Pole AB is supported at point A by a pin joint, and held at point B by two wires, BC and BD, as described in the drawing. At point B acts on the pole force F which equals 500 [N]. The force F acts on a horizontal plane parallel to Axy, and is slated to an axis parallel to the y axis, and an angle psi that equals 30 degrees.
Calculate:
A) Tension on the wires.
B) That reaction forces at pin joint A
