How Open Differential works Tiny: Er. I still cant see how both back axles turned independently, watched a few times but you got me. Both axles are in contact with the spider wheels so are effectively locked together, so how can they turn independently? Certainly a clever peice of engineering.
Is there an dummies video guide to this video?
Great graphic by the way. Even though I'm stumped.

Not all rear end have a back cover. A Ford 9 inch has the cover as the center of the rear end. To remove it you pull the axle covers off, pull the axles out and take the center out of the pumpkin.
Also if you have the trans in park or in gear and you turn one wheel the other one spins in the opposite direction.

Enjoyed the video. In your example, are the changes in speed really inversely proportional. For instance, if you slowed one wheel down to 1 RPM from 300, it wouldn't make the other wheel go 90, 000 RPM. It seems more like an additive/subtractive relationship, where the lost RPM of one wheel is found on the other.

The only change to this video is the pistons and their connecting rods are mounted to the CRANKSHAFT not the camshaft. The camshaft is turned by the CRANKSHAFT and the camshaft is used to move the valvetrain which opens the intake and exhaust valves.

Whoa, big boo-boo here! The pistons do not rotate the camshaft, they rotate the crankshaft. The camshaft does not transfer power to the clutch. You need to get your terminology right if you're going to be explaining how things work.

The only thing that i would personally add is a presentation on what happens when one wheel looses grip. But i guess this may pop up on a more advanced diff with a locking mechanism; )

I remember reading many years ago that straight cut gears were more efficient but were much noisier than spiral cut gears, so car manufacturers chose the quieter option.

Hi Paul.
Would it be possible to make a video on how Gas System/Combi boilers work?
Ive not seen a good explanation yet and would really appreciate it

reply

The video does not explain why open differentials are - or can be - inferior in snow or on wet grass.

I don't even have to watch the video before the upvote, I just get that out of the way while the ads play
