Calculate the density of the material for a vibrating string

AI Thread Summary
The discussion centers on calculating the density of a material for a vibrating string. The user has attempted to solve the problem and is seeking validation for their answer. They note that mass per unit length (mu) is derived from the density multiplied by the cross-sectional area of the wire. Responses confirm that their reasoning appears sound. Overall, the calculations and understanding of the relationship between mass, density, and cross-sectional area are affirmed.

I have given this a go and was wondering if my answer seems reasonable.

I had worked out that the mass per unit length (mu) is also the density * cross sectional area of wire

It looks reasonable.

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'
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...
