    String Vibrations
AI Thread Summary
A standing wave is established in a 120-cm-long string fixed at both ends, vibrating in four segments at a frequency of 120Hz. The wavelength is calculated using the formula Lambda = 2L/n, resulting in a wavelength of 60cm. The discussion confirms that this calculation is correct. The fundamental frequency can be derived from the relationship between frequency and wavelength, but it is not explicitly calculated in the thread. The conversation centers on verifying the accuracy of the wavelength calculation.

Homework Statement


A standing wave is established in a 120-cm-long string fixed at both
ends. The string vibrates in four segments when driven at 120Hz.
(a) Determine the wavelength
(b) What is the fundamental frequency of the string?

Homework Equations


(a) Lambda = 2L/n


The Attempt at a Solution


(a) Lambda = 2(120cm) / 4 = 60cm

Is this right? doesn't seem to be

That looks right to me.
 
Thread 'Collision of a bullet on a rod-string system: query'

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 hanged mass'

Thread 'A cylinder connected to a hanged 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...
