    Sir in the last numerical of this leacture the steel submerged between the interface of hg and water, why the force due to buoyancy is not providing a downward force by the water on the surface of steel block?

    • @khanshahid9559
      @khanshahid9559 5 лет назад +1

      bouyoncy means upthrust force and upthrust acts in upward direction.......

    • @AkibJahangirChoudhury
      @AkibJahangirChoudhury Месяц назад

      Watch the lecture carefully. Sir already mentioned in the beginning of the lecture “Net Vertical Component”. Also you can see in the derivation why upward force is taken.

    @hilloldas9074 5 лет назад +5

    SIR , in the first case when B is below G , the moment due to the weight and buoyant force are in clockwise direction same as the external moment. But if we take the external moment in anti clockwise direction then even if B is below G the body will resist the external moment and we should get stable equilibrium.

    • @rohitjamdagni9926
      @rohitjamdagni9926 3 года назад

      Bro you can draw diagram by your own for both condition, you can see that if external force is anti clockwise the moment due to weight and buoyant force will also get in anti clockwise direction , so it will be unstable equilibrium (if B is below G) either your external force is anti clockwise or clockwise

    • @AkibJahangirChoudhury
      @AkibJahangirChoudhury Месяц назад

      ⁠​⁠@@rohitjamdagni9926yes absolutely perhaps the boy above didn’t verify it through diagram. You are absolutely correct that if we take the external moment in anticlockwise direction then the moment generated by the G and B will also be in anticlockwise. As a result of which an unstable equilibrium condition occurs.

    Hello sir,
    hope u r doing well
    At 26:31
    In the last problem, you added the buoyant forces(Fb1+Fb2=W).
    My question is, the body is has water above it putting pressure downwards.
    Then how can the forces be unlike force(The water is not putting any upwards force).
    Or am I wrong here?

    • @AkibJahangirChoudhury
      @AkibJahangirChoudhury Месяц назад

      The term Net Vertical Component of Hydrostatic Force comes into play. The upward force will be dominant than the downward force.

    Hello sir, please explain the concept behind this problem:
    A wooden log (S.G=0.7) has a cross-section of 300mm*300mm and is 2.50 m long. It is required to float vertically in water and for this purpose it is proposed to fasten a lead prism of cross-section 300mm*300mm to the bottom of the log. How long should be the lead prism (S.G=12) to make the log float with 0.5m length out of water?
