Question: Determine (express all vectors in Cartesian-vector form): 1. The unit vector: AD (in the direction toward point D from point A) 2. The angles

Determine (express all vectors in Cartesian-vector form): 1. The unit vector: AD (in the direction toward point D from point A) 2. The angles Ox, Oy, ez, which the unit vector AD makes from the positive x, y, z directions, respectively (in degrees). 3. Draw the FBD of point A. You may choose to use the existing diagram below, or you may choose to create your own completely new diagram (the latter choice is better practice). 4. Write the equations of equilibrium for Point A and solve to find the magnitudes TAB, TAC, and TAD (in Newtons) of the respective cable-tension vectors: TAB, TAC, and TAD. (In the equilibrium equations, be sure to include the given weight W=-800 Newtons.)
