Vectors VECTORS: RESULTANTS AND COMPONENTS Rev. 0 Page 11 CP-02 Figure 11 Vector Components Figure 12 Component Vectors As in the previous example, if only the resultant is given, instead of component coordinates, one can determine the vector components as illustrated in Figure 11. First, plot t he resultant on rectangular coordinates and then project the vector coordinates to the axis. The length along the x-axis is F , and the x length along the y-axis is F . This y method is demonstrated in the following example. For the resultant vector shown in Figure 12, determine the component vectors given F = 50 lbf at 53 . R o First, project a perpendicular line from the head of F to the x-axis and R a similar line to the y-axis. Where the projected lines meet, the axes determine the magnitude size of the component vectors. In this example, the component vectors are 30 lbf at 0 (F ) and o x 40 lbf at 90 (F ). If F had not already been drawn, the first step would have been to draw the o y R vector.
