For instance if you have a block of weight 10 N, held up by a cable connected to four pulleys, is the tension 10 N in the cable no matter where you are at?

The tension is a force and I think you mean the magnitude of it. In introductory physics yes, the magnitude of the tension is the same along the cable.
(I don't know if it's true in say solid state physics).

What even happened to the forum rules that people posting on here should make some sort of attempt? before you help them? Why even try to help people trying to ridicule people like you, me, Deco, physicsquest etc etc by some sort of poxy question with no fundamentals!!! Last edited by Paul46; Sep 18th 2009 at 01:03 PM.

Hey Paul,
as far as I understand, moodylurker08 didn't ask us to solve a physics problem. Rather I see that he's doing a physics problem and he has a doubt : does the magnitude of the tension remains the same through the cable? He believed so but wasn't sure. I just cleared his doubt. There's no need to invoke the forum rules here.
By the way I don't think he wants to ridicule us, he's just curious and it's nice.
