Forces on Curved Surfaces Trick [Fluid Mechanics #52]

[@guitarz1egendz]

Well played sir, I was reviewing my subjects and thinking why Fv's volume is outside of the curved surface. You sir have enlightened me.

Why did you not take into consideration the force on B when using this method? In your last video, while using this method you kept the forces (Ay Ax and B) on the gate. Why did you not keep B on in this case?

5:29 can u please explain what is the source of the pressure distribution from the bottom and the left hand side, in fact there is no water in these sides.

[@hasindupiyumantha3595]

Nice trick. Thanks a lot

[@SujalRajput10]

Interesting trick, definitely can save a lot of time.

[@funfaithchannel6477]

Thanks for all your videos on fluid mechanics. Please I honestly don't understand how you got 4r/3π. Please can you break this down for me?

[@saintpeter1802]

Hello teacher could you help me to solve a problem of hydrostatic force of submarine ?

[@MShazarul]

What if it's a semicircle? Looks like F_V cancel each other out

[@primoperez805]

How to you find FP1?

[@kevin15664]

Fp1 is just Pressure x Area, or GammaFluid x h x area or Rho x g x h x area

[@kevin15664]

just realized this was a year late. sorry buddy

[@snowpro5ryusmc]

How do you find Fp1?

[@qKssL]

Easiest solution is finding the weight of the liquid above the surface. So you ought to substract the volume that spherical surface occupies (i.e hepispherical volume in 3D case) from the total volume (i.e a cylinder in 3D case).

you are a champion

[@DzahierulAliemy]

Thank you

[@---js1vv]

Thats smart, Thx.

[@ahmadeldesokey9844]

Nice videos

[@eisleyism]

There is no water pressure at Fp2.

[@Sokar599]

very nice thanks

[@aelxsiirde9285]

hi. im kinda confused. how did you know that Fp2 is a triangle?

[@achillesheel12]

Pressure varies with depth due to the hydrostatic law p=row g h

[@funtimes6797]

With the increase of depth pressure increases

[@joon.p271]

great

[@akshaysalaskar5578]

waste of time

your body is a waste of space
