SOLUTION: 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

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.
2.
Substituting into eq. 1,
