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
@@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.
@@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 for this video, very helpful 😊 Hooray for the long awaited return of Engineering How ❤️ Xxx
For the fan
Super helpful man. Thank you !
Thank you. Helped me a lot.
Super clear and concise!
I like the explanation which is very easy to understand

Thanks so much
Hi lepistes, Can you tell this calculation?
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
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?
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

@@FUJARAHEAD Okay, I get it now. Thank you!!

Which mass? Disk mass?
Assuming this is the total mass including the pulley disk.
@@sangn1696 ok bro
Wrong bro.. What about inertia of the wheel
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...
These calculations are completely wrong.
Could you show which ones?
Easy to say comments.
Prove it if wrong

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>
Wow... The number of errors on this video...
I'm novice to all this; would you explain which ones?
