Problem Check: Equilibrium of Particles

AI Thread Summary
The discussion revolves around a problem involving a continuous cable and pulleys, where the goal is to determine the mass of each block given the spring stretch and initial conditions. The user expresses uncertainty about their solution, noting that the scenario leads to equal spring tensions and weights. They mention the possibility of arriving at correct answers through luck rather than a systematic approach. The conversation highlights the complexity of equilibrium in particle systems, particularly in special cases. The importance of verifying calculations in physics problems is emphasized.

Homework Statement


A continuous cable of total length 4 m is wrapped around the small pulleys at A, B, C, D. If each spring is stretched 300 mm, determine the mass m of each block. Neglect the weight of the pulleys and cords. The springs are unstretched when d=2 m.

The Attempt at a Solution



I just need someone to tell me if I've done this correctly. Thank you!

it stopped as a square! (very special case) where the spring tensions are equal the weights. looks right.
there will be lots of "accidentally correct" (or lucky guess, then check) answers to this one!

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...
