    Forces in a bridge-truss.

    I am hoping that I posted this in the correct section, if not can a mod/admin move it to the correct location.

    I am having trouble with this question and looking through my textbook there seems to be many very similar to it so I am hoping if someone can answer this one for me and show me how they got it, I can use that to figure the rest myself.


    Q: In the bridge-truss joint shown below, the forces acting on the members form a concurrent force system. Knowing that the joint is in equilibrium, determine the forces C and T.(Assume that the bottom of the truss is at a straight 180 degrees)

    You resolve the forces along x and y and set the sum of forces in each direction to zero. This will give you a pair of simultaneous equations in the two unknown forces which you can then solve.

    I agree on this. Can't have something to write for you provide it all.

    Credits for that CaptainBlack, I'm really slow in math but I'll try solving EastEnder905's problem by the help of your idea.
