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. A 2.5 m 4 m TAB | F 80 cm 3.7 m 4 m TCD D 5 m 5m 30* E
