A tower is guyed by cables AB and AC. A worker ties a rope oflength 12 m to he tower at A and exerts a constant force of 160 Non the rope.
(a) Express the tension in each cable as a function oftheta knowing that the resultant of the tension in the cables andthe rope is directed downward.
(b) Plot the tension in each cableas a function of thete 0 < theta < 180 degrees, and determinefrom the graph the range of values of theta for which both cablesare taut.
