Problem 49P
(II) (a) What is the maximum tension possible in a 1.00-mm-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?
Step-by-step solution
Step 1 of 2
(a)
d=1mm=0.001m2 the diameter of the nylon string
r=d/2=1/2=0.5mm=0,5x10-3m=5x10-4m the radius of the string
compressive strength of the nylon= 500x106N/m2
Fmax=? maximum possible tension that the string can stand.
Maximum force that the nylon string at that thickness can stand is 393N
