Static Equilibrium of pedestals

  1. Oct 28, 2009 #1
    1. The problem statement, all variables and given/known data
    A diver of weight 730 N stands at the end of a diving board of length L = 5 m and negligible mass. The board is fixed to two pedestals separated by distance d = 1.5 m.

    What are the magnitude and direction of the force on the board from the left pedestal? (Include the sign. Take upward to be positive.)


    2. Relevant equations
    I think that it's this..

    sum of forces in the y direction = 0

    force of left pedestal = Fl
    force of right pedestal = Fr
    force of diver = mg = 730N



    3. The attempt at a solution

    -Fl + Fr - mg = 0
    3.5Fr(mg) - (0)mg = 5Fl(mg)

    is this on the right track?

    Looks good! You have 2 equations with 2 unknowns so you can find the answer.
