Tension & Torque, Static Equilibrium

AI Thread Summary
In the discussion on tension, torque, and static equilibrium, the focus is on understanding how to analyze a system in equilibrium where the net forces and torques sum to zero. The initial thought is that since the system is not moving, the forces must balance out. The concept of treating the point where the net is exerting force as a point of rotation is introduced, but clarity is sought on which point to choose to eliminate the ground's force from the moment calculations. The key challenge is identifying a suitable pivot point for calculating moments without the influence of the ground force. This highlights the importance of selecting the correct point of rotation in static equilibrium problems.

The Attempt at a Solution



I'm not even really sure where to start with this. My first thought was that it's not moving, so presumably the forces sum to 0. I also thought of treating the point where the net is exerting force as a point of rotation, but that doesn't make much sense.

There's an unknown force you don't care about: the force of the ground on the pole. So you want to take moments about a point for which that force will have no moment. What point is that?

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...
