I am thoroughly convinced that all of the complexities of math/science can be simplified when you break it down with concrete examples and simple vocabulary. Thanks for the video.
I have been teaching myself fluid mechanics for some time, however my understanding of fluid pressure wasn't quite there yet. After watching your tutorial my understanding has advanced greatly. The best explanation of pressure I have seen. I am now a subscriber. Thank You.
Brilliantly explained. Both thumbs up for this video. I wish all math and other math related subject teachers explain math theories like you. Thank you so much for this wonderful video.
@@apprenticemath if we remove the sq inch block , and just put the weight , will the surface area of the weight in contact with the table be considered then
I believe 'per' could be basically equivalent to 'for each' You might be going 20 miles for each hour that passes. Though I assumed it was one of the countless words English has absorbed and that most would understand it...
Does that also mean the larger the diameter of a duct/pipe, the lesser the pressure will be? meaning if you attach a larger hose (in diameter) to a pump, it will reduce the pressure.
I have question with this 1 meter there is nanometers and micrometers of areas are they experiencing the 1 pound of weight on them or that 1 pound is divided into every single nanometer of area so each atom experience a force of that weight equal to the neighboring atoms Also what happenes if u shift this pound slightly to the left or right ty Your explanation is very fantastic sir now intuitively I understand it im surprised many many people don’t understand it i asked many to check for comprehension no one really knew
Every atom over that square bear a tiny portion of the 1 pound, equally. If the 1 pound is resting on a table, the whole table bears a tiny portion on that 1 pound, but not equally. The atoms directly under the pound bear most of the weight, the other atoms help a bit too. It's like standing on a trampoline mat, the whole thing bears your 200-or-whetever pounds, the mat stretches everywhere, but directly under your feet is where the stretch is greatest
@@apprenticemath so every atom experience the weight of the pound but not equally because atoms have intermolecular attractive forces so neighboring atoms pulling on each others but how do u calculate the weight distribution since its not uniformly distributed
Nice explanation however, it's not a one pound "mass" ( 2:15 ) it is a one pound "weight". An important distinction because pressure is force (weight) per unit area.
Right. Since 1 July 1959, the international avoirdupois pound (symbol lb), defined as exactly 0.45359237 kg is the unit of measure of mass. Weight is related, a force exerted by a mass of 1 lb, known as one pound-force. Pressure under a 1 lb mass at sea level STP accelerating at 32.174 ft/s2 (9.80665 m/s2) against the surface of 1 sq.in is 1 psi by definition.
+apprenticemath Exactly! One must be careful to say pound-mass (lbm) so as to avoid confusion with pound-force (lbf). Otherwise if pound alone is used it is assumed to be, and generally understood to be pound-force even though one pound-mass weighs one pound-force. Nice video, I had considered making one similar myself.
small doubt sir you mean how you select tiles sir ? is this common ? you mean one psi means the pressure obtained in the bottom tiles is called one psi
this is what I'm trying to understand bore the diameter of the cylinder is called the bore. the larger the bore the greater the area on which the gases have to work. pressure is measured in units such as pounds per square inch (psi). the greater the area in (square inches) the higher the force exerted by the piston to rotate the crankshaft. the harded it is to turn the piston up to compress the air fuel mixer? or the easier it is for the pressure to move the larger area ?
this is assuming the weight is symmetrical and covers all square tiles evenly. what if a 1 lb weight completely covers 3 squares and only half of the 4th square?
Nothing to assume, everything EXACTLY as shown. Nothing was said or shown about symmetry, balance, center of gravity, weight distribution or anything related and the whole tile was covered pretty clearly repeatedly. Likewise, do the math exactly as shown.
totally wrong, psi means by definition pound-force per square inch lbf / in2. This video is about lb / in2 which is not a unit of pressure but mass / area.
Not happening. Table has all the pressure of the tiles plus the weight. 1 tile = 1oz. = 0.035 lbOn top of the top tile = 1 psi On top of the second tile = 1.036 psi On the table under the stack = 1.071 psi
I have never seen a guy who can explain these things in a better & easy way like you, You're the best, Thank you SO MUCH
Ikr lol..great content 👍

Now I clearly understand it, thank you!
Excellently explained, thank you
simple but brilliant!
Brilliant video. Even my sisters and niece could understand this!
Thank you for this!
Great video. Thank you
Simply Beautifully explained! Thank you
Glad it was helpful!
Congratulations!! You have been Selected as a senior Engineer in Harvard University.
Hahahha this was uploaded 5 years ago. But you really made my day!! You explain it better than the others!:-) thanks!!!!
No worries, mate. Math & physics really dosn`t change much since it`s described, some stuff is unimproved upon since 2500 years. Psi is the same.
@@apprenticemath if we remove the sq inch block , and just put the weight , will the surface area of the weight in contact with the table be considered then
nice it is a good teaching method. love it
Very cleary explaination sir. Thank you 👍
Awesome explanation 👍🤓
wow man 2021 I am watching this video and learned in 3 minutes thanks
Cheers, mate!
No wonder earthbound had psi and people thought it was physics
That was very useful! Thank you!!!
very nice explanation. thanks!!!
Thank u so much sir....it was owsome... I never like b4 ... but I am shock u uploaded 5 year ago...
Great video
WOW. Great job
Thank you. Clearly explained
Yas! I finally get it - Thank you
Very good explanation 👍
great explanation !!
Thank you!
great work i understand now
Very claer to understand 👌
very beautifully explained, keep it up
excellent explanation
Glad you liked it!
Great explanation 👍
Very nice way to explain
It just seems so old fashioned!
GREAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAT EXPLAINATION ..
THANK YOU
Now I understand... wow this is like magic
Fantastic, Very easy..!
Nice knowledge vedio thank you sir

Also how u know the weight of that thing is 100% homogeneous means it’s distribution is equally through its matter
I can finally imagine a Single Psi of force i wasnt able to. Since im not from U.S
Beautiful!
Well said
very nice explanation
Thanks, I now understand it :)
Thank you

Thank u boss
Thank you sir,
THANKS SIR....................
clear explonation
small doubt sir you mean how you select tiles sir ? is this common ?
you mean one psi means the pressure obtained in the bottom tiles is called one psi
Right, 1 lb evenly spread out over 1 in2
Thank youuuuu!!!!
this is what I'm trying to understand
bore
the diameter of the cylinder is called the bore. the larger the bore the greater the area on which the gases have to work. pressure is measured in units such as pounds per square inch (psi). the greater the area in (square inches) the higher the force exerted by the piston to rotate the crankshaft.
the harded it is to turn the piston up to compress the air fuel mixer? or the easier it is for the pressure to move the larger area ?
Harder, valves are closed, piston is moving against the pressured gases. Needs a heavier flywheel. Or shorter stroke to compress 10:1, 13:1
this is assuming the weight is symmetrical and covers all square tiles evenly. what if a 1 lb weight completely covers 3 squares and only half of the 4th square?
Nothing to assume, everything EXACTLY as shown. Nothing was said or shown about symmetry, balance, center of gravity, weight distribution or anything related and the whole tile was covered pretty clearly repeatedly. Likewise, do the math exactly as shown.
it's very simple my dear the psi is = 0.29
very nice
Thanks.
Doesn’t the square inch weigh something? 1lbs + square inch device = square inch??
Weighs nothing, forget the tile and device, it's an imaginary square.
still good 👍
totally wrong, psi means by definition
pound-force per square inch lbf / in2.
This video is about lb / in2 which is not a unit of pressure but mass / area.
nice
What if the 2 squares where stacked on top of each other, with a 1 pound weight on top? would that be .5 psi then or would it be still 1 psi?
Still 1 psi even if its atop a mile tall stack. Pressure halfway down or at the bottom of the stack is entirely different.
So if 2 squares are stacked together with a 1 pound weight on top, the table might only have a pressure of like .5 pounds on the table?
Not happening. Table has all the pressure of the tiles plus the weight.
1 tile = 1oz. = 0.035 lbOn top of the top tile = 1 psi
On top of the second tile = 1.036 psi
On the table under the stack = 1.071 psi
ok that makes sense thank you for that information
thank u
My prayer Jesus may bless you and give you good health love from India
Wat about 1 inch in height . so 1in sq. Is all sides height ,width, and length. Like a cube not a square tile. Right!!! Or am i wrong?
On such a cube, also 1 psi.
Finally i got it
