What is the Solution to a Rotational Motion Problem?

AI Thread Summary
The discussion focuses on solving a rotational motion problem, with a specific emphasis on the conversion of units. Participants point out that the original poster failed to convert 3000 rpm to radians per second correctly. Although the poster claims to have made the conversion, others clarify that the conversion from revolution rate to radian rate was not properly executed. The issue appears to be resolved after addressing the necessary conversions. Accurate unit conversion is crucial for solving rotational motion problems effectively.

You forgot to convert 3000 rpm to radians/s.

No haruspex,

I have converted it in the second last line.
Please see.

Looks to me like you converted rpm to revs/sec, and you converted n revolutions to 2nπ radians, but I don't see any conversion from revolution rate to radian rate. (The pi's should cancel.)

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...
