Equilibrium in roof trusses

  1. Nov 7, 2003 #1
    Question on equilibrium in roof trusses...

    The diagram for this quesion is at http://www.drewtemp.com/helios/physics.gif [Broken]

    1. What i want to find is which members are in tension and compression (AB, BC, AC)?

    2. What is the force at AC?

    3. What force from the left (the wind) is required to make the truss pivot at C?

    Rember the weight of AC is taken as 0. Someone please show me how to arive at the answer....

    Attachment available....

    You should probably start by making a free body diagram.
