11.
Express the force F1 in Cartesian vector form.
12.
Determine the projection of the position vector r along the aa axis.
13.
What is the projection of the force F2 along the positive axis?
14.
Determine the magnitude and direction of the position vector r which points from point A to point B.
r = 12 ft, 
= 70.5°, 
= 48.2°, 
= 131.8°
= 70.5°, = 48.2°, = 131.8°r = 12 ft, = 109.5°, = 131.8°, = 48.2°
= 109.5°, = 131.8°, = 48.2°r = 12 ft, = 70.5°, = 48.2°, = 48.2°
= 70.5°, = 48.2°, = 48.2°r = 12 ft, = 109.5°, = 131.8°, = 131.8°
= 109.5°, = 131.8°, = 131.8°15.
Determine the magnitude of the x and y components of the 700-lb force.
