Homework Help: One problem with 3d x,y,z resultant questions

  1. Sep 24, 2009 #1
    So this first question

    http://tinypic.com/view.php?pic=2qls4s4&s=4

    I figured out F1 X,Y,Z but for F2 I cannot seem to figure it out at all, it seems impossible. I can only figure out the Y axis but not the X and Z, any ideas?

    Hi hisoko! :smile:

    Hint: call the unit vector in the F2 direction (a,b,c).

    Then you know that the angle between (a,b,c) and (0,0,1), and the angle between (a,b,c) and (0,1,0), are both 60º. :wink:
