A Vintage GM Training Film

Here's a pre-war General Motors training film called Around The Corner. It just goes to show you what creative film making was like in the days before CGI. Can you imagine anyone doing some of these motorcycle stunts today? Er, I guess the helmets would get in the way today.

At about 2 minutes in, the film makers finally get to the point - how an automotive differential works. Once you see the ingenious ways they demonstrate differential technology, you will be amazed.

And you will never forget why you need a differential and how it works. The film makers actually manage to make the subject interesting while imparting dry engineering info. The scene of those people running on the rollers attached to a car's drive wheels at the end is bizarre.



This post at kottke.org got me going on this thread.
