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 5 kN and 6 kN, respectively. Calculate the resultant moment of these two forces about the origin, O. Use the vector method of computing moments in this problem. 6 m 4 m 2.5 m TAB F 80 cm B 3.7 m 5 m 4 m 4 TCD D 30° i 5m
