There is no stress in the longitudinal direction since the pipe has no open ends.

What is longitudinal stress?

The tension that results from subjecting a pipe to internal pressure is known as longitudinal stress. A pipe's longitudinal stress acts in the direction of the pipe's length because it is parallel to the longitudinal axis of the pipe's centerline axis.

Tensile stress and compressive stress are two further subtypes of longitudinal stress. Tensile tension is the term for a type of stress that causes a body to grow longer.

Open ended pipe -longitudinal stress:

As we know if there are open ends there won't be any longitudinal stress

Hence, we can conclude that open pipes have no longitudinal stress

Explanation:

mean is basically taking the sum of all numbers and then dividing the sum with the number of all given numbers..

here, the mean is 9, total numbers are 10.. so the sum will be 9 multiplied by 10, that is 90.

If the mean of 10 numbers is 9, then the sum (total) of these numbers will be​ 90. The correct option is D.

The mean is the average of a set of variables in mathematics and statistics. The mean can be calculated in a variety of ways, including the simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean. Mean is denoted by a small m.

To calculate mean: Arrange the data items in ascending order from least to greatest. If the number of points is odd, the median is the data point in the middle of the list. If the number of data points in the list is even, the median is the average of two middle data points.

Mean = total sum of the numbers/total numbers

9 = total sum of the numbers / 10

The sum of the terms = 9 x 10 = 90

90 = total sum of the numbers

Therefore, the correct option is D. 90

While a drawing set is used to label and organize drawings, a drawing area is an optional feature that allows you to completely separate drawings within a project.

Around the world, consultants and designers frequently create construction drawings using their own standards for drawing numbers, which can lead to some misunderstanding on the construction site. Simply because this is how it has been done for many years, many consulting and design offices continue to utilise their own proprietary systems for numbering drawings.

As a potential solution to the issue, nations and standardisation committees have each created their own drawing numbering structures and standards.

In the past ten years, numerous of these national standards have been developed, such the National CAD Standard for the United States, the National BIM Standard, the CAD standards for the United Kingdom, the CAD standards for the Eurocode, etc.

The values for the datatypes variable after the following statement executes are: ch = '2', x = 76

What is datatype?

Data types describe the kinds of values that a variable can store. They establish the kind of operations that can be carried out on the data, the amount of memory needed to hold the data, and the possible range of values. Integer, float, double, char and boolean are a few examples of common data types. A boolean datatype stores either true or false values, while a float or double data type stores floating point numbers, a char data type stores single characters, a string data type stores a series of characters, and an integer data type stores full integers. The type of data to be saved and the unique program requirements both influence the datatype to be used.

Answer:

a) the tension in the cord T is 1200 N

b)

reaction at C along x-axis Cy is 400 N

reaction at C along y-axis Cy is 1200 N

reaction at C along z-axis Cz is 0 N

reaction at D along X-axis Dx is 1600 N

reaction at D along y-axis Dy is -480 N

Explanation:

a)

to find the tension in the cord, we say;

∑ Mz = 0

720(200) - T(120) = 0

144000 - 120T = 0

T = 144000/120

T = 1200 N

the tension in the cord T is 1200 N

b)

the reactions at C and D. Assume that the bearing at D does not exert any axial thrust.

we make use of the moment law of equilibrium at point D about y-axis.

∑ MDy = 0

Cx(120) - T(40) = 0

we substitute value of T

Cx(120) - 1200(40) = 0

Cx 120 = 48000

Cx = 48000/120

Cx = 400 N

reaction at C along x-axis Cy is 400 N

​  

Next we also​ apply the moment law of equilibrium at point D about x-axis.

∑MD z = 0

-Cy(120) + 720(80 + 120) = 0

-Cy(120) = - 144000

Cy = -144000 / - 120

Cy = 1200 N

reaction at C along y-axis Cy is 1200 N

we also​ apply the force law of equilibrium along z direction

∑Fz = 0

Cz = 0 N

reaction at C along z-axis Cz is 0 N

we also​ apply the force law of equilibrium along x direction

∑Fx = 0

Cx + Dx + T = 0

Substitute 400N for Cx and 1200 N for Dx

so

400 + Dx + 1200 = 0

Dx = 1600 N

therefore reaction at D along X-axis Dx is 1600 N

we also​ apply the force law of equilibrium along y direction

∑ Fy = 0

Cy + Dy - 720 = 0

we substitute Cy = 1200 N

so

1200 + Dy - 720 = 0

Dy = - 480 N

therefore reaction at D along y-axis Dy is -480 N

Answer:

The resistance of the flow of charges in an electric circuit (electrical resistance) is analogous to the frictional effect between water flow through a pipe and the pipe's surface

Explanation:

In comparison to its similarity to the diameter of the pipe affects the flow of water and acts a a factor affecting resistance so are there factors affecting electrical resistance.

in an electrical circuit:

the total length of the wire is to the length of a pipe of water

the cross-sectional area of the wire is to the diameter of a pipe of water.

Thus, the cross sectional are affects the amount of electrical resistance. Wider wires have wider cross-sectional area and vice versa. Also, water will flow (i.e. current) through a wider pipe (i.e. large diameter) at a faster rate than a narrow pipe (i.e. small diameter). This is due to the lower amount of resistance offered by the wider pipe.

in the same manner, the wider the wire, the lesser the electrical resistance to the flow of elsctric charge and vice versa for thiner wires.

It implies to increase the head of the pump while decreasing the length of the pumping system pipe and to increase the flowrate of the centrifugal pump while lengthening the pipe.

Two criteria—TEXTURE and COMPOSITION—are used to categorize rocks. The sizes, shapes, and relationships between the many mineral grains and other components that make up a rock are what determine its texture. The process that created the rock controls these elements. Color, hardness, luster, crystal formations, density, and cleavage are characteristics that aid in the identification of minerals in rocks by geologists. Crystal structure at the atomic level principally determines crystal shape, cleavage, and hardness. The chemical makeup mostly determines color and density. The most prevalent physical characteristics are those related to crystal structure, color, hardness, cleavage, and specific gravity.

Explanation:

The dual problem of a linear programming problem can be found by flipping the inequality signs and re-assigning the objective function as a constraint.

Given the following linear programming problem min 4x1 - 3 x2 subject to 3x1 - x2 ≤ 6 5x1 - 4x2 ≥ 8 x1 - 6x2 =5 x1, x2 ≥ 0To find the dual of the problem, the following steps can be taken:

Step 1: Flip the problem The first step in finding the dual problem is to flip the inequality signs of the constraint of the original problem. The constraints of the original problem are as follows:3x1 - x2 ≤ 65x1 - 4x2 ≥ 8x1 - 6x2 = 5Flipping the inequality signs of the above equations results in the following:3x1 - x2 ≥ 65x1 - 4x2 ≤ 8x1 - 6x2 = 5

Step 2: Re-assign the objective The next step is to re-assign the objective function of the original problem as a constraint. That is, the coefficients of the original objective function are used as constraints in the dual problem. Thus, for the given problem,

we have:4x1 - 3x2 = x0Step 3: Formulate the dual problem The dual problem can now be formulated by using the re-assigned objective function and the flipped inequality signs of the original problem. The coefficients of the original problem form the new objective function of the dual problem, while the flipped inequalities form the constraints of the dual problem. Therefore, the dual problem of the given problem is: minimize 6y1 + 8y2 + 5y3, subject to:3y1 + 5y2 + y3 ≥ 4- y1 - 4y2 - 6y3 ≥ -3Where y1, y2 and y3 are the dual variables corresponding to the original constraints. Thus, the dual problem of the given problem has been found.
