Extracted text: The guy wires AB and AC are attached to the top of the transmission tower. The tension in cable AB is 7.2 kN. Determine the required tension T in cable AC such that the net effect of the two cables is a downward force at point A. Determine the magnitude R of this downward force. Assume a = 30 m, b = 38 m, c = 26 m, and d = 33 m. B) Answers: T = i kN %3D R = i kN
