2-5M Determine the magnitude ,sense ,and direction of the resultant of the three forces acting at the top of the pole in Figure 2-14M

34 CHAPTER 2 (a) 60° 50 k Figure 2-14 T₁ R Q Q, 50 k (b) parallelogram are By using the fact that the opposite sides of a of the parallelogram of Figure 2-2. The components P and Q form a equal, we see that a force triangle (Figure 2-15) may be formed instead head-to-tail arrangement by transposing the force P. The resultant R that closes the triangle does not follow this head-to-tail order. This same procedure may be used to determine graphically the resultant of more than two concurrent forces. The forces shown in Figure 2-16(a) may be taken in any order to form a head-to-tail pattern. The force needed to close the polygon is the resultant of the system. Reversing the head-to-tail sequence will give the resultant the proper sense Figure 2-17 shows how the rectangular components of the forces P, Q, and I will add to have the same net effect as the components of the re- sultant force R. Figure 2-17(d) shows two polygons (with coincident or overlapping lines) that could be formed by the rectangular components P 60° P 50 kN 5 KN 3 50 KN Figure 2-14M Figure 2-15 Force triangle. Figure 2-16 Forces with rectangular components.
