Which of the following represents the magnitude of each of the two component forces of the resultant, FR, in Figure 1-11?
a. F1 = 86.6 N, F2 = 50 N
b. F1 = 50 N, F2 = 60 N
c. F1 = 10 N, F2 = 90 N
d. F1 = 20.6 N, F2 = 79.4 N
ANS: A
Sin 60 = 0.866 multiplied by the force of 100 N = 86.6 N, and Cos 60 = 0.05 multiplied by the
force of 100 N = 50 N.
