Question Solved1 Answer Practice Exercise 2.3 only. Thankyou Sample Problem 2.3 N W A particle is being acted upon by the following forces: F, = 4.0 N, east; F2 = 6.0 N, northeast; and F3 = 8.0 N, south. R₂ = F + F2 Find the resultant using the parallelogram method. You may add the E forces according to the grouping (F +F_)+F, . Rx = (F. + Fz) + F Solution: As shown in the figure, R, =F+F, while R2 =R, +F;. The resultant vector in the figure has nine scale units corresponding to F-scale: HIN 9 N. Using a protractor, the angle that the resultant makes with the S horizontal axis is 25°. Thus, the resultant is 9 N, 25° south of east. Chapter 2 Working with Directions 33 Practice Exercise 2.3 scale: tinct Using the same forces in Sample Problem 2.3, find F, +(F, +F). Compare your answer with the resultant obtained in Sample Problem 2.3. Polygon Method The polygon method is otherwise known as the tip-to-tail method. This method is more convenient than the parallelogram method when more than two vectors are to be added graphically. The following are the steps to be followed using the polygon method.
