Investiga por que esta simple actividad puede ayudar a mejorar las condiciones ambientales que tu comunidad?

Creo que por simple actividad hablas de reciclar no?

Espero que sea de ayuda (:

Permite ahorrar energía de forma significativa. Es menos costoso reciclar un material que fabricarlo desde cero, como ocurre por ejemplo con el vidrio.

Reciclar ayuda a evitar la explotación de los recursos naturales. El reciclaje hace posible que los materiales originales puedan ser aprovechados con un nuevo uso, sin que sea necesario volver a usar recursos naturales para fabricarlos.

Se evitan los métodos de extracción de recursos naturales, que son invasivos y contaminantes. El reciclaje permite no sustraer nueva materia prima para fabricación y se puede simplemente reciclar la materia existente.

Se reduce la contaminación, proporcionando una atmósfera más limpia. Reciclando ayudamos a reducir el daño producido al medio ambiente.

Se conserva el medio ambiente ya que permite reducir la cantidad de desechos sólidos que llegan a los vertederos. Esto hace posible que los vertederos ocupen menos espacio e incluso puedan llegar a cerrarse, evitando el impacto negativo que causan sobre el medio ambiente.

Permite alargar la vida útil de los vertederos, ya que se llenan a un menor ritmo evitando que se abran más vertederos.

Si depositamos los desechos que generamos en el contenedor correspondiente para que sean reciclados se reducen los costes de recolección y clasificación de los residuos, ya que son las personas las que ayudan a realizar dicha labor.

En algunos centros de reciclaje ofrecen una compensación económica por llevar material reciclable, como latas y botellas de plástico, por lo que puedes obtener un pequeño ingreso extra reciclando.

Compute the fundamental natural frequency of the transverse vibration of a uniform beam of rectanqular cross section, with one e
marshall27 [118]

Answer:

The natural angular frequency of the rod is 53.56 rad/sec

Explanation:

Since the beam is free at one end and fixed at the other hence the beam is a cantilevered beam as shown in the attached figure

We know that when a unit force is placed at the end of a cantilever the displacement of the free end is given by

\Delta x=\frac{PL^3}{3EI}

Hence we can write

P=\frac{3EI\cdot \Delta x}{L^3}

Comparing with the standard spring equation F=kx we find the cantilever analogous to spring with k=\frac{3EI}{L^3}

Now the angular frequency of a spring is given by

\omega =\sqrt{\frac{k}{m}}

where

'm' is the mass of the load

Thus applying values we get

\omega _{beam}=\sqrt{\frac{\frac{3EI}{L^{3}}}{Area\times density}}

\omega _{beam}=\sqrt{\frac{\frac{3\times 20.5\times 10^{10}\times \frac{0.1\times 0.3^3}{12}}{5.9^{3}}}{0.3\times 0.1 \times 7830}}=53.56rad/sec
