Resolving A Vector Into Components

[rooney]

I need to resolve the 5kn force at point E into rectangular components. I have never done this for a vector that was at a 90 degree angle, and I don't know what to do. I tried one method using 45 degress for the components, but I did not get the correct answer when I used it in my calculations. Thanks.

Hello, rooney!

Well, it's not really at a 90 degree angle, is it?

      D           E
      *  *  *  *  * - - - - - + K
       * 60   60 * 90 *       :
        *       *         *   :
         *     *              *
          * 60*               L
           * *
            *
            F

Can you find angle KEL ?

Is it 30 degrees?

Is it 30 degrees?

Got to be - since DEK = 180 degrees
