GRAPHIC METHOD OF VECTOR ADDITION
Figure 19 Graphic Addition - Example 1
Determine the magnitude and direction of the resultant.
Measure the displacement and angle directly from the graph using a ruler
and a protractor.
Determine the components of the resultant by projection onto the x- and
What are the magnitude and direction of the resultant for the following: F = 3
units at 300 , F = 4 units at 60 , and F = 8 units at 180 ? The three vectors and
their resultant are shown in Figure 19.
F = 4 units at 150
Given X = 50 Ohms at 90 , R = 50 Ohms at 0 , and X = 50 Ohms at 270 , what
is the Resultant Z? (See Figure 20) Note: X is inductive reactance, X is
capacitive reactance and Z is impedance.
Z = 50 Ohms at 0o
