For your viewing pleasure, this 1930s instructional video released by Chevrolet tells us all about how suspensions operate in remarkably simple, yet entertaining, terms.

The film, dug up by the folks at Road & Track, was intended to be shown to mechanics at Chevrolet dealerships. It appears to have been developed by the automaker's training department to educate either sales people or consumers, although its detail and length mean it may have been meant for internal audiences.

The Spring Harmony film was no doubt released alongside many others promoting Chevrolet's advancements every year, but what makes it so interesting is that it has been preserved. No doubt many of the General Motors Company [NYSE:GM] division's promotional films have been lost over the years.

Staring off in heady 1930s style, which often takes a macro look at the world, the video informs viewers that Chevrolet cars were designed to make passengers comfortable on any kind of terrain. The film is worth watching alone for its graphics and its vintage footage, although we suspect you'll learn a thing or two about how remarkably advanced cars were in the 1930s, only a couple of decades after they became mainstream.

Stay tuned to the entire video because there are some great scenes of the 1930s Chevrolet in action scattered throughout. We also have some similar footage outlining the inner workings of a differential and a manual transmission.
