Extreme situations in physics problems

AI Thread Summary
Extreme situations in physics problems often involve conditions where standard forces become zero, such as losing contact with the ground or when a rope goes slack. Other examples discussed include black holes, parallel voltage sources, and tension in a perfectly horizontal string. These scenarios are considered extreme because they challenge typical assumptions and lead to unique behaviors in physical systems. The term "extreme" may be more accurately described as "limiting" or "ideal" situations. Understanding these concepts is crucial for solving complex physics problems effectively.

"Extreme situations" in physics problems

I don't know if this question is pertinent for this discussion forum. I was making some study notes, and i was trying to recollect statements that are always "extreme" in physics problems (such as mechanics). Until now, i have found two of them: Lose contact with the ground (the normal force is 0), and rope goes slack (tension force is 0). I was wondering, are there any other "extreme situations" that i should be aware of?

Thank you very much for your time.

Why are those examples considered extreme?

What about..

Black holes?
Two different ideal voltage sources connected in parallel?
The tension in a perfectly horizontal string?

I think there may be a language issue. Probably what the OP means is "limiting" or "ideal."
 

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...
