(A) What is the maximum tension possible in a 1.00-millimeter-diameter nylon tennis racket string? (B) If you want tighter strings, what do you do to prevent breakage: use thinner or thicker strings? Why? What causes strings to break when they are hit by the ball?

Complete Question

(A) What is the maximum tension possible in a 1.00- millimeter-diameter nylon tennis racket string?

(B) If you want tighter strings, what do you do to prevent breakage: use thinner or thicker strings? Why? What causes strings to break when they are hit by the ball?

The  tensile  strength of the nylon string is  

A

   T = 471.3 \  N

B

 To prevent breakage the thickness of the string is increased

  String breakage when the racket hit the ball is as a result of the string not being thick enough to withstand the increase in tension

Explanation:

From the question we are told that

     The  diameter is    

       The  tensile strength of the nylon string is

  Generally the radius is mathematically evaluated as

=>    

=>    

The cross sectional area is mathematically represented as

=>  

=>    

Generally the tensile strength of nylon is mathematically represented as

Where T is the tension on the maximum tension on the string

 So  

=>          

=>        

Form the equation above  we  see that

So if the tension is  increased to prevent breakage the thickness of the string is increased(i. e the cross-sectional  area )

String breakage when the racket hit the ball is as a result of the string not being thick enough to withstand the increase in tension
