This may be the most empowering video on CZcams. It's literally life changing for me.
If you liked this, I highly recommend reading "Kinematics and Dynamics of Machinery" by Norton, it shows graphical examples and solutions to 4 bar mechanisms with specified motions.
This is the most informative video i've seen on four bar linkages, it's completely demystified it for me.
Very nice video. You can also do a simpler approach: make a circle using the 3-point circle method through all three points A. Do the same with points B. The center of the circles is the chassis pivot.
This video is amazing! I have always wondered how people design different hinges for cabinets and stuff. Now I can create my own for a 3D-printing project I am working on!
Thanks a lot! 👍
What?! I’ve always been curious about the complexities of engineering similar mechanisms... I had no idea it could be this simple. Very succinct explanation and example. This video coupled with the 3D printer I got for Christmas, whew, I’ve got some stuff to make! Thanks!
What is lacking with Mechanical Engineers today, is the knowledge of how to design mechanisms correctly. Did know that there's a mathematical formula that can be used for all mechanism designs? It's called Gruebler's Count. I found a way to make it practical for all 3D mechanisms. Here's the link if you are interested. czcams.com/video/KFB8gMjxDPk/video.html
not simple
This deserves a lot more views
Definitely
I appreciate your contribution to the understanding of the mechanisms.
I have been looking at how to do this for like over an hour, This is sick! Thank you
This video got me from being clueless about this mechanisms to printing my own in half an hour. Amazing video!!!!
I've been needing this! Thanks for the great explanation. I never knew it could be so simple
This is truly amazing, I've been using these tools for years and never even thought to trace a path like that. Incredible !
Holy Macaroni, that's a great video. 24 year Solidworks user. I learned a bunch today.
Thank you so much for the tutorial. Clear and precise.
You just made so many projects way more easier than I ever thought possible! 👍
Fantastic! I've been looking to understand exactly this concept! Thank you!
Thanks for the valuable and generous sharing.
Blows my mind. I always wonder how engineers did that on the vehicles. That’s super cool!
Outstanding video! Incredibly helpful, thank you!
you sir are my hero, this was a brilliant way to explain this.
This video was the best. Helped me a lot, Thank you.
I don't even... how do... wha.. When you see it come together... I'm 40 and today I leveled up thanks to your video. 20+ years of drawing and milling experience never had a clue as in to how to begin to tackle this things... and the timing! I HAVE to do one of this things for a project I'm working on... I mean, dude, Thanks A LOT!
Glad to be a help!
That was way too practical. Amazing work thanks for sharing
Thank you so much! This is a great video, one of thee most important I've ever seen.
I'm an electrical engineer by trade, but I like to dabble with mechanical stuff. I like to build stuff in Solidworks and make 3D prints from them.
This is Liquid GOLD
Great video. It made me understand the mechanism. Thanks!!!
Awesome work! This video is super hrlpful!
Awesome video!! simplified to it's essence :)
Great video, so many uses, liked & subscribed 🔥
awesome dude ! thanks !
Awesome. Thanks for sharing
THanks, this helped a lot. Learnt a few things.
stellar work!
Thank you! You helped me a lot!
Great video and very easy to understand.
The information super highway contains super information! Thankyou for this video.
Thank you. It really helped me to understand the mechanism.

Great explanation. Thank you
This video was amazing!
Best video I've seen on the subject
Great video. Interesting to learn.
We need more videos like this.
Man! You deserve to be subscribed to...thank you
Thanks for the great explanation...
Thanks for the video. It helped me tremendously. I just wanted to add my alternative to your method. Instead of drawing lines between the points, then bisecting them with perpendicular lines, you can just draw at 3-point circle using A1, A2, A3 as the points. The center of the circle is the exact same place your intersecting lines meet. Do the same for the B points and bam, done.
or draw just two positions of the hood and then a circle A1 to A2 and locate the center of the circle as you want. I learned a lot today!
Wow, you're right. I tried both ways and found your circle method to be much faster. Thanks for sharing!
@@vitof.4626 That's really fun to play with! I like that by just defining a start and end with the two circles connecting them, you can play more freely with the motion and easily try many cool motion paths. Thanks for the suggestion!
The information super highway contains super information! Thankyou for making things easy.
Wish you would do another one, fully defined with an actual real application, again loved the video!!!!
Wow great video!
Good demonstration of real case
Beautiful

4 bar mechanisms are really cool. Nice vid 👍👍

Thanks!! This video was perfect. Clear, easy to follow, practical, concise, could not ask for more.
Brilliant!
awesome video!
LOVED IT.
PLS BOSS, YOU GOTTA TELL ME WHERE YOU FOUND THIS METHOD.
AND YOU GOTTA UPLOAD MORE DESIGN METHODS FOR OTHER MECHANISMS
This is awesome thank you!
What great music and amazing instruction!!
czcams.com/video/vFDMaHQ4kW8/video.html 💐
Brilliant
Wow! Amazing! Thanks for sharing. I have a question, is it possible to construct more elaborate spatial mechanisms using 3D sketches with this technique?
Bro you are a genius 💪🏾
Have a like my good dude, excellent!
Super helpful!
Thanks Sir❤️❤️ , Easy to understand ,
Would you made some more tutorial on this topic ..
Very good information and easy to understand. I use Cro but the cad explanation was simple to understand irrespective whichever software we are using. Nice work.
czcams.com/video/vFDMaHQ4kW8/video.html 💐
It was amazing knowledge to share, can you recommend some book to create such mechanism in a graphical way in the initial conceptual design.
Awesome
Thank you so much for your cool video
Could you also please make tutorial videos about the other mechanisms ?
Incredibly helpful and easy to follow, but one question. How do I analyze the degrees of freedom in this?
Hey bro, i really didn't think it was that easy, one thing I think might be super useful is to use Sketch Image and take three pictures of you car with the tripod and make the accurate mechanism used in the car and the trunk
thank you !
Recently realized mechanism design might be one of the most important subjects in mechanical engineering. Thanks alot for the presentation. Wish to know if there are some books you might recommend for this
Design of machinery
really nice
Very helpful video😊
Thank you sir 👍❤️
Super cool 😎
Great instruction, thaks. Do you play the music while making the video or is it added later to distract us?
Hello: Could you demonstrate when you have a limited space, as in the trunk example, when you have convergence points way out there as your example shows. Thank you.
I've been trying to get my head around a crank -rocker mechanism with the desired range of motion. I thought I understood it when I got my first solution but apparently, not.
That's pretty good. Thanks a lot
czcams.com/video/vFDMaHQ4kW8/video.html 💐
what about when your convergence points land on the wrong side of the part?the trunk clearly went over center, so at that point do you just have to redraw along its path somewhere?
Hey, thanks for ur video. In the video without dimensions you defined a 4 bar mechanism that mimics the movement you want. But in order to get real model how you defined dimensions and preserve the exact movement ?
excellent
In this style of video can you just keep expanding this knowledge, levers, linkages, ect
Awesome video. I wished I had solid works. Question, working on a project although hinge needs to be on the outside. Was wanting to design a hinge to be pulled by a lever or actuator to open the grill lid. Any ideas designing from the outside?
Thanks! As far as your hinge setup goes, the pulling actuator should work as long as the force and travel needs are met and the actuator doesn't run into anything. Also, you could look into a pushing setup if you move pivot joints outside of the pit sides (if I'm picturing it right).
Been looking for this video for a year lol
First of all thanks for the video Man!
Thanks for the great explanation and simplication of construct the required mechanism.
I loved the procedure the way you have explained.
Thanks a lot for giving a clear view to crack those type of mechanisms.
Could you please tell me on which platform that I can do those things? Plz this will really help me to crack a my own mechanism.
Thanks! I use Solidworks but any 2d cad that allows lines to be connected like I did in the video should work just as well.
@@DirtyElbowsGarage Thanks for the response and suggestions!
Explain few more mechanisms especially *(NUBIKE leverage mechanism)* that will help me a lot.
Thank you.
I feel like the ape who just touched the monolith (...but now I have to learn Solidworks?) Seriously, I've occasionally tried to visualize how these mechanisms are designed for decades. Now, in 7:28, you've done it!
Thank you that was awesome!
Do you have a reference book or know of a set of lectures that explain the methods of forming all of the well know mechanisms?

Can you please do a video on torsion spring in assist mode mechanism
hey that was cool, I too wanted to learn mechanism designing in the software any idea from your side
What would the next steps? How would part 2 and 4 look like? These rotation points are way below the car chassis.
Awesome! Now I just need to figure out how to afford solidworks
Elegant! I wish I had thought of this. I feel dumb, but armed with this nalej, I can pretend to be smart XD
I figured out another solution. If your CAD software has 3 point arc or circle tool (I'm not familiar with Solid Works), you can find the location of each joint in bar 1 by drawing an arc (or circle) containing A1, A2, and A3 (and B1, B2, and B3). Perpendicular bisectors is probably what that tool uses "under the hood" to find the center of the circle. One nice thing about this method is that it does not clutter up your sketch as much (2 arcs instead of 6 lines). Another advantage is that it is self-explanatory why it works: bars 2 and 4 trace out the two guide arcs. Now, I can feel smart XD

The music could be a little quieter, otherwise great video.

The mechanism seems incredible I must confess but I really want to go deep in designing of mechanical systems. Can you mentor me sir?
Wow, an explanation I've been looking for all along. What software are you using in the video?
SOLIDWORKS is what I'm using.
That's with this principle that I am rethinking the mechanism of a piano.
can you explain starship food delivery robot "lid" opening mechanism?
