Pulley System: Solving for Acceleration (a3)

AI Thread Summary
The discussion revolves around a pulley system where one pulley is massless and the other has mass m3 and radius R. The user is confused about the acceleration of the pulley (a3) and whether it equals a2 or a1. Clarification is sought regarding the relationship between the masses m2 and m3, as they are attached in the system. The conversation highlights the importance of understanding the connections in pulley systems to solve for acceleration accurately. The exchange emphasizes collaborative problem-solving in physics homework.

Homework Statement



Hey guys.
Look at this pulley system, I wrote down all the equations.
The pulley on the left is massless, the one on the right has the mass of m3 and radius R.
I also wrote the the torque equation of the pulley and the thing I don't understand is the what is the acceleration of the pulley (a3), is it equal to a2 or to a1?
Thanks a lot.

Oh, you right...:blushing:
Thanks.
 

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...
