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.

What equivalent fractions do the number lines show?
maks197457 [2]
Hello there, I'm Steel42, and I am here to help you today.

Let's look at some key words:

Equivalent - somethings that is equal in amount, value, or function

Fractions - It represents a part of a whole

Now, our problem,

Q:How do you find equivalent fractions?
A: If you can multiply or divide the top and bottom numbers by the same number, there equal.

Lets see if any are equal:          
1 whole equals two 1/2            
1 whole equals three 1/3           
1 whole equals four 1/4             
1 whole equals five 1/5           
1 whole equals six 1/6              
1 whole equals seven 1/7         
1 whole equals eight 1/8

one 1/2 equals two 1/4
one 1/2 equals three 1/6
one 1/2 equals four 1/8
two 1/2 equals one whole

one 1/3 equals two 1/6
three 1/3 equals 1 whole

one 1/4 equals two 1/8
four 1/4 equals one whole
two 1/4 equals one whole

two 1/6 equals one 1/3
six 1/6 equals one whole
three 1/6 equals one 1/2
three 1/6 equals two 1/4
three 1/6 equals four 1/8

two 1/8 equals one 1/4
four 1/8 equals one 1/2
four 1/8 equals two 1/4
four 1/8 equals three 1/6
eight 1/8 equals one whole

Hope This helps you today : )
