COMPONENT ADDITION METHOD
Component Addition Method Summary
Determine the x- and y- axes of all original vectors.
Mathematically combine all x-axis components.
Mathematically combine all y-axis components.
The results are the components of the resultant vector.
Follow the sequence used in the first example. Remember that x at 180 is -x at 0 , and y at
270 is -y at 90 .
F = 30 + 50 +(-45) + 15 = 50 lbf
F = 10 + 50 + 30 + (-50) = 40 lbf
F = 50 lbf at 0 , 40 lbf at 90
