Given the vector F1 = 100 N,
Ѳ1 = 20o , and F2
= 200 N, Ѳ2 = 90o and
F3= 300 N, Ѳ3
=220o . Find the magnitude and direction of the
resultant F= F1 +
F2 + F3
using the following method:
Analytical: Use the component method.
(6pts.)
Graphical: Use the polygon method.
(6pts.)
Use a percent error calculation to determine how close the
graphical result are to the analytical method.
