<u>Answer:</u> The numbers which can be expressed as a ratio of two integers where the denominator is not equal to zero

<u>Step-by-step explanation:</u>

Rational numbers are expressed in the form of $\frac{p}{q}$ where $q\neq 0$ . 'q' is the denominator in the above fraction.

The fractional form which is terminating or non-terminating recurring are considered as rational numbers.

The numbers 'p' and 'q' are the integers.

Integers are defined as number which is a proper number and not a fraction or decimal. All negative whole numbers are considered as integers.

<u>Some Examples of Rational numbers:</u> $\frac{5}{10}$ is a terminating fraction. $\frac{2}{3}$ is a non-terminating recurring fraction

Hence, the numbers which can be expressed as a ratio of two integers where the denominator is not equal to zero

aliya0001 [1]

Answer:

Step-by-step explanation:

This problem is a composition of function defined by C(V(r)), now we have the functions $V(r)= \pi r^{3}$ and $C(V)=3.2V$ , where the first depends on the radius, and the second dependes on the volume, that means, to find the number of ounce of coffe, we need to determine the volume of the cylinder, that's why we have to replace the volume function inside the ounces function,

$C(V(r))=3.2(\pi r^{3} )$

Therefore, the right answer is the last choice.

Show that p must be directed through centroids of cross sections if axial stress ? is not to vary over a cross section.

wolverine [178]

Assuming P (usually written in upper case) represents a force normal to a given cross section.

If a point load is applied to any point of the section, stress concentration will cause axial stress to vary.

The context of the question considers the uniformity of axial stress at a certain distance away from the point of application (thus stress concentration can be neglected).

If a force P is applied through the centroid, sections will be stressed uniformly. However, if the force P is applied at a distance "e" from the centroid, the equivalent load on the section equals an axial force and a moment Pe. The latter causes bending of the member, causing non-uniform stress.

If we assume A=(uniform) cross sectional area, and I=moment of inertia of the section, then stress varies with the distance y from the centroid equal to
stress=sigma=P/A + My/I
where P=axial force, M=moment = Pe.
Therefore when e>0, the stress varies across the section.

melamori03 [73]

Answer:

1.49216 x 10^11 m.

Step-by-step explanation:

That would be the following difference:

1.496 x 10^11 - 3.84 x 10^8

= 1.49216 x 10^11 m.
