The Secret Life Of Gas Springs

Sir, I will not be skipping past 17m 28s of anything you put out there.

"Be careful. Don't stupid." needs to be on some merch.

This old tony makes me feel like a kid again. 11 years old and home from school. It's raining so I can't go outside. Mom put PBS on the TV so I would stop bothering her about my being bored. The reading rainbow just started, and normally I'd scoff at the idea of an " educational adventure" but this time is different. I want that. Several hours later I can't stop talking at dinner about how much work goes into building a dam, or what airline pilots actually do. Having for the first time enjoyed learning something. This old tony thank you for making me want to learn again.

You made it the WHOLE WAY through the video without breaking the Wife's Glass Flour jar! I AM impressed! Good to hear from you, old friend. Thanks for the smile.

They didn't use a stretchy spring because it could be stretched past its comfy zone and will inevitably damage the spring. By using a squeezy spring in the configuration they did, it prevents damage to the spring and instead it hits a dead stop when it is fully squeezed... (But I know you know that Tony 😜 I commented because al gore has no rhythm)

The atmospheric pressure also pushes on the part of the piston outside of the cylinder. ❤❤❤

As a former high school physics teacher, I never stopped to think of the wonderful physics in a simple machine like this. Wish I would have thought of this as an example to use in teaching these concepts. Thanks for the awesome video!

Not realy relevant to the subject in the video, but I have to extend my deepest thanks to you Tony. Your videos made me interested in machining, and after a few years working as a CNC-grinder I realised that precision was my thing. Last week I graduated as a measurement technician (in the hometown of legendary C. E. Johansson) and this journey began with your videos. Again, thank you!

I miss the days when TOT was still new to me and I had like 200 new videos still left to go through 😢

Hypothesis re storm doors: when a compression spring bottoms out the load goes to something stronger. Tension springs stretch out and then snap (without even more complex extra stuff).

Sir, this is an absolute masterclass in explaining. That moment at 17:30, where you just hold the drill for just enough time to let everything sink in and let the viewer figure it out by themselves... Absolute gold.

I love the subtle nod to Tim Hunkin in that title and thumbnail!

And I was just about to go to bed...

Going through a pneumatics course right now so a lot of the info that was in this video is still fresh in my mind, and despite that the moment you put the differing extention and retraction forces on screen and was about to explain the constant force aspect of the spring it just clicked in my mind. Felt like a purely magical moment and I haven't felt that in a while! Also the reason the cylinder doesnt extend is because the 14.7 psi of air pressure is acting both on the inside and outside of the cylinder fully since its also able to act on the rod diameter so the forces cancel out. Wonderful video sir!

After you drilled the hole in the gas spring, you can see that there's nothing inside. So obviously you would know that the piston wont move. But when the gas spring is fully enclosed, there's no way to see inside; thus the intention of the device activates and pushes with constant* force. Good video! Learned a lot!

TOT - Thank you my friend, I learnt something today! I've been a motor mechanic for over 40 years now, I must have changed hundreds of those gas strut units in my time... I never once assumed there was anything that clever going on inside them and would have been someone to jump in and 'correct' you on the whole Constant Force thing. I dips me hat 🧑‍🔧

I was watching a film when I received the notification, I hit the pause to watch this video, because of priorities 😊

There is atmosphere pushing the rod in with the same force. Great explanation in general; learnt a lot. Thanks!

The two different screwdrivers are driving me crazy! 😂 ToT back at it again with the subtle jokes

Venting that bonus gas spring sure is one way to make it constant force! ;)
