Challenge Problems
Push your limits with challenges.
Question 1
A mass-spring system is driven by an external force with an amplitude of 5 N. If the amplitude of oscillation is 2 m, calculate the average power if the phase lag is 30 degrees.
💡 Hint: Use cosine of the phase angle and plug into the average power formula.
Question 2
Describe the effects of increasing the driving frequency on power absorption when approaching the natural frequency.
💡 Hint: Consider what happens as you tune in a radio; the closer you get to the right frequency, the clearer the sound.
