Chegg Discuss why stress-strain behavior of material is critical than just the ultimate strength of the material. What propertie
DanielleElmas [232]

Answer:

Throughout the clarification section elsewhere here, the definition of the concern is mentioned.

Explanation:

  • The stress-strain curve provides designers with a long list of critical parameters that are needed for utility development. Including capacity, longevity, elasticity, apparent viscosity, tension electricity, resilience, as well as flexural strength, a load-pressure assignment gave us several mechanical households at a certain point of operation. It also assists in manufacturing.
  • During which the overarching force can inform us about the maximum energy either workload the substance will experience, which could also be inferred within the action of the stress-strain. The dynamic properties can be seen by pre maximum activity because it will be before even the maximum yield intensity as well as the posted maximum would display plastic behavior however after the peak becomes achieved, the natural frequencies continue to decline.

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.

An automobile tire with a volume of 0.8 m3 is inflated to a gage pressure of 200 kPa. Calculate the mass of air in the tire if t
saveliy_v [14]

Answer:

2.83 kg

Explanation:

Given:

Volume, V = 0.8 m³

gage pressure, P = 200 kPa

Absolute pressure = gage pressure + Atmospheric pressure

= 200 + 101 = 301 kPa = 301 × 10³ N/m²

Temperature, T = 23° C = 23 + 273 = 296 K

Now,

From the ideal gas equation

PV = mRT

Where,

m is the mass

R is the ideal gas constant = 287 J/Kg K. (for air)

thus,

301 × 10³ × 0.8 = m × 287 × 296

or

m = 2.83 kg

An operating gear box (transmission) has 350 hp at its input shaft while 250. hp are delivered to the output shaft. The gear box
True [87]

Answer:

Rate of Entropy =210.14 J/K-s

Explanation:

given data:

power delivered to input = 350 hp

power delivered to output = 250 hp

temperature of surface = 180°F

rate of entropy is given as

Rate\  of\ entropy  = \frac{Rate\ of \ heat\  released}{Temperature}

T = 180°F = 82°C = 355 K

Rate of heat = (350 - 250) hp = 100 hp = 74600 W

Rate of Entropy= \frac{74600}{355} = 210.14 J/K-s
