Solving String Tension for Weighted Rings

Click For Summary
SUMMARY

The discussion focuses on solving the tension in a light inextensible string of length 5a, secured horizontally with its ends 2a apart, while a small smooth ring with weight w is attached. The first part requires determining the tension in the string when the ring is stationary. The second part introduces a horizontal force of magnitude w applied to the ring, necessitating a reevaluation of the tension in the string under equilibrium conditions. Participants emphasize the importance of using force vectors and equilibrium equations to solve the problem effectively.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Knowledge of vector resolution in physics

Homework Statement



2.(i) A light inextensible string of length 5a is secured with its ends a horizontal distance 2a apart. A small smooth ring is free slide on the string and a weight w is attached to the ring. Determine the tension in the string.

(ii)A horizontal force of magnitude w is now applied to the ring. The system adjustes to become in equilibrium onc more. Determine he tension in the string.



2. The attempt at a solution
Ive tried this a few times, but it seems to get way too complicated. Any help would be appreciated!

Maybe you could draw a diagram of what this ring would look like at equilibrium. Since nothing would be in motion wouldn't it simply be a matter of looking at the force vectors that would hold the ring in position?

Similarly for part 2. Just add in your extra force vector to the drawing and write the equations for X and Y forces yes?
