The sign conventions used to define the forces (components of 



tension) and motion of the top of the cable are shown in Figure 10. 



T and T are the horizontal and vertical components of the tension 

 x y 



in pounds and y is displacement in feet, of the form 



y = a sin wt (17) 



where 



a is motion amplitude in feet, 



t is time in seconds, and 



u is frequency in radians per second.
