SUMMARY

The discussion focuses on determining the maximum weight (W) that can be supported by five ropes, each with a tensile strength of 1500N. The user attempts to establish relationships between the tensions in the ropes, specifically noting that tension t1 equals 2t2. Clarification is provided regarding the configuration of the ropes and pulleys, with pulleys labeled A, B, C, and D, indicating how the ropes interact with these pulleys to support the weight.

PREREQUISITES
  • Understanding of basic physics concepts related to tension and forces.
  • Familiarity with pulley systems and their mechanics.
  • Knowledge of how to calculate forces in static equilibrium.
  • Ability to interpret diagrams related to physics problems.
NEXT STEPS
  • Study the principles of static equilibrium in physics.
  • Learn about the mechanics of pulley systems and their applications.
  • Explore tension calculations in multi-rope systems.
  • Review problem-solving techniques for physics homework involving forces and tensions.
USEFUL FOR

Students studying physics, particularly those tackling problems involving forces, tensions, and pulley systems. This discussion is also beneficial for educators seeking to clarify concepts related to static equilibrium and mechanical advantage.

Homework Statement



The five ropes in the picture can withstand 1500n each, how heavy can w be without breaking any?

Homework Equations





The Attempt at a Solution


First naming the tensions on the rope t1,t2,t3,t4,t5
and find the relationship between them, like t1 = 2t2
but i don't understand the picture...
can anyone help me to understand which rope is holding which rollers?
Thanks

Hi 385sk117! :smile:

If a rope ends in a blob in the middle of a pulley, then it's ending there, and supporting the wight of that pulley

So, calling the pulleys A B C and D from the left, the first string starts at the ceiling and goes round A and B and supports C, the other string starts at the weight W and goes round C and D and ends at the ceiling. :wink:
