Homework Answers
Part A)
In triangle , ACD
AD = Fu = component of the force along u-axis
AC = force F = 29 lb
using law of Sines
AC/Sin105 = AD/Sin45
F/Sin105 = Fu/Sin45
29/Sin105 = Fu/Sin45
Fu = 21.2 lb
Part B)
In triangle , ABC
AB = Fv = component of the force along v-axis
AC = force F = 29 lb
using law of Sines
AC/Sin105 = AB/Sin30
F/Sin105 = Fv/Sin30
29/Sin105 = Fv/Sin30
Fv = 15.0 lb
