A 10-mm-diameter cable is strung between a series of poles that are 50 m apart. Determine the horizontal force this cable puts on each pole if the wind velocity is 34 m/s.

The value is  

Explanation:

From the question we are told that

   The diameter is  

    The distance between the poles is  L =  50 m

      The velocity of the wind is  

Generally the horizontal force the cable puts on each other is mathematically represented as

Here A is the area of the rope(i.e assuming the rope to be a cylinder ) which is mathematically represented as

=>  

=>  

Here is the coefficient of discharge of the rope and the value is  

          is the density of air with value  

 So

=>  

=>  

their crystal patterns have been disrupted by stress
