Homework Help: Need help with tension triangular problem

  1. Apr 29, 2010 #1
    1. The problem statement, all variables and given/known data

    Need help with problem #4 and #6

    2. Relevant equations
    don't know where to start


    3. The attempt at a solution

    attempt at number 4, I used T1 T2 T3 as tension for each side, since the weight is the force downward the two side that connect to the weight so each side should get half, 274 N and using tangent. I got 548/tan(60) and got 316.387N is this right?

    number 6 I understand the CG of the block must get past the rotational point at the bottom right corner
