boyakko [2]

Answer:

El aluminio es un metal ligero con una densidad de 2.70 g/cm3, y por ello, aunque las aleaciones de aluminio tienen características mecánicas relativamente bajas comparadas con las del acero, su relación resistencia-peso es excelente. Es precisamente debido a esto que el aluminio se utiliza cuando el peso es un factor importante, como ocurre en las aplicaciones aeronáuticas y de automoción.

 

Tabla 13.8. Propiedades mecánicas y aplicaciones de algunas aleaciones comerciales de aluminio.

El aluminio también responde fácilmente a los diferentes mecanismos de endurecimiento, tal como se recoge en la tabla 13.8, donde se observa que el mecanismo más notable es el de endurecimiento por precipitación, donde se consigue una dureza hasta 30 veces superior a la del aluminio puro.

Por otra parte, el aluminio no suele presentar un límite de resistencia a la fatiga bien definido, de modo que la fractura puede suceder incluso a niveles muy bajos. Debido a su bajo punto de fusión, el aluminio no se comporta bien a temperaturas elevadas. Finalmente, las aleaciones de aluminio tienen escasa dureza, lo que origina poca resistencia al desgaste abrasivo en ocasiones.

On a map, Sacramento is 8 cm from San Francisco. This represents an actual distance of 91 miles. On the same map, Sacramento is
Marat540 [252]

Answer:

Sacramento is 8cm from San Francisco.

8cm in map = 91 miles

91/8 = 11.375

1cm in map = 11.375 miles

Sacramento is 7 cm away from Modesto.

7 · 11.375 = 79.625

The actual distance is 79.625 miles

Hey guys I don’t understand this one so can y’all please help me? :))))
aksik [14]

Answer:

11) c = 16.1

12) c = 11.4

Step-by-step explanation:

11)

a² + b² = c²

8² + 14² = c²

64 + 196 = c²

c² = 260

\sqrt{c^2} =\sqrt{260}

c = 16.1

12)

a² + b² = c²

7² + 9² = c²

49 + 81 = c²

c² = 130

\sqrt{c^2} =\sqrt{130}

c = 11.4

Find the value of the trig functions indicated
Naddik [55]

Answer:

D. ⅘

Step-by-step explanation:

According to the acronym for trig ratio, SOHCAHTOA, we know that:

sin (\theta) = \frac{opposite}{hypotenuse}

In the triangle given,

Opposite = √(20² - 12²) = √256 = 16

Hypotenuse = 20

Thus:

sin (\theta) = \frac{16}{20}

Simplify

sin (\theta) = \frac{4}{5}
