Homework Statement
I was just websearching and came across this interesting demonstration.

Homework Equations
I wanted to define the normal forces N1 and N2 based on their position x(t) from the center of gravity of the bar. the website says Normal force= w(1/2 ± x(t)/L). I really want to find out how they came up with that equation to define weight distribution.
I really need your help.
Thanks
