LML001 is a simple transformer from one translation motion to another. The conversion formulas
do even not use the angle, but simply the ratio L1/L2.
The limitation in angle simply ensures that the evaluation of the angle corresponds to something physical.
To clarify the way it works, I would have used the representation below, using racks connected to
2 pinions of radius L1 and L2. Then no problem of angle.
If the angular position has an importance in your model, then you should switch to 2D world by
using Planar Mechanical library.
