The hydrostatic water pressure acts only on one side and to a depth of 12 m from the top of a dock gate which is reinforced with three horizontal beams. (i) Calculate the load taken by each beam. (ii) Locate the positions of beams in order that each carries an equal load.
Dear Sir Firstly I would like to thank you. You are teaching well and concepts are very clear. It is a humble request that Please Make more videos about numericals of centre of pressure, meta centre and specially moment of inertia calculations with concept. Thank you so much sir!!!
As the depth of immersion of a vertical plane surface increases, what happen to location of centre of pressure ? Option a) fall closer to centre of gravity b) moves away from the centre of gravity
Sir,I watch ur video for most of my theoretical problems.But i face problem while taking note or screenshot (to take note later) because of the random movement of the camera.And while u r writing, it would be better for us if u give us some space to take down to note even for some second (so that we can pause the video). Thank u sir.❤
watch SOM playlist, also in previous semester u must have done that! First Momemt= Integration yda = y'. A :: y'= centroid distance, A Area Second Moment = Integration y^2da = Simply Moment of Intertia from the axis
Nhi kyoki jo Y hai wo distance from O hai, ek dandi agar kisi bhi angle pe inclined hai to y axis me dekho,, usko centro of mass hamesha y/2 pe hi rahega
Along the direction of plane the centroid will be at AC/2 consider the centroid is at the depth of h bar from the free surface you have AC/2 so by trigonometry you can calculate the h bar
Sir i have a doubt, as we know the fluid pressure increases as we go down so pressure force will also increase. Then how the pressure force right side the plane will dominate the left one to flow water from it?

Very helpful.. the way of teaching is too good! 👏👌
Thank you very much sir ji for a wonderful secction🙏🏽👍
Sir, how does the h bar equale to the h/2 in the numerical
Centroidal distance hota hai hbar. Isi liye h/2 aye ga

How the centroid of the immersed plane comes out to be h/2 ?
sir... 37:00 immersed Area to AB hona chahiye na....
kyoki limiting case me water B tak hi rhega
Total pressure of lamina?
Sir, moment of inertia is mass x radius of gyration square , its not area x distance square
As the depth of immersion of a vertical plane surface increases, what happen to location of centre of pressure ?
Option a) fall closer to centre of gravity
b) moves away from the centre of gravity
A
sir ,you are very helpful ..
sir, based on final expression of h*, can we say that if abody is getting submerged will it start roatating ???
No, it depends on centroid, for that body should be uniform like in this question body have same width of 1 unit throughout its length.
Sir u r looking awesome
Great job done... Heads off
Sir you r great always obliged to you
Thank u sir...vry nice explanation

Concept clear lecture
Moment of inertia of rectangle is bh^3/12 sir
sir you are legend.
Thank you sir ❤
Numerical well taught 👍🏾
Many many thanks sir.
The gate starts tipping at (h-3) metres. So the final answer is 9 - 3 = 6 metres.
Sir...how did u suppose its rectangle. For calculating moment of inertia....its not given in question...
the width is unity and the it's an inclined plane with a length. So it is a rectangle.
Sir ,
What is first moment of area and second moment of area???
Please explain in detail..
watch SOM playlist, also in previous semester u must have done that!
First Momemt= Integration yda = y'. A :: y'= centroid distance, A Area
Second Moment = Integration y^2da = Simply Moment of Intertia from the axis
sir ye plane kis tarah se rkha haia fluid ki andar kuchh samajh nhi aara ?? someone reply plase...

Thank you so much sir...
Sir in k subramanyam how to make on cubical tank question in force on plane surfaces please sir
Example no 2.26&2.27.
Can't we solve this problem this way:
Since the force should act at the hinge to level the gate, that implies that h/3=3 =>h=9.
H(bar) =h/2 hoga ya h/3 kuki triangle ka centroid h/3 hota h
Nhi kyoki jo Y hai wo distance from O hai, ek dandi agar kisi bhi angle pe inclined hai to y axis me dekho,, usko centro of mass hamesha y/2 pe hi rahega
Sir...ye moment of inertia...mass moment of inertia h..ya area moment of inertia??? Plis clear sir!!🙏🙏
Sir, when the plane is vertical below free surface liquid then the we take h bar =h/2.
So how you take h bar =h/2 in inclined plane.
Pls reply sir..
Along the direction of plane the centroid will be at AC/2
consider the centroid is at the depth of h bar from the free surface
you have AC/2 so by trigonometry you can calculate the h bar
Before the numerical I was ....🤔🤔🤔😴😴😴🙄🙄🙄😑😑😑😰😰😰
After numerical.....✅✅🤗🤗😳😳
Sir sin(thita) constant kyu liya
Sir, according to me
in this first example we should consider centre of gravity of the gate, if that is not hinged on centre of gravity.
Superb sir its tremendous lecture will u please start lecture of soil mechanics I m really so thankful
first tho thum ye seeklo bhai baad me kuch karo
Sir i have a doubt, as we know the fluid pressure increases as we go down so pressure force will also increase. Then how the pressure force right side the plane will dominate the left one to flow water from it?

F1 is due to h-3 depth of fluid where as f2 is due to only 3 m depth( in any case f1 might become more or less than f2)
Drag and lift and laminar flow sir...i cant find these topics
Sir or bhi subjects h like applied mechanics
Can u add subtitles? Because it will be useful for other language viewers
Sir kya chemical engineering wale dekh sakte hain kya yeh videos????
Sir how the h bar =h/2 in the problem 😕😕 plz ans sir
Y hai wo distance from O hai, ek dandi agar kisi bhi angle pe inclined hai to y axis me dekho,, usko centro of mass hamesha y/2 pe hi rahega
Bcoz h bar is measured from free surface not from inclined end of the plate

thanks for your help but can you please explain in english too?? thanks
Sir apne Jo 1st numerical kiye..usme ek tha ki "F1X1 > F2X2 " gate will tip ,
After this concept fir bole limit case main
F1X1 = F1X1
The gate will tip
Humko samajh main nehi araha hai..
Dono condition ek jese ho gaye?
Please describe
sir told that the limiting case f1x1=f2x2 i,e if f2x2 is greater than f1x1 then gate will tip... as u said f1x1=f2x2 gate will not tip here
sir total pressure and pressure head kya hota h sir ek videoo iske upr bhi banaoo plz
Sir ye sum mei niche ka pressure jyada hogga toh upar ka F1, F2 se kaam hi hogga so how we dominate that F2 pressure
sirf height = 9m then more hydrostaiccal pressure will apply on right side of hinge... i,e f2>f1
Nicely explained
Sir green marker se dikhta nahi h. .😥
Thankyou sir!!!
