How a differential works (retro film)
OK, so I was over at one of my other haunts and found this really cool old film.
Most of the seasoned guys here will just find it kinda fun while the folks that are relatively new to mechanics will find it informative. You may want to skip into the film to about 1:50 to avoid watching the motorcycles perform stunts and maneuvers. But, all in all I think it's a cool, laymans way of understanding how a differential works. Once you get the gist, factor in lockers. Either way you'll begin to understand the physics behind how your Jeep conquers terrain.

Its alright Dave, you just gotta know how to fix it. Not how it works. :flipoff:

I love things like this that show you just how ingenious different parts of our cars really are.

P.S. thanks for sharing, I've been having the hardest time trying to explain that to my GF (and it made me understand it better too:D)

Great vidoe. It shows in great detail how everything meshes together. But I really like how the importance of safety was observed even back then.

That does sorta make sense now lol, though i'm more of a hands on learner...

thats pretty cool. and the motorcycle bit at the begining is pretty neat to, u dont really see synchronized riding like that these days

Very cool...thanks for sharing!

Thats a great video...I bet if we remove the differential and put drums on both wheels like they had there at the end we could get our gas mileage up to maybe 15 or 16 MPG!
............Well, maybe not the circus performers would probably give out in a mile or two!

Best simple explanation----ALWAYS wondered how the contrapyion worked.
