    Strings Tension
Click For Summary
To determine if all strings have the same tension, perform a moment balance around each pulley. The discussion emphasizes the importance of understanding moment balances in rigid bodies. It suggests that the question appears to be a homework query and recommends posting it in the appropriate homework section for better assistance. The conversation indicates a need for foundational knowledge in physics to tackle such problems. The thread concludes with a closure, indicating that further discussion is not encouraged.

Can you please tell me how to do that?

Have you not yet learned about how to do balances of moments on rigid bodies?
 
This looks very much like a homework question? If so you should really post it in the homework section where you will find a template.

Definitely looks like homework that should be re-posted in Introductory Physics Homework. Thread closed.
 
For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
