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,
Magnitude of DC, Position vector of DE, Magnitude of DE, Force vector of the cable BA, Force vector of the cable DC,
Force vector of the cable DE, a) First we reduce the given force to a single couple at the origin. The force is the
