Expert Solution

Step 1

(5)

Consider the wing of a plane on which a turbine is mounted having an unbalanced mass m at a distance r from the center and rotating with some angular velocity ω. The wing can be assumed as a cantilever beam of a material having young’s modulus E. The diagram for the system is shown below.

The magnitude of the unbalanced force is

Now the vibration equation for the above system for a small displacement x can be written as,
