Add 2D-Cam - with a stationary Part
I have added a Rack Pinion to get the Linear Rotational Speed of a 'Pinion' Rolling up a Stationary Rack' - see the model attached.
This was only to get the linear speed vs rotational speed correct.
I want to add a Cam - either a cam in the frame and a rolling star of rollers
or a rolling cam with pins fixed in the frame.
In both cases the cam is not correct and no doubt to do with the relative velocities.
