1. The problem statement, all variables and given/known data
An $D$ meter long wooden stick with a mass of $M$ is placed on two chairs of neglegible lenght. The left is $L$ meters from the left end and the right is $X$ meters from the right end. Find the expression for the both Normal forces that act from the chairs.

2. Relevant equations

3. The attempt at a solution
I am guessing i should begin by noting that the lever that acts on the right, mainly the gravitational force times x is adding to the normal and the left is lowering it right?

Your attempt doesn't make sense, was there a diagram?

Anyway, this is a static equilibrium problem, so draw a complete free body diagram and then apply the equations of static equilibrium.
