Cual es el esfuerzo que puede provocar un corte en el material
jolli1 [7]

Answer:

El esfuerzo cortante, de corte, de cizalla o de cortadura es el esfuerzo interno o resultante de las tensiones paralelas a la sección transversal de un prisma mecánico como por ejemplo una viga o un pilar. Se designa variadamente como T, V o Q.

Este tipo de solicitación formado por tensiones paralelas está directamente asociado a la tensión cortante. Para una pieza prismática se relaciona con la tensión cortante mediante la relación:

(1){\displaystyle Q_{y}=\int _{\Sigma }\tau _{xy}\ dydz,\qquad Q_{z}=\int _{\Sigma }\tau _{xz}\ dydz,\qquad Q={\sqrt {Q_{y}^{2}+Q_{z}^{2}}}}

Para una viga recta para la que sea válida la teoría de Euler-Bernoulli se tiene la siguiente relación entre las componentes del esfuerzo cortante y el momento flector:

A cast iron paperweight is in the shape of a half-sphere with a diameter of 8.2cm. The cast iron has a density of 7.3g/cm^3. Wha
Mnenie [13.5K]

Answer: C

1054 g

Explanation:

Given that the object is in the shape of semi sphere with diameter of 8.2cm. And density of 7.3g/cm^3.

From definition of density,

Density = mass/volume

Volume of a half - sphere = 2/3πr^3

Volume = 2/3 × 3.143 × 4.1^3

Volume = 144.35 cm^3

Let make mass the subject of formula

Mass = Density × volume

Mass = 7.3 × 144.35

Mass = 1053.74g

The mass of the paperweight, in grams is 1054
