I am sure you are pretty impressed with the engineering behind the gas nozzles. SolidWorks helped me a lot to understand the technology behind the gas nozzles. You may access an affordable version of 3DEXPERIENCE SOLIDWORKS for Makers here ( $38USD/year! | 20% Off) - solidworks.com/lesicsV3 You may download our SolidWorks gas nozzle file from here - www.dropbox.com/scl/fo/yo9hkkw4g7gt24zgmxl2s/AFvmAfxybP3fofiPFF641xA?rlkey=c2xzul7qhklo731733g0rrayx&st=dc03lxr4&dl=0 Cheers Sabin Mathew
Generally, this kind of mechanism is not invented at once. Instead, it does evolve in small increments, with engineers improving previous designs. Nevertheless, it is still a smart mechanism
9:16 "After three weeks of study, Solidworks and a lot of experimentation when I finally understood the complete mechanic of this genius invention I almost cried" Relatable
The work you put into making these videos is just amazing. I was thinking about recently while I was refueling my vehicle and here I have a video explaining it in such a great manner. Thank you.
Your explanations are absolutely amazing. I've heard this gas nozzle explained many times before but none of those were as clear and easy to follow as your video. Brilliant
As a mechanical engineer with some electronics /electrical feedback design, never thought of how purely mechanical feedback and differential pressures alone are used here just to keep it simple and abuse friendly. Very well explained using Solidworks and the animations. Wonderfully done
lesics is the best place to learn about electronics which is informative and easily understandable. I expect more videos about electrical and wireless communications
I knew the premise behind how it worked, a pressure change, but never really thought about how it worked. Quite ingenious. Complex and simple at the same time. Physics!
This was no less than brilliant. If you're looking for ideas regarding other complex topics that are worthy of the same detail, consider doing one on how a torque converter in a car works. Also, nobody has done one on how the automatic adjustment mechanism of drum brakes works through the star wheel. Both are mechanical engineering masterpieces.
In the UK, they don't use the automatic shutoff. You have to hold the hand-trigger down the entire time, no way to do your windows while the gas pumps.
May seem complex but it is the simplest design that we know of that satisfy all the criteria. That's why engineering is great, take a problem make a solution then simplify the solution.
Lesics please cover some electrical engineering topics- induction type Energy meter, power factor meter. These are something that even professors don't fully understand the workings
The shut-off valve was invented in Olean, New York, in 1939 by Richard C. Corson. At a loading dock at the Socony-Vacuum Oil Company, Corson observed a worker filling a barrel with gasoline and thought it inefficient.
0:00 as a matter of fact I have seen gas overflowing like that. the spring at 6:03 was broken or missing, which meant that the clip engaged on its own and was not unseated when the tank was full.
What happens when the user holds the trigger past the full point? In your design it would spill out, yet in Europe when I do that the system internally reverts to off even when the trigger mechanism is physically held down be it the clip or my hand. I am curious how that system works and why it was not implemented in the US.
I always like and follow Lesics and Indonesian Lesics, because the videos are educational and very detailed. but I have one question, the question is how do drone disabling weapons work?
I don't know what you're talking about. I've owned both a Nissan Frontier 2002 and now a Nissan Frontier 2019, and on both vehicles the gasoline overflows EVERY TIME. It doesn't matter which gas station I go to, it always dumps gasoline down the side of the vehicle before shutting off half a second later if I don't carefully monitor how much gasoline I have pumped and manually shut it off before the tank is full.
I don't understand why the green valve rod doesn't trigger the torsion spring and release the locking pawl when starting the flow of fuel. The green rod must be pressed upwards to open the valve, so shouldn't it be applying force to the torsion spring as soon as the valve opens?
0:10 ...0:15, But in Mexico if you ask an Automation Engineer or similar for that job, the first thing they will ask you for will be a PLC, their own PG and about 5 sensors.
Could this be adapted for very high pressure situations - ie hydraulic rams? It seems to me as if excavating vehicles might benefit from overpressure situations. But could the cone and ball bearing mechanism cope with pressures in the 50psi-5000psi range?
Love these videos. But I get confused as to what the channel used to be since I subscribed 2 channel names ago. It makes things harder to follow on RU-vid.
Hello sir, It's my request to you Please make a video about lightning arrester and aware the people about it's working and it's benefit also. As many of people lost their life due to lightning and due to lack of knowledge. I have also lost someone due to lightning and don't want anyone to lost one's own. Thanks❤❤
Using electronics in the vicinity of petrol is a danger. And these nozzles were developed long before electronics were made so cheap. I love how such simple mechanisms make our day-to-day life easier and safer.
9:20 "Lesics is struggling" - The employee watching video games in the backend 😂 Just kidding Great video thank you for all your hard work, it"s amazing.
7 months ago you did the 9/11 video and said the building 7 video would be out a week later… then you said it would be out by December… now it’s the middle of May and still no video.
But that doesn't explain why after shutting down you can press again and it takes a few seconds to shut again, I have seen 3L been added after the first shut...
Hi, can anyone help me please I'm a technical institute student at Hydraulic systems technology , how can I figure out the latest things in my field? And what are the big issues at this time in my field?
I have been watching your channel since 2018 and i must say you are best as i have learned and gained intuition about lot of things.. but i might say that either our indian engineering is not that great or you just dont like to praise the technological achievements or engineering marvels of our country..
I had one stop pumping but the numbers kept going to over charge me. I had stopped it at $20.00 it kept going until it reached double the amount, that's theft, screw you ESSO
