Around The Corner - How Differential Steering Works (1937)
US Auto Industry
A 1937 GM-produced film explaining how the automobile differential lets wheels turn at different speeds around a corner. It uses clear animations and cutaway demonstrations to build the idea from first principles.
Held up as a marvel of pedagogy and the best explanation of differentials, recommended again and again.
