Standing waves and frequency

AI Thread Summary
The discussion revolves around determining the largest possible fundamental frequency of a string fixed at both ends, given its standing-wave resonances at 325Hz and 390Hz. Participants highlight that the fundamental frequency must be an integer multiple of the resonant frequencies. The largest integer that divides both 325 and 390 is identified as 65Hz. This means that 65Hz is the largest possible value for the fundamental frequency of the string. The conversation emphasizes the importance of finding the greatest common divisor in solving such frequency problems.

1.) A string, stretched between two fixed posts, forms standing-wave resonances at 325Hz and 390Hz. What is the largest possible value of its fundamental frequency?

I have no idea on how to solve this problem, any assistance would be greatly appreciated.

Any frequency must be an integer multiple of the fundamental frequency. What is the largest integer that divides both 325 and 390?
 
would it be 65Hz?
 
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 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
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...
