14 Section 2.5 Three-dimensional or Cartesian Vectors Resultant Force s

 

Question 1 – Determine the resultant force and direction angles

If FB = 600 N and FC = 800 N determine the resultant force and the direction angles of the resultant force acting on the flag pole.   Hint – resolve the two vectors into Cartesian or i j k vectors first.  You will need to find the unit vectors u AB and u AC.
