Calculating Density of Immersed Weight using Vibrations and Fluid Statics

AI Thread Summary
The discussion focuses on calculating the density of a weight based on its vibrational frequencies in air and water. The fundamental frequency of the wire with the weight is 392 Hz in air and drops to 343 Hz when the weight is immersed in water. This change in frequency is linked to the weight's buoyancy in the fluid, which affects its effective weight. Participants are prompted to consider how immersion in a liquid alters the weight of an object and its implications for density calculations. The conversation emphasizes the relationship between vibrations, fluid statics, and density determination.

Vibrations and Fluid Statics

One end of a horizonatal wire is fixed, while the other passes over a smooth pulley and has a heavy weight attached to it. The frequency of the fundamental note emitted when the wire is plucked is 392 Hz. When the weight is completely immersed in water, the new fundamental frequency is 343 Hz. Calculate the density of the weight.

WHat have you done so far? Do you know how the weight of an object changes when it is immersed in a liquid?
 
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...
