Poster warned about not providing an attempt at a solution

Homework Statement: Two equal masses are glued to a massless hoop of radius R that is free to rotate about its center in a vertical plane. The angle between the masses is 2*theta. Find the frequency of small oscillations.

I dont get that if two masses, so where do we take the postion vector from? From the centre?

Relevant Equations: d/dt(dL/dtetha)=dL/dtetga

I couldn't even get the position vector. Help!

Hello Shahbakht, :welcome:

Can you do it for ##\theta = 0## ? We need some effort from you before we are allowed to assist -- see guidelines

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 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
