Homework Help: Cable Tension question

  1. Oct 2, 2011 #1
    1. The problem statement, all variables and given/known data
    A system of cables is used to support a crate of mass m = 49 kg as shown in the figure below (θ = 57°). Find the tensions in all three cables.

    2. Relevant equations

    T2=mg

    T3sinθ=T2

    T1=T3cosθ


    3. The attempt at a solution

    So I calculated everything to be:

    T1 = 300.06N
    T2 = 480.20N
    T3 = 566.24N

    I believe my answer is correct, however, everytime I input T1 into the online assignment, the answer is wrong. I am wondering if anyone can confirm my answers.

    Thanks

    T2 looks good, but T3 is a bit off and T1 even more so. Redo your calculation of T3 and T1.
