Angular Simple Harmonic Motion of Wheel

AI Thread Summary
The discussion focuses on calculating the maximum angular speed of a balance wheel in an old-fashioned watch, given its angular amplitude of π radians and a period of 0.500 seconds. Participants express confusion about the relevant equations needed to solve the problem. A request is made for guidance on formulating an equation that connects the angle traversed, amplitude, time period, and elapsed time. The conversation highlights the need for clarity in applying concepts of simple harmonic motion to this specific scenario. Understanding these relationships is essential for finding the maximum angular speed.

Homework Statement


The balance wheel of an old fashioned watch oscillates with an angular amplitude π rad and period of 0.500 s. Find the maximum angular speed of the wheel.


Homework Equations


There are a lot of equations in this chapter and I don't even know where to start :confused:


The Attempt at a Solution


Like I said, I have no clue what I am doing

Maybe you could start by writing an equation that links angle traversed, amplitude, time period and time elapsed.
 

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...
