a. A
b. B
c. C
d. D
e. E
2) If one of the oscillators is critically damped, which one is it?
a. A
b. B
c. C
d. D
e. E
3) Which of the oscillators has the weakest damping coefficient?
a. A
b. B
c. C
d. D
e. E
Thank you:)
We have a collection of 5 different mass/spring combinations that all have different properties. All of them have some damping and all have the same mass. The properties are summarized in the table below Name Natural FrequencyTime for oscillation Notes (cycles/second) to s to stop (seconds) 100 sec 300 sec 100 sec 10 sec 50 sec 2.0 5.0 20.0 Does not oscillate Does not oscillate. The mass and spring are the same as in DExplanation / Answer
1. B
As it's natural frequency is close to applied frequency.
2.D
No oscillations and 10 sec is less than case E 50 sec
3. B
As it is taking more time to come to rest.
