Aerospace Structures • Structural Dynamics & Aeroelasticity • Single & Multi-DOF Vibration Systems
Resonance in a structural vibration system occurs when:
(A) Excitation frequency equals natural frequency of the structure
(B) Damping ratio exceeds 1.0
(C) Stiffness approaches infinity
(D) Mass approaches zero
Answer Key:
A
Step-by-Step Verified Solution
### Solution: Resonance occurs when the external excitation frequency coincides with an undamped natural frequency of the structure, maximizing response amplitude. Correct: A.
