Thanks once again for all the replies. I am starting to grasp the ideas now, but I still have one nagging issue that I would like to clarify. And to do that I will show a situation that tries to bring all of the ideas in this thread into a single problem.
So this is basically the classic pulley...
I got to a feeling that I have not properly described the setup that I am trying to solve here. The force F is not moving with the disc when the disc is rotating. The force F is essentially a rope that is tied around the disc and the rope is being pulled with a force that is equal to force F...
No, the laws do not state that. But this means that I am now even more confused.
Just to check that I have not made any algebra mistakes again, I will write out the equations where I add the external force F to the disc's 2nd law equation.
Disc:
##m _{1} a _{1}=F _{1} +F ##
Base:
##-m _{2} a...
Thanks once again for all of the replies.
I have updated the base diagram with the correct direction of the force F2 to show that it is equal in size but opposite to the force F1 that was showed on the disc diagram. And acceleration is still pointed in the same direction as is the disc's...
Thanks for the replies once again!
Ok so here is the diagram for the base and the disc so they are side by side.
I am probably overthinking this but I am confused as to what is the force that acts on the base. My gut feeling is that it should be the same force that acts on the disc, due to the...
Thank you for the answers.
First,
I understand the concern and I will use the provided equation when I get to the point where I need to calculate the final results.
Second,
I am a bit confused about free body diagrams and I hope that you can clear them for me. You say that the disc diagram...
I have had a thought experiment in my head for a while now and I am unable to find clear enough examples/info that deal with similar issues, to solve it on my own. This is why I hope that someone in this forum can at least point me towards a solution or provide hints as to where should I be...
