    1. The problem statement, all variables and given/known data

    In the figure a 6.00-m-long, uniform beam is hanging from a point to the right of its center. The beam weighs 138 and makes an angle of with the vertical. At the right-hand end of the beam a concrete block weighing is hung; an unknown weight hangs at the other end.
    If the system is in equilibrium, what is w ? You can ignore the thickness of the beam.
    2. Relevant equations

    F=ma

    3. The attempt at a solution

    i dont rly know where to start i just need a hint

    Does the beam weigh 138 kg? What is the angle that is made with the vertical?

    How much does this block weigh?
