Solving a beam and a torsion spring

  1. Apr 11, 2009 #1
    1. The problem statement, all variables and given/known data
    let there be a beam connected to a wall at one end (left).
    in the other end there is a cylinder attached to the beam with an inertia moment of I0
    the cylinder is then connected to a torsion spring which is connected to a right wall
    the beam (cantilever) has a inertia moment - I ,young modulus - E and the length is L.

    2. Relevant equations
    what are the exact boundary conditions of the problem? (I believe there are 4
    2 of the left ones are trivial)

    3. The attempt at a solution
    I thought of simply saying the torsion moment in one end has to be: tau=k*theta
    where tau is the torque and theta the angle of torsion (k is the spring constant), then i can find a connection between the height of the beam and angle of torsion
    (although not a linear one)
    but there must be another boundary condition...
