Calculate the normal force

  1. Jun 22, 2016 #1
    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.
