Question: A flagpole is guyed by three cables. If the tensions in the cables have the same magnitude P , replace the forces exerted on the pole with an equivalent wrench and determine ( a ) the resultant force R , ( b ) the pitch of the wrench, ( c ) the point where the axis of the wrench intersects the xz plane. Fig. P3.140 Answer : Tension in each of the three cables is Position vector of BA, Magnitude of BA, Position vector of DC,
