Thank you for making these resources freely available for anyone and everyone who has an interest in learning about these subjects, Mr. Pytel. I am interested in learning about science and how it applies to our everyday lives, but find it difficult to wrap my mind around such complex processes. That is one reason I never paid more attention to it in school (along with the fact I preferred to daydream and do most anything else than schoolwork). Now I operate carding machines in a nonwovens plant and am desperate to learn new skills so that I can get out of my self-induced misery as a general laborer. I'm 28 and feel like I'm wasting my life, but better to learn later rather than never. I appreciate the fact that you make it easy to understand (even as horrifyingly complex as it is) and also your sense of humor!
I’m an engineering student at a state university, and let me tell you, lectures are normally extremely dry. It’s frustrating to me because I find this stuff to be very fascinating and it seems like my professors hate teaching. Being honest, I don’t come to your channel for help with topics; I come here because you’re hilarious and you’re passionate about what you’re teaching. It’s nice to see some life in an area that is often consumed by a lackluster teaching style. Aside from that, you’re teaching concepts that people will frequently use in their career; this is fantastic. Best part of this video: “I suppose you could make them square or triangular... but that would be stupid and no one does it.” Don’t change anything about your style. I might have to take a class of yours some day.
Feel free to do so. Here's the associated study guides for the entire hydraulics series: openoregon.pressbooks.pub/hydraulics/ Working on a pneumatics series as we speak.
This is very simple stuff! I would never have known this without your most generous donation of time and talent. THANK YOU VERY MUCH! I will now fix my backhoe.
WOw,i normally dont comment on youtube videos, but I just want to say thank you for such a great lecture, the way in which you simplify and easily explain everything is really amazing. I have learned and gained so much in one simple video clip. Thank you once again. Great work
Ok so either you are Josh Lucas (home Depot commercials) incognito... Or you sound freakishly identical to his voice. My verdict: the famous actor Josh Lucas secretly makes hydraulic videos on RUclips. 😎💯👍😂
Thank you so much for creating these videos. They are very clear and understandable. I am currently in a building and utility mechanic program at a tech program. I would like to get in touch with you about the use of these videos in the curriculum.
Levi Price Thanks much. My short answer is, "Yes. Absolutely. I encourage it." Message me at my gmail account and we'll chat about it. I've had some experience with teaching technical subjects using online resources. Long story short, a flipped classroom approach allows more hands on time with equipment. Learning can happen anywhere at anytime. My intention is to eventually create a resource for this type of learning that anyone can use.
Mr. Pytel, I have watched your most informative lectures on pumps.My question is this: since pumps move fluid and create the flow through the system, what is actually creating the desired pressure? Is it the clearances between the "squish" areas in the pump or some restriction or orifice in the system that gives you 500 PSI or 1000 PSI etc? Or spring tension in a regulator?
+D. G. Pressure is the result of restriction. The classic example is a transfer pump (ie: pumping water out of a pond into another pond). The output of the pump is at low pressure since there isn't really any restriction. If, however, the pump is pumping water out of a pond into a rubber balloon, the expanding balloon exerts a resistance and therefore pressure rises. Similarly, if a pump is pumping water out of a pond into a rigid storage tank, once full and all air evacuated, the rigid storage tank exerts much more resistance and therefore pressure substantially rises. Hopefully, this helps.
So a built in restrictor/restriction is designed into the system.The next question is there a simple way of calculating the size of the restriction for a given pressure that you want? Tx for your help!
+D. G. Not exactly. The system and applied load IS the restriction, check out the Pascal's Law lecture at: ruclips.net/video/YNoPs9kH7Ao/видео.html hopefully this will explain it.
To D.G., What I tell my students is that the pump creates the flow and the load creates the pressure. If a pump works against a very light load, the pressure will not rise to a high level. If the load gets to be great, the pressure will rise to push against it. The pump will feel the load through the cylinder or hydraulic motor that it is connected to. That's a short explanation. Good luck.
Jim, to explain the hydraulic cylinder with clevis you take as a example a wind turbine generator. So, is it possible that there is a stop tube in the cylinder in this case? I read a bit about the stop tube advantages and it prevents a excessive extension of the rod and reduces side loads in the rod. I think in wind turbine generator there may be a excessive extension and due to the angular movement of the cylinder a torque is created and consequently a radial stress. Nice leacture!
A properly engineered mounting system would ideally limit side loading and eliminate the need for a stop tube. Eventually I plan on publishing lectures detailing industrial wind power that show a hydraulic pitch system in action, however, imagine a body trunion (ie: trunion arms on the barrel) pivoting cylinder mount. During extension, as the head (rod) tips one direction, the body (cap) tips the other and the cylinder's travel remains linear.

Just got hired as a Hydraulics Test Engineer Intern working on actuators for landing gears. These videos are extremely helpful thank you!!

Excellent teaching and presentation. As a hydraulics distributor for over 20 years, I can say that this is TOP NOTCH! Would love to share this video.

@@bigbadtech Thank you very much! Excited about the pneumatics series!

This guy is born to be a teacher! Great work!
Great work. Optimum speed, no useless info or nonsense.
Love your sessions mate. Its so helpful and the way you have explained it and the flow of the presentations....love your work
Your video's are fabulous. We're using them at work to supplement the formal courses at the local learning institutions.
WOw,i normally dont comment on youtube videos, but I just want to say thank you for such a great lecture, the way in which you simplify and easily explain everything is really amazing. I have learned and gained so much in one simple video clip. Thank you once again. Great work
I was in the Navy Seabees and played that push ball game with some Army gents when I was in Kosovo. It was a blast from what I remember
I still have a knot on my shin from that game.
""you could make cylinder a triangle in shape but that'd be stupid" lmao
This is thorough. Thank you for this lecture.
Glad you're making use of this material. Please let your friends know these resources exist!

Very good lesson man, thank you
can you do a video on selecting a cylinder from a manufacturers catalog ?
ThanKs for a huge clarity video ❤❤❤
But wait there's more! Check out the complete hydraulics playlist at: ruclips.net/p/PLdnqjKaksr8ruhw85YYSSO6EWLhVVmSKm
Excellent Work, thank you so much!!
MR PYTEL don't u have any course on wind energy ? and thank u alot
Stay in touch. Industrial wind power lectures in the works.
excellent!
Good show.
Great job
Thank you!

awesome lecture.
Treasure for everyone to pick up :D
Incredible
thanks alot
give up collage & watch jim pytel's videos
