use adjustable gearing combined with a pawl and spring coupling similar to a bicycle casette. When the target output spins faster than the input, the ratcheting mechanism lets the output freely (a bit of energy lost from the ratchet) turn. You'll have to figure out the adjustable gearing bit and how to increase/decrease the ratios based on what is going on. ...

You could have each rod drive a generator and then combine the electrical output of the two generators.

You are correct; "why not". Oil country pipe uses more than a hundred threads; most are proprietary. Each manufacturer will tell you why his thread is best. For highest strength in the axial direction, load flanks will be 90 degrees, or even negative. If interested in strange threads, look up Hydril- Tenaris Wedge threads

Finer threads are stronger. When you strip a thread you shear the threads themselves off the fastener. Say you need a thread that will ball through a 10mm hole with 2mm deep threads you have a 6mm diameter core they are attached to. 1mm threads leave 8mm. That's almost a 3rd more material. Added to that, for a given load it will stretch less so the load will ...

OnShape is a useful free (if ou make your designs public) 3D CAD program. There's an introductory tutorial showing some of the techniques to create sheet metal cylinder on YouTube TechProductDesign channel. Figure 1. The pipe with hole extruded from angled plane. Note the gap at the rear to allow the sheet metal flattening. Figure 2. The flattened sheet ...

If you are looking for an automated way what you would need to use is research homography (this is very close to the affine transformations which they also might be of help). This is too broad to cover here (and I am not sure that its directly relevant to what you are asking) so I will just provide some links and also what you can accomplish. What you can ...

Is this what you are asking? Below is a start.

But we know that projection plane is 2D plane where z-component is either zero or constant, so how is it possible projection plane intersects each coordinate axis? The projection plane is like the film / sensor of a camera. It can be in any orientation, not necessarily parallel to the (global) XY plane. So the projection plane can intersect all three axes ...
