Question 986751: n object, that remains at rest, is acted upon by three forces F1, F2 and F3. The component forms of F1 and F2 are given by
F1 = ai + bj and F2 = ci + dj
where a = -198, b = 2, c = 71 and d = -40. If the component form of F3 is of the form F3 = xi + yj
then what is the value of x?

Sum of the forces in the x and y directions must equal zero since the body is at rest.
1.a%2Bc%2Bx=0
2.b%2Bd%2By=0
Substituting into eq. 1,
-198%2B71%2Bx=0
x=127
