Goooood Morning all!

I am going through a few problems in advanced dynamics with Hamilton's Principle.

One of them is shown above (this is NOT a question about the solution)

The spring constants, damping, mass, force, are all given. So, too, is the constraint: large disk rolls without slipping.

My question is this:

I suppose one could replace the "rolling without slipping" constraint with "rack and pinion" gear set.

My question is this:

**Does such a mechanical device exist?**I suppose one could replace the "rolling without slipping" constraint with "rack and pinion" gear set.

- But is this specific schematic representative of some real device?
- And, more generally, but just as important to me: as I go through such examples, how can I find out if the schematics for the varied problems exists?
- Or should I content myself with realizing that these are indeed simple schematics to learn the language of how to apply Hamilton's Principle? (much like found in electrical circuitry examples)
