Explanation:
Given parameters:
Frequency = 500Hz
Unknown:
a. Period of rotation
b. Time required to complete 7 rotation
Solution:
The period of rotation is the time taken to complete a turn.
P = [tex]\frac{t}{n}[/tex]
P is the period
t is the time
n is the number of turns
Period is the inverse of frequency;
P = [tex]\frac{1}{500}[/tex] = 0.002s
b.
Time required to complete 7 rotation;
P = [tex]\frac{t}{n}[/tex]
t = P x n
t is the time
P is the period
n is the number of rotations
t = 0.002 x 7 = 0.014s
