Chapter 4, Problem 30PE
(a) Find the magnitudes of the forces F1 and F2 that add to give the total force Ftot shown in Figure 4.35. This may be done either graphically or by using trigonometry. (b) Show graphically that the same total force is obtained independent of the order of addition of F1 and F2. (c) Find the direction and magnitude of some other pair of vectors that add to give Ftot. Draw these to scale on the same drawing used in part (b) or a similar picture.

Two forces given f1 = 100N at 0 degree and f2 = 50N at 90 degree. Now use the component method, express the two forces and their sum in terms of their components. What should the components of the third force be to cancel them out? Using the components and find the magnitude and direction of this third force vector.
need to determine the missing values. Then, you will test your answers using one of the force tables. All angles need to be in the range from 0° to 360°, where 0° points along the positive x-axis, 90° points along the positive y-axis, 180° points along the negative x-axis, and 270° points along the negative y-axis. For the vector -A, the negative of a vector is antiparallel to the vector itself.
