Here is a Man that not only knows what he's talking about, is enthusiastic about it. You know when someone loves what he's talking about! Cheers from Portugal!
I'm not a native English speaker, even though I learned so much with this lesson! Your passion is something that every single person who watched this video may feel! It's amazing and extremely beautiful how much love you've put on it! Thanks Andrew!
There is one hugely appealing characteristic that Andrew Szydlo shares with other great science communicators like Professor Sir Martyn Poliakoff and David Attenborough (to name two of my favourites but there are plenty of others) and that is enthusiasm. None of them is a young man but they have never lost their love of knowledge and learning and that shines through whenever they talk about something they are interested in. I love it.
27:45 - Never do that without safety goggles, a small slice nearly always flies off at supersonic speed (you can hear it hitting something behind the camera), same as when you break spaghetti.
Ah.. video from the Covid 19 days. I saw this one a couple of years ago. I just had to watch it again. I just like the way Andrew Szydyo talks and demonstrates things. Thank you. From Virginia, United States.😀
Thank you so much! I teach my children physics and just last week I bought my 9th grade son a mechanical pocket watch (he asked for it). I want him to understand how it works.
I was in the US Marine Corps from 1975 to 1995. I began may career as a teletype and crypto technician. I throughly enjoyed this presentation. The teletype uses a vast number of springs to accomplish it’s task. While a motor is present, it mostly loads the springs which do the work. Also, teletypes are great examples of receiving a serial electrical signal and converting it to a parallel mechanical action, and the reverse in transmit. Great program!
Alexander, Metals in the service of man. A great introduction to the world of metallurgy. Think it was a war time accelerated education for a workforce heading into armaments, airplane and ship building.
My first introduction to a wound spring, and practically all of clockword for that matter, was removing the wrong screws in a dysfunctional kitchen timer about a month ago. One that was never meant to be maintenanced, I might add. This of course, resulted in every gear being strewn across the room by the mangling of main spring. Only the tuned mass remained in place, being fixed as it was on one end of the 'hairspring'(just learned that word from you). That took quite the concentration and learning session to get back together.
Even though there was no maths or complex analysis i feel I've learned more about springs from this good man in 37 minutes than i did from all my mechanics and design lecturers in my years at university, no shade at the staff of my university's mechanical engineering department intended, just stating facts 💯💯💯💯💯
@Kevin Original I'd actually say chime on cause you're preaching right now. I agree that degrees are being debased. As for these 'authors'... I can tell you in my years at university there was only 3, and only 3, prescribed books that I could deem worth its price. I had a Russian Prof for my final year lecturing me, hella smart guy, does AI stuff when he's not lecturing, he told us "use textbook for examples only" and followed with "for the course follow me and my notes, ignore textbook. Authors just want to show how smart they are, they can write utter nonsense and be published, no care for understanding of information" and he was right, I wasn't great but I indeed passed the course on the first try despite it being the hardest course of the level
EVERYTHING is a spring! Instead of springs and geared drivetrains, the kids now can use a LiPo, ESC, transmitter, and receiver and can accomplish what is effective the same thing. Kids of today are no less smart for not having the same toys as the kids of yesterday; it's simply a different skillset. What a wonderful video by Andrew, thank you!
You are a lover of art, sir. Art is in its basis skill that exceeds the mundane, done with emotion that is communicated from soul to soul through the work. His passion for science and teaching is certainly like a powerful wave crashing on you.
FR lockdown has unlocked so many hidden treasures we keep at home. Absolutely fascinating and so many applications in robotics and just energy storage in general.
I have totally no interest in springs, but this man has such esteem and vigor(well these words came to my mind because of his oldschool style obviously) that I am watching this to the end.
I got all excited when I found a fusee movement online that was a "JOhn Harrison". Turns out it was a different JH. But still cool as it seems to have been made in Liverpool in the 1840's! Great VideO
Very surprising and incomprehensible that Mr Szydlo does not mention Hooke, Hookes law (Ut tensio sic vis) or the fact that he made the first balance spring watches. Experts!
@Andrew Did you configure your camera to record from your lapel microphone instead of it's on board mic? I ask because your voice sounds very far away and indistinct, even though you're wearing a lapel mic, and yet when you get close to the camera to show us a gear, your voice gets very clear. That makes me think we're only hearing camera audio, not the lapel.
Loved this! I would like to see spring technology in all 3 it's existing functions, and perhaps some pioneering ones, applied to the engineering problem of surviving interplanetary probes on exoplanets which are too hostile environmentally for modern electronics to survive.
The talk was interesting, but I was too busy gazing longingly at the Progress Junior 12S pillar drill, and Myford Super 7 lathe in the background. The Myford's a pretty nice piece of kit, But the Progress is a really nicely made and almost infinitely rebuildable tool that (With proper care and maintenance) your grand kids could one day be passing on to THEIR grand kids. In this current "Buy cheap, replace often" culture we live in, the engineer in me still likes to see tools about that were designed to last AT LEAST a lifetime.
Yes Andrew. Love the work a secret engineer really. I loved the video even though I repair garrod movers n clocks n anything wind up or weight driven n the 4 dislikes are from non engineer's
We did all that making chisels in metal work in Watford Grammar School for Bogs, beautiful colours went on later to see tempered colours on Trident Exhaust.
Love him! The kind of person who sees a screw that secures something and immediately pulls out the screwdriver! P.S. Is there a way to use a broken main spring to create some hydrogen gas? We absolutely need to fill a few balloons!
Another utility of springs I didn't hear about in the video: with them you can make scales (dynamometers, actually) and know the weight of objects (or the intensity of forces in general). Many years ago I bought two dynamometers, just for the fun of it. One with a capacity of 30 g and divisions of 1 g, and the other with a capacity of 10 g and divisions of 0.2 g. Surprisingly enough, I never used them (or any other contraption) to sell drugs.
I am sure that many of my vintage introductions were toys like cars. We soon learned to make them go we have to wind them up. If my memory serves me right, wind up toys came before inertia motors.
In case anyone is wondering about how to do the opposite (i.e., turn a piece of non-springy steel back into a spring), it's a two-step process. First you heat it to a high temperature (around 800ºC), then quench it (making it hard but brittle), then you heat it again, very slowly, to a controlled temperature (typically 293 ºC, where it stops being brittle but doesn't become malleable).
I have disassembled first alarm clock when I was 5 years old, I think. It gave me the general understanding of how it works. And lots of gears and springs. It is really odd to hear that there are people who do not know what spring is and how it works. I guess I am looking from not very common perspective, of someone who had lots of mechanical toys back in the day and was always curious what's inside. Nowdays the kid would hardly understand how tablet computer works if they break it open.
Just over half an hour of discussion & demonstration of various sorts of springs, & not one mention or Robert Hooke & his eponymous Law? I'm somewhat surprised!
@@dragonslayerornstein387 I wasn't asking how often you have to wind it. A watt hour (Wh) is a unit of energy. Batteries will be labeled in watt hours or amp hours. Knowing how much energy the spring stores, and that it lasts (say) a week, we can then determine the power demand of the pocket watch in milliwatts. It would be interesting to compare that against an electric device.
@@JohnDlugosz A pocket watch needs and stores very little energy. I dont know the numbers, but it could store as much as 2-3 minutes of energy for watching this video. Maybe less... Probably much less. It would be easier to compare to an RC car since I have seen both. A battery operated RC car 30 years ago, using old batteries would run for 10-15 minutes. A spring loaded car would run for 5-10 seconds if it was really good, a normal would run for 3-4 seconds. So a pocket watch working for a week is not about large energy storage, but minimal energy use.
Sorry I can't give a proper answer, but as a starter, if it could store 1 watt hour (3600 joules) it could spin a 100% efficient dynamo to produce 6 volts at 1 amp for one sixth of an hour, ie 10 minutes. I reckon it's about two orders orders of magnitude less. So maybe 10 mW hours or less. The watch mechanism must be in the microwatt region.
Man, i cant believe my generation. *pulls out pocket watch from the 1800's* whats it run off of? "batteries".... "no one had a clue what a spring was" like seriously wtf
My generation had mechanical toys and was always curious what's inside. I guess, if modern kid breaks his tablet open, he would hardly get any knowledge out of it. Except that the tablet was expensive and now it is broken.
Am I the only one that can't believe this? I thought nearly everyone above the age of five knew what a spring was. I can't even remember learning what a spring was, and I remember learning about simple machines like levers and wedges as a little kid.
Ah but no mention of bending vs torsion, or less commonly pure tension and compression. Still, not a bad video. A less common spring is found on late 1960s and early 1970s Dodge cars, they use the A-frame design but no coil spring, instead they have long straight bars in torsion. Parallel to the chassis frame, one end connected to the chassis and the other into the A-frame pivot. The connection to the chasis was rotatable (in a garage) to adjust the amount of tension and thus the stance of the car for both driver handling preference and minor changes in weight with the different engine options.
This was great but may I just correct something? Those are not grub screws. Grub screws don't have a head (they are the same width all the way along) whereas those screws clearly do.
There is an old joke in Germany, at the cost of young people. 2 minors meet to to show each other what they have got for Christmas presents. One of them shows off a latest tech electronic device. The other says ´My grandfather gave me a miraculous wrist watch.´ His friend inspects it and says ´It looks old and used `. The first says ´It is used, but now watch the miracle : All you have to do is to give a few turns to this little cogwheel, and it will run. It will never need a new battery !
alephii yes sadly, today in US schools it’s usually only the students who introduce Glocks to the class. Now I’m just hoping that my joke‘s not going to recoil at me some day!
I find it a little disappointing that so few younger people know how these fairly simple mechanical systems work these days. Sure, you wouldnt expect them to know how a watch works and stays accurate, but knowing a wind up watch uses a spring seems like it should be common knowledge.
Never oil an old clock or pocket watch, oil attracts dust which wears out the gearing. The gearing faces after years of working become hardened, wear that off it's goodbye beautiful watch or clock.
