Flies flap their wings at frequencies much too high for pure muscle action. A hypothesis for how

Question:

Flies flap their wings at frequencies much too high for pure muscle action. A hypothesis for how they achieve these high frequencies is that the flapping of their wings is the driven oscillation of a mass-spring system. One way to test this is to trim a fly's wings. If the oscillation of the wings can be modeled as a mass-spring system, how would this change the frequency of the wingbeats?

Trimming a flys wings would change the characteristics of the flys massspring system and this change would likely affect the frequency of the wingbeats In a massspring system the frequency of oscillation depends on the mass of the object and the stiffness of the spring Heres how trimming the flys wings might affect the frequency of wingbeats Reduced Mass Trimming a flys wings would reduce the total mass of the flys wings which is an essential part of the massspring system The mass of the wings is connected to the inertia of the system Reducing mass means there is less inertia to overcome which can increase the frequency of oscillation Reduced Stiffness If the wing structure is damaged or trimmed it may also affect the stiffness of the springlike system The wings themselves contribute to the springiness of the system allowing them to bounce back and forth A reduction in stiffness could decrease the restoring force of the spring system which might lower the frequency of oscillation Altered Damping In natural systems like a flys wings there is also some damping which is the resistance to motion that gradually reduces the amplitude of oscillation Trimming the wings might alter the damping characteristics potentially affecting the frequency Behavioral Adaptation Flies may adapt their behavior to compensate for the changes in their wing structure They might change their wing motion patterns to maintain their desired flight capabilities which can also influence the frequency of wingbeats In summary trimming a flys wings would indeed affect the massspring systems characteristics that drive the wingbeats The outcome on the wingbeat ...View the full answer
