5. The figure below shows a pole OF, with two arms parallel to the ground, extending toward points A and C, respectively. The pole is supported by two cables, AB, and CD. The magnitudes of the tension forces TAB and TCD are 3.4 kN and 5.6 kN, respectively. Use the vector method of computing moments in this problem. (Hint: you can use your solutions t Homework 2, Question 2 to help simplify this problem.) a. Calculate the resultant moment of these two forces about the origin. b. Find the component of the resultant moment perpendicular to the pole OF. E 1.2 m TAB 60 cm 20 cm 23 1.2 m 70 cm TCD D 80 cm 1.5 m 28 E
