A sinusoidal force with a given amplitude is applied to an oscillator.To maintain the largest amplitude oscillation the frequency of the applied force should be:
A)half the natural frequency of the oscillator
B)the same as the natural frequency of the oscillator
C)twice the natural frequency of the oscillator
D)unrelated to the natural frequency of the oscillator
E)determined from the maximum speed desired

Question

Quizplus · Accepted Answer

The frequency of the applied force should be the same as the natural frequency of the oscillator in order to maintain the largest amplitude oscillation. This is known as resonance, where the natural frequency of the oscillator and the frequency of the applied force are in sync, resulting in maximum amplitude.
