Question

Which of the following shows mechanical resonance?

• A. Balance wheel
• B. Pendulum
• C. Quartz crystal
• D. All of the above

Answer 1

Answer: (D)

All of the above

$Answer:-$ D

Mechanical resonance is the tendency of a mechanicalsystem to respond at greater amplitude when the frequency of its oscillations matches the system's natural frequency of vibration (its resonance frequency or resonant frequency) than it does at other frequencies.

examples: Most clockskeep time by mechanical resonance in abalance wheel,pendulum, or quartz crystal.
