    NOW I HAVE THE CONFIDENCE TO FACE THEORY OF MACHINES. YOUR EFFORT HAS MADE SO MUCH CHANGES IN MANY OF OUR MINDS. THANK YOU SOOOOO MUCH.

    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!

    03:45 you said 3 Lp but did the equation correctly. You helped me to understand it! Thanks

    i couldnt understand why only rotational degree of freedom in a plane ... visualizing it makes it more understandable. great work!!

    It's just a five minute video.. But i learnt so much from this video that i couldn't understand by self-studying for several hours... So, Thank you, who ever uploaded this video😍😍😍😍.... The voice was not a problem for me 😃

    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

  • @xerenityapexlegends3940
    @xerenityapexlegends3940 3 ปีที่แล้ว

    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

  • @buttiraviteja5351
    @buttiraviteja5351 2 ปีที่แล้ว

    In slider crank mechanism, one crank angle is sufficient to define the position. So DOF of slider crank is one.

  • @mehran1384
    @mehran1384 3 ปีที่แล้ว +1

    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.

    Thank you very much for such an wonderful video....I have a doubt....We all know that superstructure has a negative degree of freedom....But could you please tell me the physical significance of the same or site an example??????

    • @simhishh
      @simhishh 8 ปีที่แล้ว

      what kind of significance brother the more the increase in negativity the more the blockage to its motion ,
      thats why almost all the airports have curved structure with pillars having -80 degree of freedom.

  • @tithimazumder6138
    @tithimazumder6138 3 ปีที่แล้ว

    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.

  • @Troynjk
    @Troynjk 2 ปีที่แล้ว

    How many degrees of freedom an object can have at the same time? For example, a sphere is spinning clockwise and moving forward at the same time, i.e. it’s using 2 out of 6 degrees of freedom, can it have more?

  • @emreyilmaz9384
    @emreyilmaz9384 3 ปีที่แล้ว

    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?

  • @alexbourlis
    @alexbourlis 6 ปีที่แล้ว

    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?

  • @thewakakeboarder

    • @EkForeigner
      @EkForeigner 9 ปีที่แล้ว

      I have a question.....
      if one rigid bar in space(3D) with one end fix than how many degree of freedom

    • @arunm9859
      @arunm9859 9 ปีที่แล้ว

      +hiren kachhadiya it's zero , because you fixed the bar. so it cannot be moved. you have constrained all the dof of the bar by fixng one end.

    • @krzemian
      @krzemian 8 ปีที่แล้ว

      +Arun M unless by fixed he means fixed in position but able to rotate (like the base of a crane), then it's 2 DOF

    • @arunm9859
      @arunm9859 8 ปีที่แล้ว +1

      There are two cases.. one you can fix one end. Which means no degree of freedom is permitted.
      Or you can pin one end. In that case it will be having rotational degre of fredom

  • @BrokenHeart-nw5fu

    • @ShauriePvs
      @ShauriePvs 7 ปีที่แล้ว

      2lp doesn't mean 2 lower pairs...'lp' represents no. of lower pairs and '2' represents that it restricts 2 degrees of freedom

    • @BrokenHeart-nw5fu
      @BrokenHeart-nw5fu 7 ปีที่แล้ว +1

      Shaurie Pvs thanks
      and why there is 3(N-1)
      why can't be like 3(N-1)/3(N-3)or only (N-1)

  • @mehdirostaee2828
    @mehdirostaee2828 5 ปีที่แล้ว

    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.

    • @mehdirostaee2828
      @mehdirostaee2828 5 ปีที่แล้ว

      maybe Middle triangle doesnt depend on first joint so its depend on what? in last animation!
