Vector addition by the components method In 2-D Cartesian coordinates: , xxxx yyyy VABC Va Ab Bc C V aA bB cC V aA bB cC =±±± ⇔=±±± GG " "" " Example Three forces A = 400 N, B = 250 N, and C = 500 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 = ++ G G G G . (1) Express the total force vector F G 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
