    I have been watching ur lectures since I was in 12th std and secured a very good rank in JEE mains and got my college also. Thanks, your videos helped a lot.

    Prof Michael I hope to help me in this problem please:
    "conical bowl filled with water, turn it so that it rests with its round edge on a table, and nothing has spilled out of it, prove that the pressure on lateral surface is equal to: 2/3pressure on base of this cone"

      Thats just a columm of water problem, so whats the colum height on its base and whats the colum height in the middle from left to right

    I am confused as to why you are able to substitute mass for area? specifically, why does the math allow this?

    • @MichelvanBiezen
      @MichelvanBiezen  ปีที่แล้ว +1

      If the mass distribution is uniform, then the mass of the disk is proportionate to the area of the disk. (twice as much area = twice as much mass).

    What allows you to use the Area instead of mass to find the center of mass?

    • @MichelvanBiezen
      @MichelvanBiezen  3 ปีที่แล้ว +1

      That is a good question. We can only use area instead of mass if the thickness and density is uniform, because then the mass is proportional to the area.

  • @gkj3427
    @gkj3427 ปีที่แล้ว +1

    I don't inderstand why we can use just Density x Area instead of Density x Volume?

    • @MichelvanBiezen
      @MichelvanBiezen  ปีที่แล้ว +2

      If the shapes have uniform thickness and uniform density, the the volume will be proportional to the area and we can use either to find the center of mass

      Okay I get it. This is not A Sphere but This is a Cylinder. If we use the volume equation of a Cylinder. Everything will be make sense.

    I thought you cant cancel terms across + and - signs when dividing

    • @MichelvanBiezen
      @MichelvanBiezen  3 ปีที่แล้ว +1

      As long as you divide every term in the numerator it is correct.
