Solving the Violin String Problem: Frequency, Wave, and Tension

AI Thread Summary
The discussion revolves around solving a physics problem related to a violin string with a mass of 35g and a length of 60cm, vibrating at a frequency of 196Hz. Key questions include determining the frequency change when the string is fingered at 15cm, calculating the wave propagation speed, and finding the string's tension. Participants express confusion about how to apply the relevant equations, such as the wave speed formula and the relationship between tension and frequency. There is uncertainty about the necessary information to solve the problem effectively. Overall, the thread highlights the challenges in applying theoretical concepts to practical scenarios in string physics.

Homework Statement


Mass of violin string = 35g
Length of string = 60cm
Frequency = 196Hz

What is the frequency change to if the string is fingered at 15cm from the top end?
How fast does the wave propagate down the string?
What is the tension in the string?

Homework Equations


v = Squareroot of (Tension Force / (m/L))
vT = wavelength


The Attempt at a Solution


No idea how to approach this problem.. Not enough given information to plug and chug into those equations.

I think the frequency change would be higher? But I'm not sure how to figure out the tension, velocity, or wavelength.
 

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...
