Angular Frequency for Small Oscillations

AI Thread Summary
The discussion focuses on calculating the angular frequency for small oscillations of a uniform disk acting as a physical pendulum. The problem involves a disk with a radius of 4.4 m and mass of 9 kg, suspended from a pivot 1.364 m above its center of mass. The participant initially seeks clarification on the concept of angular frequency in this context. They later resolve the issue by researching the formula for angular frequency, which is w = square root of (mgd/I). The conversation highlights the importance of understanding physical pendulums in relation to small oscillations.

Homework Statement


A uniform disk of radius 4.4 m and mass 9 kg is suspended from a pivot 1.364 m above its center of mass. The acceleration of gravity is 9.8 m/s^2. Find the angular frequency w for small oscillations.

The Attempt at a Solution


I'm just wondering what does this question mean by finding the angular frequency for "small oscillations." Any help will be appreciated. Thanks!

If pushed slightly to one side, the disk would oscillate like a pendulum.
 
never mind. i figured it out. my professor didn't cover it yet but I looked it up. w=square root of mgd/I
 

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...
