Resolution Vectors Question?

  1. Oct 7, 2009 #1
    1. The problem statement, all variables and given/known data
    I've got a diagram but here's the question.
    Two tugs A and B pull a ship along the direction XO.
    Tug A pulls the ship with a force of 30kN at an angle of 15°.
    Tug B pulls the ship with a force of 18kN at an angle of [theta]

    Find the angle [theta]


    2. Relevant equations



    3. The attempt at a solution
    I've tried creating a ratio to find the value [theta].
    30/15=18/x
    x=9°

    But I don't think that's right as it doesn't seem logical.

    Any suggestions ? :)

    Since the ship is moving along XO direction due to forces, their y components must cancel each other. Find the y-component of 30kN and 18 kN and equate them.

    Their y components as in horizontal components? And by equate them, what do you mean?

    In the given problem if XO represents the x-axis, then the vertical components must get canceled out.
