Concept of DoF is well explained in this video lecture with help of animation of mechanisms. This video covers topic of higher pair, lower pair and mobility equation. Degrees of freedom of 4 bar linkage, cam and follower mechanism and 5 bar linkage are worked out here.

Understanding Degrees of Freedom
how easily you explained mate…thanks
Define static force analysis
03:45 you said 3 Lp but did the equation correctly. You helped me to understand it! Thanks
thnk u for the video, it is really helpful
mastered it with this one video! Thanks!
That's some quality content.. keep up the work..
finally can find a playlist without accent
i founf 4 DOF ( 6(3-1)-5-3-1 = 4 , -1 being for the Ball-ground contact, -3 for the the arm rotating into the ground, -5 for the pair between the two arms) for the 3D exemple at the end, is it right?
Pink sheep!!
i couldnt understand why only rotational degree of freedom in a plane … visualizing it makes it more understandable. great work!!
wow
good!
Thanks
Great video. Horrible voice. Please let go of the computerized voices…
No subtitles
in last animation i think DoF is one because all of another variables depend on rotation of first variable if the first variable rotate another variables should rotate so they are limited! who can help me understand the concept without formula thanks.
Thank you this vedio is helpful
Number of degrees of freedom of two particles connected by a rigid rod moving freely in plane_____________?

Thanks
It's really very helpful. Thank you ✌️
Thank you very much. It is very useful.
Whoah!!! I walked into the wrong room. lol
I don't get it, in the second mechanism, 3:41, you say it has 4 links and 3 lower pairs, but in the formula, you put down Lp=4, which one is correct and why 4? Thank you so much for your help!!
This man is totally confusing things and dictating things the individual bodies must have 6 degree of freedom how is he telling that it has 3 dof
in 4:12 i think its 4 LP and 1 HP
This channel is pretty good at explaining things. I really feel that if the channel owner were to hire a voice actor to narrate the video scripts, this channel would really flourish!
very nicely explained, for understanding numericals can visit https://youtu.be/fXPj7N5f6gA
Wow
It's this similar to the statistics population
more recent clarification for advanced students! – a rigid body can also have an additional DOF in that temperature or pressure can deform it's alignment or dimensions, so in some cases it can 7 DOF. we must take in to account it's environment which may without translation or rotation, incorporate any various twisting deformation in 3 planes
1:40 why would each link would have three degrees of freedom if they were not connected? If they were not connected they could rotate around the vertical axis and translate along the horizontal axis, what is the third one?
Thank you for the great video. Just a small correction: DOF is the MINIMUM number of INDEPENDENT variables dad describes the position of every point in the system.
2:40 to nitpick, the animation implies 2DOF as it is a cylinder joint that can rotate and still has space to slide along the rod
I couldn't get the 3rd no. what is the physical meaning, as we can see the wheel can rotate in a rotatory axis. On the other hand, the body is moving towards the z-axis. we have found 2 degrees of freedom, but the calculation is saying there is 1. What's wrong am I doing?
But the video was tremendous, the level of thinking of the creator is beyond the expectation.
