AI Thread Summary
In a cylindrical space station rotating with constant angular velocity, the angular acceleration is indeed zero. This is because constant angular velocity implies no change in the rate of rotation. The astronaut, located at the perimeter, experiences this constant motion without any angular acceleration. The discussion highlights the distinction between angular and linear motion, but confirms the initial understanding that angular acceleration remains zero in this scenario. Overall, the concept of angular acceleration being zero is affirmed in the context of constant angular velocity.

Is angular acceleration zero in this situation?
A cylindrical space station located in distant space, rotates with constant angular velocity about its axis. An astronaut rotates with the station and is located at the perimeter, a distance R from the axis.

Sure sounds like it to me. (It says 'constant angular velocity'.)
 
Doc Al,
Thanks for your response. I'm pretty confident in that answer as well. However, I began second-guessing myself because everything seems to different when it's angular and not linear.
 

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...
