The film uses never-before-seen images and unheard interviews to bring Ella Fitzgerald to life and to tell the story of her music.

## What happens natural frequency?

Natural frequency, also known as eigenfrequency, is the frequency at which a system tends to oscillate in the absence of any driving or damping force. The motion pattern of a system oscillating at its natural frequency is called the normal mode (if all parts of the system move sinusoidally with that same frequency).

## What is a person’s natural frequency?

Human Vibration Parameter Comparison and Result Discussion. According to the existing research, the natural frequency of a human-standing body is about 7.5 Hz, and the frequency of a sitting posture in the cab is generally 4–6 Hz. The natural frequency of the main body parts is shown in Table 1.

## What is natural frequency and mode shape?

Natural Frequencies The natural frequencies of a structure are the frequencies at which the structure naturally tends to vibrate if it is subjected to a disturbance. Mode Shapes The deformed shape of the structure at a specific natural frequency of vibration is termed its normal mode of vibration.

## Why is resonance so dangerous?

Resonance may cause violent swaying motions in constructed structures, such as bridges and buildings. The London Millennium Footbridge (nicknamed the Wobbly Bridge) exhibited this problem. A faulty bridge can even be destroyed by its resonance (see Broughton Suspension Bridge and Angers Bridge).

## What are the disadvantages of resonance?

The main disadvantage of resonance (you don’t outline if this is acoustic, mechanical, electrical, etc., all have resonance issues) is that it can AMPLIFY via RESPONSE any input at/near the resonance, and the product can go whackadoodle and blow up. Structural resonances have brought down bridges!

## When should resonance be avoided?

There is an undesirable side effect of resonance. Resonance can cause a bridge, skyscrapers and towers to collapse. Even blades,piping and bearing can fail due to resonance. Therefore, resonance failures must be avoided.
