Homework Help: Very Simple vibrations problem

  1. Mar 29, 2010 #1
    1. The problem statement, all variables and given/known data

    For the hoisting mechanism shown, what is the static stiffness (N/m) at point A, in the vertical direction? Assume the beam and rope materials are linearly elastic.

    2. Relevant equations

    You can make progress by starting with the definition of stiffness, being the rate of change of applied force with respect to deflection in the direction of that force. i.e. k=dfx/dsx

    3. The attempt at a solution

    Is this as simple as drawing a free body diagram with one force being mg and the other being kl and then just rearanging to give k=mg/l??
