Homework Help: Cantilever physics problem

  1. Apr 19, 2010 #1
    1. The problem statement, all variables and given/known data
    A 3 m long cantilever with a mass of 250 kg is
    attached to a wall and also held in place by a steel cable
    that is attached to the far end of the cantilever at an angle
    of 30° with respect to the cantilever as shown in the figure
    at right. A 5 kg mass also hangs from the far end of the
    cantilever. Solve for the horizontal and vertical components of this force and use them to determine the magnitude of the force acting on the cantilever.

    2. Relevant equations
    I= (1/12)M(L^2)
    t=r X F

    I just have no idea where to even begin.
