Vector addition by the components method In 2-D Cartesian coordinates: , xxxxyyyyVABCVaAbBcCVaAbBcCVaAbBcC=±±±⇔=±±±⇔GG""""Example Three forces A= 400 N, B= 250 N, and C= 500 Nare exerted on the pinned connector through tie rods as shown. The total force on the pin can then be obtained as FABC=++GGGG. (1) Express the total force vector FGin vector notations by using unit vectors . ˆˆand 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
