Vector addition by the components method In 2-D Cartesian coordinates: , xxxx yyyy V ABC VABC V aA bB cC V aA bB cC V aA bB cC =±±± ⇔=±±± ⇔= ± ± ± = ± ± ±   Example Three forces A = 200 N, B = 100 N, and C = 250 N are exerted on the pinned connector through tie rods as shown. The total force on the pin can then be obtained as F ABC =++ . (1) Express the total force vector F in vector notations by using unit vectors ˆˆ and ij . (2) Find the magnitude of the total force. (3) Also find the direction of the total force by its angle measured from the + x - direction
