Algodoo

This started by tracing images and drawings, I end up just place things close to what I see. I couldn't understand most technical documents I found, nor did I understand the overall effects of the joint's placement, but this version turns out to be working well enough.

----------

- Things are placed where they seem to fit, snapped to the grid.

- Without the swinging-sliding mechanism, it works better with extreme motions.

- You could edit the engine's power by changing the postStep value of the power displaying rectangle, using the Script Menu.

- For this scene, while the engine is running, moving the reverser to the opposite of the running direction could act as advancing the power timing, causing the wheel to turn even faster.

Feel free to edit.
