He estimated required acceleration from rest. most likely how much time does it take to reach rated speed. 1s

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...

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.

@@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.

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.
@justinwaugh8003

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

@justinwaugh8003

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
