Ever hear the phrase "Balls out" when referring to pushing something to the max? Comes form the balls of the centrifugal engine governor. At maximum speed the balls extended all the way outward giving us the term "Running balls out."
edit: I once said this phrase at a work meeting and someone objected to my use of a crude term which I then explained much to everyone's surprise. They thought it had something to do with testicles.
Definitely a fun note :). I think I heard it first from a Jay Leno youtube video where he was showing his amazing collection of steam powered machinery.
This is from the article, but governors also played a role in kicking off modern control theory!

In 1868, James Clerk Maxwell studied when these oscillations grow or die away in his paper “On Governors”[https://www.damtp.cam.ac.uk/user/gold/pdfs/teaching/old_lite...]. This became one of the beginnings of modern control theory.

Example, throttle controls on a Dogulas DC3. All engine controls forward is the typical convention for full power. (At sea level, neglecting the altitude effect on required engine fuel/air mixture.)
Fred Dibnah's BBC series "Age of Steam" is a fine overview of the development of steam engine technology and the industrial revolution in the United Kingdom.
Author here. The beam engine created power from steam, and was a key part of the early Industrial Revolution. The article is a deep dive into the engine: how it works, the history behind it, and the engineering tradeoffs the builders faced. There are quite a few interactive figures that I hope make the concepts easier to see.
This reminds me a lot of https://ciechanow.ski, down to the body typeface. (IBM Plex Sans?) Also, the SI units everywhere here make me beam. Thank you :)

- Thanks to Bartosz Ciechanowski, whose exceptionally well written and designed articles inspired this one.
Awesome! It's pretty amazing all the concepts that need to come together for even these very old engines. I found I built a better understanding of what was going on as I built out the animations as well.
Cool! If you're in New Zealand, there is a massive, two story Double Woolf beam engine at MOTAT museum in Auckland, along with an array of other steam driven engines that they run from time to time.
RE: units - Good catch - there is almost certainly a better way to phrase this one. I always tried to give physical examples to make things more concrete. But who knows, maybe the bathtub will take off as a unit :).

I suppose this is also the less colorful true origin of "balls to the wall" than the phrase itself suggests?
Nope. Balls to the wall refers to the balls on the end of throttle levers in aircraft cockpit.
Going balls to the wall means pushing the throttle and mixture all the way in for maximum power.
tbh, any time i've said it i've been referring to testicles, but thanks for the helpful excuse in future.
Similar to balls to the walls (or similar). Coming from the analog aviation controls I believe.
Example, throttle controls on a Dogulas DC3. All engine controls forward is the typical convention for full power. (At sea level, neglecting the altitude effect on required engine fuel/air mixture.)

That said, i'm sure the pilots were aware of the double entendre
Balls to the van der Waals

my grandpa had a table top model of a beam engine that he would power with a pressure cooker

Really cool site! Did you create the animations with videos of assemblies in a CAD package? Very noice!!!
Thanks! Yes, some of the animations were created from this onshape model, which I rigged for motion: https://cad.onshape.com/documents/ebc9190f428cf30153c06148/w....
For other animations I put together a style guide and worked together with Fable to build them.

Glad you enjoyed the units :).
For those in London who want to see one of these in the flesh, as it were, there's one in Tottenham: https://www.mbeam.org/
Great historical science book on the steam engine here: https://www.amazon.com/Most-Powerful-Idea-World-Invention/dp...
One of my favorites. Good read.
This is what finally made the idea behind Watt's condenser click for me.

First off, this is very cool, I love these kind of breakdowns from first principal.
This is sending me :)

Three units of measurement in one sentence, my favorite unit is bathtubs.
Thanks!

Those damn imperial measurements.
