> And as a bonus, an explanation about transistors from 1953 And here is a 1959 video from the same source about wave behavior [1]. It covers reflection from open and closed ends, superposition, standing waves and resonance, impedance mismatching, and tapered-section transformers all in a way that makes it really easy to understand.

> Also: this is not how modern power steering systems work. Yes, most hydraulic systems today have been replaced by electric power steering, which uses electronic sensors to determine how much assist to apply via an electric motor. Mechanically, it is simple and very low maintenance.

>Yes, most hydraulic systems today have been replaced by electric power steering, which uses electronic sensors to determine how much assist to apply via an electric motor. one small nit to pick many modern electric power steering systems are still hydraulic by nature. It's sometimes the case that the electric motor is driving fluid to enact the resistance change. Many cars that use Bosch electronics/driving-aids sti…

rack and pinion has been the standard for nearly all smaller passenger vehicles since at least the early 90s. you can find things like that or like pitman arms on larger/industrial vehicles fairly commonly, though. to your point, however, yes -- sports cars were the first ones to popularize the method. Rack and pinions tend to feel less 'sloppy' , especially after some use. The idea stuck around in the industry thoug…

So was recirculating ball a halfway point between worm and sector and rack and pinion then? We have a 1947 Willys CJ-2A, which I believe is worm and sector, though we haven't gotten into the steering yet because there are so many other things wrong with it. Including, it seems, the formerly working brakes. I discovered they had crapped out as I was backing up near a bunch of formerly neatly stacked cinder blocks.

Why does that title here and on YouTube say 1956 when the video itself says 1955?

I thought recirculating ball[0] was commonly used in most passenger vehicles, and rack and pinion was more common in sports cars. [0] https://en.m.wikipedia.org/wiki/Recirculating_ball

The only recent example I'm aware of is the Ineos Grenadier, and it's quite controversial as it means the steering is a) slow, and b) has very low self-centering (also a function of caster).
