Challenge Problems
Push your limits with advanced challenges
A harmonic oscillator is driven at a frequency slightly above its natural frequency. Discuss how this affects the shape of the power vs. frequency graph and the average power absorbed.
💡 Hint: Consider how energy transfer changes when not at resonance.
If the phase lag is increased while keeping the applied force constant, determine the effects this has on average power absorption.
💡 Hint: Link changes in phase lag directly to the average power formula.
