The discussion revolves around determining the maximum weight that can be supported by five ropes, each with a capacity of 1500N. Participants are trying to understand the relationships between the tensions in the ropes, specifically how they relate to the pulleys involved. Clarification is provided on how the ropes interact with the pulleys, indicating that one rope supports the weight of the pulleys while another connects to the ceiling. The key focus is on establishing these relationships to solve the problem effectively. Understanding the pulley system's configuration is essential for calculating the maximum weight without breaking any ropes.

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:
