Question: A rigid pole with cross-arms is subject to tensions in cables GF, AE (both unknown), and CD (which has a magnitude of 1.2 kN).

A rigid pole with cross-arms is subject to tensions in cables GF,

AE (both unknown), and CD (which has a magnitude of 1.2 kN).

A rigid pole with cross-arms is subject to tensions in cables GF, AE (both unknown), and CD (which has a magnitude of 1.2 kN). The connection to the ground at O supports forces in x, y, and z directions as well as a resisting moment in the z-direction (which means that the at O, Mo = Moz). a) Express the tension in each cable in vector (x, y, 2) format. b) Express the total Moment about O, simplifying it to terms in the x, y, z directions. c) Determine the tensions in cables GF and AE. 2m B m 1.5 m /C 15 m 3 m 3 m T=12 kN
