About the product
A pendulum whose oscillation amplitude increases due to the force of the wind"... Can you believe it? Actually, it can be explained physically.
In this video,
✔️ Pendulum motion (harmonic oscillation, damped oscillation)
✔️ The mechanism of lift and counter-lift
✔️ and the problem of "self-excited oscillation
are explained in a simple and easy to understand way!
And most importantly, we use the real-life example of the 1940 Tacoma Narrows Bridge collapse,
where this physical phenomenon actually caused a bridge to collapse,
to demonstrate the profound depth of physics where 'a single sign can change the world'!
