Simple Body Diagram Problem

  1. Sep 17, 2008 #1
    1. The problem statement, all variables and given/known data
    A light spring balance is attached to two strings that passes over smooth pulleys. Loads of m1 and m2 are attached to the ends of the strings. If m1=m2=4.0kg, or m1=6kg m2=4kg, what is the reading of the spring balance.

    Ans: 40N and 48N

    I just need to know how do i do it. And a general theory behind it all. Sorry for this very simple question here. :frown:

    It's basically like this


    Cheers for the upcoming help.
