Homework Help: Finding tension and reaction force for a boom

  1. Jul 7, 2010 #1
    1. The problem statement, all variables and given/known data
    A 1100 N uniform boom is supported by a cable perpendicular to the boom, as in the figure below. The boom is hinged at the bottom, and a 2000 N weight hangs from its top.


    (a) Find the tension in the supporting cable.
    (b) Find the components of the reaction force exerted on the boom by the hinge.

    3. The attempt at a solution
    I can't find any examples in my book that look anything like this. Please help me to get started.

    They said the tension is perpendicular to the boom. The weight acts downwards.

    So what is the torque produced by the weight and the weight of the boom?
