what the fuk is this
Excuse me kind sir. How did your speed go from m/s to m/s^2?
He estimated required acceleration from rest. most likely how much time does it take to reach rated speed. 1s
nice

Nice 👌
Super clear and concise!
NO this is wrong... YOu didn't take into account the rotational inertia, and what's with the acceleration? how did you know the acceleration>
Great content. I have 420cc engine in my work shop, 14 or 15 hp. Spinning at 2500rpm. How can I work out crank toque from this, any help appreciated. Great content btw
I like the explanation which is very easy to understand
0.515
Complete wrong concept...we can't use radius of wheel like this...need to find the effective radius through the concept of moment of inertia...
Good night.okay I can use this calculation for servomotors .sou do brasil porto alegre.obrigado .I am from Brasil Porto Alegre
mass, where is the Power? How can you calculate torque without power of motor?
This is a great example. The unit for pressure is N/m² Please correct the unit.
Which mass? Disk mass?
Assuming this is the total mass including the pulley disk.

Wrong bro.. What about inertia of the wheel
wrong calculation
Super helpful man. Thank you !
Wow... The number of errors on this video...
I'm novice to all this; would you explain which ones?
@@MR-nl8xr 0.25mm=0.00025m
@@terryterry1655 Oh waow, yea, that's a problem.
you need an apostrophe in "motor's torque" and your illustration doesn't show any load on the motor. sucky video. why are all torque videos made by australians? accents are annoying speech defects. learn how to properly pronounce english words.
Hi lepistes, Can you tell this calculation?
These calculations are completely wrong.
Could you show which ones?
Easy to say comments. Prove it if wrong
@@anbarasuduraisamy6470 He should be using equivalent moment of inertia seen by the motor to calculate angular acceleration and torque....... The effect of gravitational torque only appears when there is an eccentricity on the load. The gravitational torque won't affect the pull out torque of the motor but can cause periodic centripetal force acting on the shaft causing vibration issues and lowering the life of bearing and shaft.
thank you
Thanks so much
Hello, how did you calculate speed which is 500 mm per second to 0.5 m per (s*s)
i think he meant acceleration since F = ma but i still don't get it how he found that value
@@moreblessingmushohwe6506 speed 500mm/s = 0,5m/s , formula for acceleration is a=v(speed)/t(time difference) so if we want to accelerate in one second its a=0,5/1 = 0,5mm*(s*s). at the begining was also confused.
@@FUJARAHEAD Okay, I get it now. Thank you!!
Thank you. Helped me a lot.
Great video thank you
Looking for this. Thanks for sharing
Thank you, straight forward :)
So for example a 50kg weight would depress the cylinder right? Should be able to calculate it backward too, to find out how much weight on an air cylinder creates how much air pressure? Like if i knew i had 10kg and i want to find out how much pressure it puts on the air cylinder piston.
Hi Tony. That’s correct a 50kg weight would depress the cylinder. If you want to work out how much pressure is on the cylinder you can rearrange the calculation. Pressure = Force / Area and this should give your answer. Hope this helps
Thank you I just did the math on my 63mm bore at 140 psi and it puts out 699 lbs of force.
Thank you for this video, very helpful 😊 Hooray for the long awaited return of Engineering How ❤️ Xxx
For the fan
can you explain more details that,area(m²)=(π x (0.0030m)²)/4.
Dear Sir............Example Problem I have a single acting hydraulic cylinder with a stroke of 300 mm, a bore of 18 mm and a rod of 10 mm if the press weight is 1 mm on the Piston Head what is the pressure.....Please explain the calculations
whats that in inches and pounds
Sir pump lpm change krke pressure de developed krsakte hai?
Nice
There is something I don't understand how did you find 423 ??
600,000 X 0.000706= 423.6 but he didn’t round so he left it at 423 and if you want to convert to pounds you multiply 43 by 2.2 which is 94.6 pounds of force.
What cylinder diameter for 3 tons weight? Pressure is 6 bar
Pressure does not have units of Nm^2
Kristoffer Gaard what do you think of this? www.sensorsone.com/nm2-newton-per-square-metre-pressure-unit/
@@justinwaugh8003 N/m^2 not Nm^2. If you're going to be an educator get it right.
When we say weight = 43 kg does it mean that it can push a block of 43kgs? How can i calculate force required to push a 20 kg object at distance of 3mm?
Correct yes, this 30mm bore cylinder will be capable of pushing a weight of up to 43kg vertically upwards. 20kg as a force is 196N Force (N) = mass (kg) x acceleration (m/s) 196N = 20kg x 9.8m/s Assuming you are using a slide to lift the 20kg weight 3mm then add 30% safety factor 196N x 1.3 = 255N Summary you need a cylinder with a pushing force of 255N
@@justinwaugh8003 hi , cylinder 32mm Bore 300mm Stroke , how many KG i can push with this cylinder?
@@manchette4840 assume using 10 bar because most of air compressors using 10 bars. d: piston diameter [cm] A : piston area [cm^2] p : operating pressure [bar] So, convert d to cm => 32mm = 3.2 cm use the formula F = p * A = p * 10 * (d^2 * pi / 4) = 10 * 10 * (3.2 * 3.2 * 3.14) / 4 =803.84 N divide by 9.8 to convert to kg =82 kg
Very informative video.
Great video!!
Thanks Lisa, did you learn anything?
Yes. I learned how to calculate the force of cylinders :)
