One of the
Atkinson Differential Engine
prototypes "running"...
One of the most perplexing engineering problems that
had to be solved was getting the crankshaft to revolve one way while the
flywheel revolved the other. It wasn't until a special velocity reversing
joint was developed, that the engine would run properly.
(Actually it's called aliasing... a result of animation... just like the old western movies with the stagecoach racing down the road with its wheels slowly revolving backwards... I came out of childhood very confused by that...)
