Sinusoidal Oscillator Quick Question

AI Thread Summary
To set up a standing wave with 5 segments on a string driven by a sinusoidal oscillator at 100 Hz, the velocity can be calculated using the formula fn = nV/2L, where fn is the frequency, n is the number of segments, V is the velocity, and L is the length of the string. However, additional information, specifically the total length of the string, is necessary to isolate the velocity variable. The discussion highlights that the behavior of the standing wave on a string fixed at one end resembles that of a pipe closed at one end and open at the other. Without the length of the string, the velocity cannot be determined. Accurate calculations require all relevant parameters to be known.

Homework Statement


Drive one end of the string with sinusoidal oscillator of frequency 100hz. What velocity is required to setup a standing wave with 5 segments?


Homework Equations


I know for standing wave that fn = nV/2L and you can isolate out velocity variable.


The Attempt at a Solution



Though I'm not very familiar if the string is not tied down at both ends and I was wondering if someone could explain how to obtain the velocity from the 2 givens.

You don't have enough information. You also need the total length of the string.

The standing wave in a string fixed at one end and free at the other end will look the same as in a pipe closed at one end and open at the other end.
 

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...
