Determining what it takes to bear the forces on a steering wheel …
↓↓↓ Complete description, time index and links below ↓↓↓

In the last video we measured the forces I can exert on a steering wheel (link below). I do have an idea of how to build the whole thing: An aluminum shaft with a wheel attached running in a POM bearing. But how beefy has everything to be?

First we make some static calculations for the radial forces acting on the shaft and the bearing. Next we treat our shaft as a beam under bending forces. Finally we cover the edge load of our POM bearing. And that’s just for starters.

00:00 Intro – what does it take to bear a steering wheel
00:38 Construction – aluminum shaft in a POM bearing
01:59 Radial forces – acting on the shaft and bearing
16:44 Shaft bending – inside the bearing
26:41 Edge loading – pressure at the front of the bearing
35:41 Wrap-up – enough for today, more calculations ahead, bye
