Answer:

Explanation:

ADT for an 2-D array:

struct array{

int arr[10];

}arrmain[10];

An application that stores an array with 1000 rows and 1000 columns, where less than 10,000 of the array values are non-zero. The two different implementations for such arrays that would be more space efficient than a standard two-dimensional array implementation requiring one million positions are :

1) struct array{

int *p;

}arr[1000];

2) struct array{

int *p;

}arr[1000];

**Complete Question **

For some metal alloy, a true stress of 345 MPa (50040 psi) produces a plastic true strain of 0.02. How much will a specimen of this material elongate when a true stress of 411 MPa (59610 psi) is applied if the original length is 470 mm (18.50 in.)?Assume a value of 0.22 for the strain-hardening exponent, n.

**Answer:**

The elongation is

**Explanation:**

In order to gain a good understanding of this solution let define some terms

**True Stress**

** **A true stress can be defined as the quotient obtained when instantaneous applied load is divided by instantaneous cross-sectional area of a material it can be denoted as .

**True Strain**

** **A true strain can be defined as the value obtained when the natural logarithm quotient of instantaneous gauge length divided by original gauge length of a material is being bend out of shape by a uni-axial force. it can be denoted as .

The mathematical relation between stress to strain on the plastic region of deformation is

Where K is a constant

n is known as the strain hardening exponent

This constant K can be obtained as follows

No substituting from the question we have

Making the subject from the equation above

From the definition we mentioned instantaneous length and this can be obtained mathematically as follows

Where

is the instantaneous length

is the original length

We can also obtain the elongated length mathematically as follows

**Answer:**

1) titration

2) titrand

3) equivalence point

4) titrant

5) Burette

6) Indicator

**Explanation:**

The process of adding a known volume a standard solution to another solution to react with it in order to determine the concentration of the unknown solution is known as titration.

The solution to which another solution of known concentration is added is called the titrand while the solution of known concentration is called the titrant.

A burette is a glassware used to slowly add a known volume of the titrant to the titrand. An indicator shows the point when the reaction is complete by a color change. This is the point when the required amount of one solution has been added to the second solution. It is also called the equivalence point.

The **diameter** of an 18 mm dine when expressed in micrometers is; 18000 micrometers

<h3>Conversion of Units</h3>

We are given the **diameter** of dime at 18 mm.

Now, from **conversion of units** between mm(millimeter) and micrometer, we know that;

1 millimeter = 1000 micrometer.

Thus, by proportion, 18 millimeter will be;

18 millimeters × 1000 micrometers/1 millimeter

>> 18000 micrometers

In **conclusion**, the diameter of the 18mm fine in micrometers is; 18000 micrometers
