Questions & Step-by-Step Solutions

In a forced oscillation, if the amplitude is maximum, what can be said about the relationship between the driving frequency and the natural frequency?
  • Step 1: Understand what forced oscillation means. It is when an external force causes an object to vibrate.
  • Step 2: Know what amplitude is. Amplitude is the maximum distance the object moves from its rest position.
  • Step 3: Learn about driving frequency. This is the frequency of the external force applied to the object.
  • Step 4: Understand natural frequency. This is the frequency at which the object naturally wants to vibrate when not influenced by external forces.
  • Step 5: Realize that when the driving frequency matches the natural frequency, the object vibrates with maximum amplitude.
  • Step 6: Conclude that maximum amplitude in forced oscillation occurs when the driving frequency equals the natural frequency.
  • Forced Oscillation – A type of oscillation where an external periodic force drives the system.
  • Natural Frequency – The frequency at which a system tends to oscillate in the absence of any driving force.
  • Resonance – The phenomenon that occurs when the driving frequency matches the natural frequency, resulting in maximum amplitude.
