awesome video !

Can someone please explain something to me? We know that pressure acts perpendicular to the surface. Thus, the force that exerted on the wall should have both the components of x and y. But in the video, it seems to me that he only considered the weight (y-comp) of the fluid but not the x component that the fluid exerted on the wall. The only x component considered is that of the external pressure by the surrounding fluid, but not that of the fluid body in question. In the y direction, we have F1 and weight, in the x direction we have F2 only. Are we not supposed to have another force in the x direction?

perfect! this makes it all so clear, compared to what my professor was doing. thanks! :)

Thanks a lot, its awesome

what if the magnitude you are trying to find is the water force over the length of the wall from the top of the surface to the bottom? That is the point where it is very confusing to me.How can you instantly tell that oh Im gonna use Rx=Px(A) for the horizontal component and Ry=(density)(g)(Total Volume)? How can you draw the FBD for what it is asking? Im reading different books to take the Mechanical FE and in one book it explains the average pressure of Px=(1/2)(density)(g)(h1+h2) however in the FE manual it doesn't dictate the *average pressure formula. So how do you know when to use it at a certain component?

If a circular plate and a square plate of same diameter and side "D" m are lying vertically in such a way that their center are "D" m below the free water surface. Find out the ratio between the total pressure and centre of pressure between the circular plate and the square plate.

what happens if you flip the figure?

Hi, I want to ask that when you mentioning the weight, which weight are you considering, (a) the one for the isolated body of water or (b) the one above the isolated body of water. And if it's (a) how do we find the volume of the that shape that has such dimensions.

Why Fh and Fv have same line of action

@krishanveer8199

6 жыл бұрын

Max Payne bcoz fv is balancing the net force of F1 & W and hence will act between their line of action . And for Fh, since it is only balancing F2 , therefore it will act in the same line of action as Fh.

Is there force exerted by atmospheric pressure in the vertical direction? If not why?

@CPPMechEngTutorials

7 жыл бұрын

Yes, but the atmospheric pressure is approximately constant around the entire system. So the downward force on the free surface is balanced by a similar upward force on the gate. The atmospheric pressure forces cancels out, so we ignore it.

Gazi Gn he has calculated Fh by multiplying pressure with area and Fy by simply the weight (weight itself is a force u don't need to multiply it with area) carried by the surface.

Does F2 and Fh always occur in the same line of action? Thanks for the lesson.
