Tension help

  1. Jan 28, 2008 #1
    this is probably really easy but i can't get it

    a 12kg mass is hanging from a clothes line. the line on the left forms an angle of 15 degrees and the angle of the line on the right forms a 25 degree angle. i have to solve for the tension on both sides of the clothesline

    i drew a free body diagram and two diagrams showing the components of tension but i still can't solve it this is what i came up with so far

    T1sin15 + T2Sin25 = 117.6N

    T1cos15 = T2cos15

    Yes, that looks almost right, but you meant T2cos25 in that last equation, I think. Now it's just algebra....plug in the numeric sin and cos values, and you have 2 equations and 2 unknowns, you should be able to solve for T1 and T2 using the algebraic method of your choice.
