DISCUSSION THREAD

HINTS:

Part a) - Write down the position vector from A to B: r_AB. The unit vector from A to B is found by u_AB=r_AB/|r_AB|. From this, the force of cable AB acting on the mast is: F_AB = F_AB*u_AB.

Part b) -Worked out in a similar way, with AB to be replaced by AC.

Part c) - Refer to the lecture book for determining the direction angles and direction cosines directly from a unit vector that has been written in component form.

Please post questions here on the homework, and take time to answer questions posted by others. You can learn both ways.
