Case Study Questions on Oscillations

Case Study Question 1

Bio-Inspired Rescue Drone Uses Oscillations to Survive Wind Turbulence

In 2026, a team of aerospace engineers developed a cutting-edge rescue drone inspired by the rhythmic wing-flapping of hummingbirds. Unlike conventional drones that use fixed propellers, this drone’s wings oscillate using an advanced system of simple harmonic motion (SHM) powered by micro-actuators and springs. The designers modeled the wing motion using differential equations of SHM to ensure maximum energy efficiency and flight stability.

During test flights in turbulent mountain air, engineers noticed something unusual. The wings’ oscillations began syncing with periodic wind gusts — a phenomenon similar to resonance. This led to large oscillation amplitudes, risking wing failure. To counter this, engineers integrated a damping feedback system that detects incoming gust patterns and dynamically alters the spring stiffness and mass distribution of the wings, thus shifting the drone’s natural frequency in real time.

This dynamic tuning approach, derived from the principles of SHM, damping, and forced oscillations, made the drone exceptionally stable in harsh weather — a major leap forward in search-and-rescue operations in remote, windy terrains.

Q1. What principle governs the natural up-and-down oscillation of the drone’s flexible wings?
(a) Projectile Motion
(b) Random Vibrations
(c) Simple Harmonic Motion
(d) Non-periodic Motion

Show Answer

Answer: (c) Simple Harmonic Motion
Explanation: The wings’ motion was periodic, oscillatory, and governed by a restoring force proportional to displacement — characteristics of SHM.

Q2. Why did the drone experience dangerously large wing oscillations in turbulent wind conditions?
(a) The wind froze the motors
(b) Damping became zero
(c) The wind’s periodic force matched the natural frequency
(d) The mass of the drone decreased

Show Answer

Answer: (c) The wind’s periodic force matched the natural frequency
Explanation: Resonance occurs when the frequency of external forces (wind gusts) matches the system’s natural frequency, causing a sharp increase in amplitude.

Q3. What is the purpose of the feedback damping system in the drone?
(a) To increase thrust
(b) To recharge the battery
(c) To dynamically control amplitude and frequency
(d) To change the shape of the wings

Show Answer

Answer: (c) To dynamically control amplitude and frequency
Explanation: The system adjusts mass and stiffness to shift the natural frequency and avoid resonance, reducing amplitude when gusts occur.

Q4. Which formula represents how the drone engineers adjusted natural frequency?
(a) f = v/λ
(b) f = 1/2π √(k/m)
(c) v = u + at
(d) f = ma

Show Answer

Answer: (b) f = 1/2π √(k/m)
Explanation: This formula gives the natural frequency of an SHM system based on spring constant (k) and mass (m). Engineers modified these to adapt the drone’s response.
