Finding tension force and and components of a uniform boom

  1. Jul 20, 2012 #1
    1. The problem statement, all variables and given/known data

    A 1200-N uniform boom at ∅=55° to the horizontal is supported by a cable at an angle θ=25.0° to the horizontal. The boom is pivoted at the bottom and an object of weight 2 000 N hangs from its top.
    Find (a) the tension in the support cable and (b) the horizontal and vertical components of the reaction force exerted by the pivot boom.

    2. Relevant equations

    [itex]\tau[/itex]=Fd
    ƩF[itex]_{}x[/itex]=0
    ƩF[itex]_{}y[/itex]=0

    3. The attempt at a solution

    What I did was start by drawing a diagram of the picture but I don't know how to draw in the force. Your help is appreciated!

    welcome to pf!

    hi kurispice! welcome to pf! :smile:
    "cable" (like "rope" or "string", but unlike "beam" "boom" etc) means that the force must be along the cable :wink:
