Got it. Thanks for your help.

When the radii of the outer pulleys are the same and they are at the same height, I am quite sure that the angles must be and will stay symmetric, till the angle eventually becomes zero when the weight is lifted up totally. When one of the outer pulleys is installed at a higher height and the...

The magnitude of the tension force in the rope must be equal on each side, thus, it seems to me that each outer weight is equal in magnitude to the tension force in the rope at each side. However, since the middle pulley is not making a symmetric angle with the rope at each side, and because it...

Thank you for providing directions. I was having some difficulties with defining what terms I had to search on (as I am fairly new to physics). At the moment, I am searching on "static pulley equilibrium" and I think that must help me out. Do you think I am on the right way? Do you have...

I get the point, however, I have some doubts about whether or not those findings also applies for the echelon arrangements depicted in my illustration. Since I remind from the other link (https://www.hpcwire.com/2018/07/05/aerodynamic-simulation-reveals-best-position-in-a-peloton-of-cyclists/)...

I went through the info about the eddies, nice to have learned about that as well. Its a difficult decision, considering all the info, but I think I will go for B as my final answer for the particular echelon setting with all the info I have been able to gather till now. Any of you, who is...

I have been being busy with searching on rotational motion today. Since I am pretty new to this subject. I think I need some time to understand all the principles and factors effecting the rolling motion. So, I beg your pardon if my understanding does not go that optimal yet. Anyway, with my...

Homework Statement I had to answer which of the pulley arrangements illustrated (see picture) is in equilibrium (the drawing went a bit difficult, please see all outer boxes as equal in size and the middle ones as well) I managed to answer that it is arrangement C, by finding out that...

@haruspex Regarding relationships between 3 variables I obtained information about relationships among three variables and I realized that I indeed appear to have made a correlation-related misinterpretation/mistake. So, basically, if you have a fomula like f “Ffriction*R = I * R", you cannot...

Thanks a lot for your views and the nice explanations @256bits , @Ekooing and @boneh3ad Tomorrow, I will read through the info provided with the link and try to gain some more knowledge on terms like "eddies" and "stokes flow and try to link it to answering my question, and come back it it here.

First of all, thanks everybody for the directions. Hereunder my refined assumptions based on your input: Regarding the relationship between torque and moment of inertia: @haruspex Applying your analogy to my topic question, it would mean that the torque should be seen as a constant (?) and...

@haruspex You're right, it had to be "angular acceleration" The friction Force is responsible for causing the torque. The friction force can be defined as normal Force x static friction constant. And the magnitude of the normal Force gets larger with mass. Therefore, it seems to me that...

Firstly, hi and welcome! Thank you for your input, every new view helps me in strengthening my general look at the subject, thus I am thankful for it. I had come across the same theory for in-line constructions. However, I really wonder about whether or not the same of what you described is...

Homework Statement If two balls, being identical in volume, but different in density (one ball is made of iron, the other of aluminum) roll down from an inclined plane, which will reach the bottom first and which will cover a larger distance after having reached the bottom? IMPORTANT NOTE...

Thanks a lot! I think its proper ethic to do so if you expect guidance/help, so I do my best. I will absolutely go behind it and come back at it here. I still doubt between the last and mid one, but after having slept a night over it, I think I GOT IT :) ! I feel more inclined towards the mid...
