The piston in a petrol engine goes up and down 3000 times per minute. For this engine, calculate the frequency and period of the piston.
Part 1: Given data
No. of cycles of petrol engine per minute = 3000.
1 minute = 60 seconds.
Part 2: Formulas Required
Frequency is the number of cycles per unit time.
Time period: No. of seconds per oscillations or cycles.
Frequency and time period are inversely proportional to each other.
Frequency ( f ) = hertz.
Time period= seconds.
Part 3 : Calculations.
Frequency ( f ) = hertz.
f =
f = or .
Time period (t) = seconds .
t = .
Part 4: Conclusion
Hence, the frequency is 50 Hz and the time period is 0.02 seconds.
