Homework Help: Homework problem need help!

  1. Mar 2, 2010 #1
    1. The problem statement, all variables and given/known data
    A package of mass m hangs from a short chord that is tied to the wall via cord 1 and to the ceiling via cord 2. Cord 1 is at an angle 40 degrees with the horizontal cord two is at an unknown angle.
    -For what value of the unknown angle of cord two is the tension minimized?
    -In terms of mg, what is the minimum tension in cord 2?


    2. Relevant equations



    3. The attempt at a solution
    mg= FT1 +FT2. I attempted to find the minimum tension first, but honestly I have no idea where to start

    First, draw a free-body diagram for every mass. Draw out all forces and write down Newton's second law for both the x and the y components.
