Find frequency and period of oscillation

AI Thread Summary
To determine the frequency and period of oscillation for the given pulley system, the radius of the pulley is 2m and the moment of inertia is 10 kg/m². The calculated frequency is approximately 0.982 Hz, resulting in a period of about 1.01 seconds. The calculations involve analyzing the forces acting on the system and applying the principles of rotational dynamics. The user seeks confirmation of their results and a detailed explanation of the calculation process. The discussion emphasizes the importance of understanding the underlying physics to arrive at accurate results.

Homework Statement


Consider the pulley to be ideal. If the system disturbed from its equilibrium position by pulling the right hand mass down a slight amount and then released, determine the frequency and period of the oscillation. Radius of pulley is r=2m and I bar of the pulley is 10kg/m2.

I got f=0.982hz and T=1.01s

Is that correct?

Could you show how you got that?
 
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...
