Question
The h 120 ft tall communication tower is supported by three cables at A and a ball-and-socket support at
O. Cable AB is pre-tensioned with a magnitude TAB= 6 kips. The coordinates of points B, C, and D in the
ground (x, y) plane are:
B = (25, 30) ft
C=(-15, 25) ft
D = (10, −20) ft
Determine the magnitude of the tension in cables AC and AD and the normal force in tower AO.
