well, I was searching for this kind of explanation for a week and tried a lot of videos and searched for a lot of notes for a better explanation but this video does wonders and this was what I was looking for. Such a beautiful explanation which made the topic crystal clear. Again thanks a lot and keep doing this work.
I actually got a lot more than I thought I would out of this video, I can use a lot of this in combat robot and mining machine mechanisms For example A four bar lifter, A hammer, A drive rod style motor system that strengthens one rotational point via connections to other rotational points
Perfect, thank you. This & another video elsewhere has helped me to visualise how I can fabricate an automated swing leaf gate actuator. Very clean & well paced presentation.
Great !!!!!! sir it will be great if you will taught us whole Mechanics ..Sir it is great nd easy to understand. Sir will you upload whole playlists of Mechanics..it will help us much .....Sir Try to do it. Thank you so much for providing such beautiful content💝🙏🙏🙏love from India❤️💗🙏
Excellent teaching course and excellent narration, on your part, so I do not want to comment like a critic, for I'm learning this as your explaining it. However, when I got to the (15:29 time in the video) I had to stop and go back to the beginning when you explained about links and joints again, and seen where you circled the cylinder and called it a 4th link, that I feel I need to clarify what I think you really meant to say. I believe you meant to say the (crank base and the cylinder together as they are both grounded, forms the 1st link), then the crank the 2nd link , the connecting rod the 3rd link and the piston the 4th link. Please correct me if I'm wrong, but I just need to share this for clarification that I'm understanding this correctly, thankyou.
Hello sir, I have a question. I hope you could help me. Sir can you suggest a machine having a mechanism of four bar linkage with crank-rocker motion and the longest and shortest links are position opposite to each other?
Your example of a non Grashof linkage appears to be Grashof to me. The red link should be measured from the pivot points and therefore it appears to me that S+L
Hi Sir, how do define the cylinder which contains the piston as a linkage? I couldn't see why it is a linkage as I don't see any nodes in it. Could you help to enlighten me on my confusion? Thank you.
Thanks vou very much!! Very well explaned! ... I have a question ! At 22:14, in the lower mechanism... the torque that is inputed on the crank (little rotatory bar), is it amplified at the rocker (big rotatory bar) ? I mean... can i input a torque on the crank and output a higher torque by the rocker?? It has been days that im thinking about this and i cant come with the answare 😰😭
Yes. One condition would be called a parallelogram linkage (steering system of most cars) others would be a variation of crank and rocker configurations.
Sorry I missed this question. Zero degrees of freedom means you have completely restricted the movement. Imagine when you put a part in a fixture to machine it our gauge it, you're trying to hold it still.
From a non engineer but tinkerer, this was amazing. Been searching for fundamental explanations of these types of things for a while!
Thanks for watching, I really appreciate it.
I have an exam on kinematics tomorrow and you just made my life way easier! Thank you!
That's awesome! Good luck and thanks for watching!
This is one of the best explanations i have ever seen
Thanks for watching!
I can only wish that I have discovered this earlier during my LEGO years. Really appreciate the video!
Thanks for watching
This has been one of the most entertaining and educational half hours I've spent online in quite some time. Very interesting. Thank you very much!
Thanks! Looking back I start wondering if I should have broken it up into 3 shorter videos.
Just got my head refreshed from this vid. Thanks !

Thank you so much for this easily understandable and useful video!!!

it. Thank you so much for providing such beautiful content💝🙏🙏🙏love from India❤️💗🙏
I'm looking to get more mechanical design engineering experience and these videos are honestly super helpful. Thank you so much!
Thanks for watching!
Who knew that Andre Braugher knew so much about linkages. In all serious, nice video. Thanks.
I had to google him. 🤣🤣🤣
best video on the subject
Awesome info Professor, thanks for sharing your knowledge.
Thanks for supporting my channel!
Thanks for taking the time to make this video, great teaching style.
Thank you for this video!
Thanks for watching!
A good video and easier for learning, thankful
Thanks for watching!
i have learned alot of from this video
Thanks for watching!
@@infinitymfg5397 always welcome

Hello sir, I have a question. I hope you could help me. Sir can you suggest a machine having a mechanism of four bar linkage with crank-rocker motion and the longest and shortest links are position opposite to each other?
can you upload please more videos on linkage design? for example linkage design on graphical method
Your example of a non Grashof linkage appears to be Grashof to me. The red link should be measured from the pivot points and therefore it appears to me that S+L

Thank you, very informative video
But the music is really annoying it is better to keep it without music while explaining ( just an advice )
Do you think you could do some basics of robot flipper mechanisms
Thanks vou very much!!
Very well explaned!
...
I have a question !
At 22:14, in the lower mechanism... the torque that is inputed on the crank (little rotatory bar), is it amplified at the rocker (big rotatory bar) ?
I mean... can i input a torque on the crank and output a higher torque by the rocker??

Can we have two equal length for the four bar link??
Yes. One condition would be called a parallelogram linkage (steering system of most cars) others would be a variation of crank and rocker configurations.
What should we do when two links and two links are parallel
If the mobility (degree of freedom) for a mechanism equals zero, what is it called or mean?
then it can't move. It forms a rigid structure, such as in a pin jointed truss
Sorry I missed this question. Zero degrees of freedom means you have completely restricted the movement. Imagine when you put a part in a fixture to machine it our gauge it, you're trying to hold it still.
🔥💕👌👍
this is great
Thanks for watching!
Do you have the slide for share?
No, only on youtube.
Is this the Khan academy guy it sounds just like him
Naw man, I'm a different dude!
Nah, he sounds different than Sal
can I have the title of the background music?
24:51 To make
