1. The problem statement, all variables and given/known data The tower is 70 m tall. If the tension in cable BC is 2 kN, and you want to adjust the tensions in cable BD and BE so that the couple exerted on the tower by the fixed support at A is zero. A) Determine the tensions in cable BD and BE by applying the sum of the moments about point A . The Coordinates in meters B(0,70,0) A(0,0,0) C(-50,0,0) D(20,0,50) E(40,0,-40) 2. Relevant equations M=Fd 3. The attempt at a solution Well I know that I have to solve by taking the sum of the moments about A. That means that the Moment about A of Tension BC + Moment about A of Tension BD + Moment about A of Tension BE = 0 and The moment about A of Tension BC is nothing more than the Fx of Tension BC about the distance from point A to B. So That means I find the angle that Tension BC makes to the tower get my Fx and times it by the tower distance. So now what do I need to do next. Looking for the next step.
