Cables extend from A to B and from A to C as shown in fig 1. Cable AC exerts a 1000-Ib force F at A.

1. Express r _AB (the vector from A to B) in Cartesian representation (i?, j?, k? notation)
2. Express r _Bc (the vector from A to C) in Cartesian representation (i?, j?, k? notation)
3. What is the angle between the cables AB and AC?
4. Determine the vector component of F parallel to the cable AB.
