Frictional Force: Causes & Effect on Rotational Flywheel & Pulley

AI Thread Summary
The discussion focuses on the frictional force experienced by a rotational velocity apparatus, specifically in relation to a flywheel and pulley system. Key points include the need to explain discrepancies between theoretical and experimental data in a lab report. The frictional force arises due to the axle pressing against the flywheel, generating resistance. Understanding these causes is crucial for accurately interpreting experimental results. Overall, the conversation emphasizes the importance of analyzing friction's impact on rotational dynamics.

Hi guys currently submitting a report for a lab experiment we carried out in college. This was to determine the frictional force of a Rotational Velocity Apparatus.

I have successfully carried out the relevant calculations and in conclusion to my submitted report, I have to explain the differences in theoretical and experimental data.

I am looking for any help or guidance with regards to explaining the causes of frictional force on the rotational fly-wheel and pulley.

the axle presses on the flywheel (you must have encountered some resistance) so a friction develops
 

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'

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...
