QUESTION:

If the coordinate direction angles for \(F_3\) are \(\alapha_3 = 120^{\circ}\), \(\beta_3 = 60^{\circ}\) and \(\gamma_3 = 45^{\circ}\), determine the magnitude and coordinate direction angles of the resultant force acting on the eyebolt.

ANSWER:

Step 1 of 7

Note that force lies in the -plane, so we can divide it into - and -components.

Since force makes with the -axis angle of , we can calculate the -and - components of the force as:
