AI Thread Summary
The discussion centers on solving for unknown masses in a mobile system in equilibrium, specifically focusing on the relationships between the objects' distances and weights. Object B is given as 0.735 kg, and there is a suggestion that the distance labeled as 15m should actually be 0.15m. Participants emphasize using the law of leverage to establish balance, indicating that the weight of object B must equal the combined weights of objects C and D. The conversation highlights the importance of accurately interpreting the distances in the mobile setup to solve for the unknown masses effectively. Understanding these principles is crucial for determining the equilibrium of the system.

Alright pretend this is a mobile in equilibrium. I'm given that object B is .735kg and i need to determine the masses of the other ojects...

Hi ratt10mm,
15m looks wrong, isn't it rather .15m?

Anyway, you know the law of leverage, plus you know that B must be balanced against C+D. That's where to start, I think.

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...
