Problem with angular acceleration and Moment of Inertia

AI Thread Summary
The discussion centers on the need for clearer problem formulation regarding angular acceleration and moment of inertia. One participant emphasizes that without a well-defined question and supporting figures, it is difficult to provide assistance. The original poster acknowledges the difficulty in articulating the problem and decides to abandon the topic due to time constraints. The conversation highlights the importance of clarity in seeking help for technical issues. Ultimately, the original inquiry remains unresolved.

There is nothing to answer anymore. I have no time left for the project to use the data.

Your problem is ill-defined. To get help, you need to formulate it more clearly and, ideally, include a figure. Look at the other posts seeking help and you will see what I mean.

I get what you mean.

It's a little bit to hard for me to describe and i don't have enough time to work on it anymore so I discard my previous post and this topic will be made unrelevant using a different title. Thanks for your potential help anyway. :)
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
