Las fuerzas ejercidas por los fluidos en movimiento conducen al diseño de bombas, turbinas, aviones, cohetes, hélices, barcos, etc., por lo cual, la ecuación fundamental de la energía no es suficiente para resolver todos los problemas que se presentan y por lo tanto se necesita el auxilio del principio de la cantidad de movimiento.
Un collarín de 3 kg puede deslizarse sin fricción sobre una varilla vertical y descansa en equilibrio sobre un resorte. Se empuja hacia abajo, comprimiendo el resorte 150 mm y se suelta. Si se sabe que la constante del resorte es k=2,6 kN⁄m, determine:
La atura máxima h que alcanza el collarín sobre su posición de equilibrio.
La rapidez máxima del collarín.

I. AMORTIGUAMIENTO EN ESTRUCTURAS
Los amortiguamientos son generalmente valores numéricos para las relaciones de amortiguamiento modal y suficiente para análisis lineal.
Por lo tanto, determinar los coeficientes de la matriz de amortiguamiento; es necesario para armar la ecuación de equilibrio dinámico y realizar el análisis lineal.
El amortiguamiento o (fricción interna) es una de las propiedades más sensibles de materiales y estructuras, tanto a nivel macro como microscópico, siendo particularmente sensibles a la presencia de grietas y microgrietas. Es el fenómeno por el cual se disipa energía mecánica en un sistema (principalmente para la generación de calor y/o energía). La amortiguación determina la amplitud de la vibración en la resonancia y el tiempo de persistencia de la vibración después que culmina la excitación.

What price will pi network be listed on exchangesDOT TECH
The rate at which pi will be listed is practically unknown. But due to speculations surrounding it the predicted rate is tends to be from 30$ — 50$.
So if you are interested in selling your pi network coins at a high rate tho. Or you can't wait till the mainnet launch in 2026. You can easily trade your pi coins with a merchant.
A merchant is someone who buys pi coins from miners and resell them to Investors looking forward to hold massive quantities till mainnet launch.
I will leave the telegram contact of my personal pi vendor to trade with.

how to sell pi coins in South Korea profitably.DOT TECH
Yes. You can sell your pi network coins in South Korea or any other country, by finding a verified pi merchant
What is a verified pi merchant?
Since pi network is not launched yet on any exchange, the only way you can sell pi coins is by selling to a verified pi merchant, and this is because pi network is not launched yet on any exchange and no pre-sale or ico offerings Is done on pi.
Since there is no pre-sale, the only way exchanges can get pi is by buying from miners. So a pi merchant facilitates these transactions by acting as a bridge for both transactions.
How can i find a pi vendor/merchant?
Well for those who haven't traded with a pi merchant or who don't already have one. I will leave the telegram id of my personal pi merchant who i trade pi with.

how can I sell pi coins after successfully completing KYCDOT TECH
Pi coins is not launched yet in any exchange 💱 this means it's not swappable, the current pi displaying on coin market cap is the iou version of pi. And you can learn all about that on my previous post.
RIGHT NOW THE ONLY WAY you can sell pi coins is through verified pi merchants. A pi merchant is someone who buys pi coins and resell them to exchanges and crypto whales. Looking forward to hold massive quantities of pi coins before the mainnet launch.
This is because pi network is not doing any pre-sale or ico offerings, the only way to get my coins is from buying from miners. So a merchant facilitates the transactions between the miners and these exchanges holding pi.
I and my friends has sold more than 6000 pi coins successfully with this method. I will be happy to share the contact of my personal pi merchant. The one i trade with, if you have your own merchant you can trade with them. For those who are new.

I wouldn't advise you selling all percentage of the pi coins. Leave at least a before so its a win win during open mainnet. Have a nice day pioneers ♥️

how to sell pi coins effectively (from 50 - 100k pi)DOT TECH
Anywhere in the world, including Africa, America, and Europe, you can sell Pi Network Coins online and receive cash through online payment options.
Pi has not yet been launched on any exchange because we are currently using the confined Mainnet. The planned launch date for Pi is June 28, 2026.
Reselling to investors who want to hold until the mainnet launch in 2026 is currently the sole way to sell.
Consequently, right now. All you need to do is select the right pi network provider.
Who is a pi merchant?
An individual who buys coins from miners on the pi network and resells them to investors hoping to hang onto them until the mainnet is launched is known as a pi merchant.
