Angle and Frequency in Horizontal Circular Motion

AI Thread Summary
As frequency increases in horizontal circular motion, the angle below the horizontal decreases. This is attributed to the increase in speed, which affects the forces acting on the object. To analyze this relationship accurately, a free body force diagram is essential. By incorporating the angle into the forces, one can derive a formula using F = ma. Understanding these dynamics is crucial for solving related problems effectively.

Homework Statement



What happens to the angle below the horizontal as frequency increases? (in horizontal circular motion)


Homework Equations




The Attempt at a Solution



I think that it would decrease, because your speed is increasing, but I don't know if I'm right

Good instinct on the speed, I think, but you really need a formula for the angle so you can tell for sure. I would begin with a free body force diagram for the object in circular motion. Show the string at an angle A so the A will be included in some of the forces so you can get a formula for it using F = ma.
 

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...
