I did few more experiments with bearings in the pulley. But not much of a difference. With latest experiments using 2 pulleys, I am seeing that wt. required on other side of pulley to start acceleration, is close to twice the wt. on one side. So if wt. is x kg on one side then I need to put ~2x...

As I think more, I tend to agree with you. Initially I neglected bearings but bearings are probably must. As I increase weight, there is more tension in the rope and that in turn adversely affecting load on shaft. Having bearings shall probably help convert this load into rotational force, which...

As I am doing a prototype, to cut on cost, I used very simple pulleys. Hence my pulleys have no bearings. Now when I use wt of 0.5 kg, I had to put 1 kg. So I am assuming I had to put extra 0.5 kg to accommodate all the deficiencies of cheap materials used. So next time when I take 2 kg, I would...

Hi, I am a EE post graduate and semiconductor (chips) professional with 17 years of experience. Over years I have lost touch with real world physics and now got interested in Physics due to some research project I am doing. Thanks Raj

I have an Atwood Machine. I have an aluminium Pulley of radius 4 inch. A gym cable running over it. Not sure coefficient of friction but smooth movement. One end of rope, I attach wt. of 0.5 kg. I had to attach weight of 1 kg for acceleration to start. If I attach 2 kg, I had to attach 3.1 kg...
