The specifications added by the object-oriented programming paradigm in the evolution of programming language paradigms towards software-oriented-computing (SOC) are: 1- Encapsulation, 2- Abstract data types, and 3- Synchronization.

The correct answer to the question is: A-1-2-3

In the evolution of programming language paradigms towards software-oriented-computing (SOC), the object-oriented programming paradigm adds several specifications. These specifications include: Encapsulation: This is a principle that enables bundling of data and methods together into a single unit called an object. Encapsulation helps in data hiding, where the internal details of an object are hidden from the outside world. It allows for better organization and modularity of code.

Abstract data types: Object-oriented programming allows for the creation of abstract data types (ADTs). An ADT is a data type that is defined by the behavior of its operations rather than its implementation. It provides a high-level interface for interacting with data, without exposing the underlying implementation details. This promotes code reusability and maintainability. Synchronization: Object-oriented programming languages provide mechanisms for synchronization, which ensure that multiple threads or processes can access shared data in a coordinated manner. Synchronization helps in preventing race conditions and maintaining data integrity in concurrent programming.

Answer: c. The creative middle way

Explanation:

As there is both an obligation to preserve jobs and to protect the environment, a creative middle way which involves compromise would be most effective.

The company involved should process and remove the worst pollutants alone while leaving others so that the process will not be so expensive that they have to close down.

They will do this till a better and more environmentally beneficial solution can be found at which point they can then clean up the previous pollutants with the hope that they have not irrecoverably damaged the environment.

The process of data processing by a computer involves several steps that take place in a specific order. The first step is inputting the data into the computer system. This can be done through various devices such as keyboards, scanners, or touchscreens. Once the data is entered into the computer, it is stored in the memory for further processing.

The second step is processing the data. This involves the use of the central processing unit (CPU) which performs mathematical and logical operations on the data. The CPU retrieves the instructions from the memory and executes them, which results in the desired output.

The third step is storing the output data. Once the CPU has processed the data, the result is stored in the memory. The output can be in various forms such as text, images, or sound.

The fourth step is displaying the output. The output is displayed on the screen, printer, or other output devices depending on the nature of the data and the desired format.

Finally, the last step is transmitting the output. If the output is required to be sent to another system or device, it is transmitted using various modes such as email, internet, or other networks.

Overall, these steps are followed in a sequential order to ensure efficient and accurate data processing by the computer. The speed and accuracy of the process depend on the hardware and software components of the computer system, as well as the complexity of the data being processed.

Large aircraft, turbojet-powered multiengine civil aircraft, and fractional ownership program aircraft are all subject to the operating regulations outlined in part 91, subpart F. Operations needed to comply with requirements under: are not subject to the rules of this component : Part 121, 125, 129, 135, and 137,

An air-breathing jet engine, the turbojet is frequently found in airplanes. It is made up of a gas turbine and a nozzle for propulsion. The gas turbine has a compressor, a combustion chamber, a turbine, and an air inlet with inlet guiding vanes (that drives the compressor). Fuel combustion in the combustion chamber heats the compressed air from the compressor before allowing it to expand via the turbine. The propelling nozzle expands the turbine exhaust, which is subsequently accelerated to a high speed to provide push. In the late 1930s, two engineers, Hans von Ohain in Germany and Frank Whittle in the United Kingdom, independently developed the idea into workable engines. Turbojets are only helpful in aviation because of their poor efficiency at low vehicle speeds. In rare instances, turbojet engines have been utilized to power vehicles other than airplanes, usually in an effort to break land speed records. When a vehicle is "turbine-powered," it most often means it has a turboshaft engine, a modified gas turbine engine that uses a second turbine to power a revolving output shaft. These are typical in hovercrafts and helos. On Concorde and the longer-range versions of the TU-144, which had to spend a lot of time travelling supersonically, turbojets were used.

Answer:

Thrust angle

Explanation:

The term that describes the way that the front wheels align themselves with the rear wheels when the car is moving in a straight line is called "thrust angle."

Thrust angle refers to the angle between the geometric centerline of the rear axle and the centerline of the vehicle. When a vehicle is properly aligned, the thrust angle should be parallel to the vehicle's centerline, which ensures that the front wheels are also aligned with the rear wheels and the vehicle moves in a straight line.

However, if the thrust angle is not properly aligned, the front wheels will not track straight ahead and the vehicle may pull to one side or the other. In these cases, a wheel alignment service may be necessary to adjust the thrust angle and ensure proper alignment.

A project team may choose to prepare a low-fidelity version of a website design using sticky notes for several reasons:

Sticky notes allow for quick and easy changes. Since they are easy to move around and modify, the team can iterate on the design quickly, making adjustments and improvements without investing significant time or resources. This promotes an iterative design process, enabling the team to refine and enhance the design rapidly.Collaboration and Communication: Sticky notes facilitate collaboration and communication among team members. They can be easily placed on a whiteboard or a wall, allowing everyone to visualize and discuss the design together. Team members can share their ideas, suggestions, and feedback by directly manipulating the sticky notes, fostering effective communication and collaboration within the team.Low Cost and Accessibility: Sticky notes are affordable and readily available, making them a cost-effective option for creating prototypes. Compared to digital design tools or high-fidelity prototypes, sticky notes are inexpensive and accessible to all team members, regardless of their technical expertise. This inclusivity encourages participation from different stakeholders and promotes a diverse range of perspectives during the design process.Focus on Conceptual Design: Low-fidelity designs with sticky notes primarily focus on the conceptual aspects of the website, such as layout, content organization, and user flow. By avoiding intricate details or visual aesthetics, the team can concentrate on the fundamental structure and functionality of the design. This allows for early validation and testing of design concepts before investing significant time and resources in higher-fidelity prototypes.Emphasis on User Experience: Sticky notes enable the team to simulate user interactions and test the usability of the design. By physically moving and rearranging the sticky notes, the team can simulate user flows and assess the user experience. This hands-on approach allows for early identification of potential usability issues, leading to design improvements and a better user experience.

Answer:

the elevation of the water surface over the obstruction is highest at 1.341 m

the maximum height of the obstruction h = 0.159 m

Explanation:

From the given information:

The diagrammatic expression for the water profile showing a rectangular channel  with 3 cm width carrying a 4 m3/s of water at a depth of 1.5 m with an obstruction 15 cm high is placed across the channel can be seen in the diagram attached below.

To calculate the elevation of the water surface over the obstruction, we need to  determine the following:

a. the velocity of the channel

b. the froude number at the upstream of the obstruction

c. the specific energy level

To start with the velocity V of the channel.

\(V_1 = \dfrac{Q}{A} \\ \\ V_1 = \dfrac{4 \ m^3/s}{(3 \times 1.5 ) m^2 } \\ \\ V_1 = \dfrac{4 \ m^3/s}{4.5 \ m^2}\)

\(V_1 = 0.88 \ m/sec\)

The froude number  at the upstream of the obstruction

\(F _{\zeta} = \dfrac{V_1}{\sqrt{gy__1}}\)

\(F _{\zeta} = \dfrac{0.88}{\sqrt{9.81 \times 1.5}}\)

\(F _{\zeta} = \dfrac{0.88}{\sqrt{14.715}}\)

\(F _{\zeta} = \dfrac{0.88}{3.836}\)

\(F _{\zeta} =0.229\)

\(F _{\zeta} \simeq0.3\)  which is less than the subcritical flow.

Similarly, the specific energy level for this process can be expressed as:

\(E_1 = \dfrac{V_1^2}{2g}+y_1\)

\(E_1 = \dfrac{0.88^2}{2 \times 9.81 }+1.5\)

\(E_1 = \dfrac{0.7744}{19.62 }+1.5\)

\(E_1 =0.039469+1.5\)

\(E_1 =1.539469\)

\(E_1 \simeq1.54 \ m\)

\(E_2 + \Delta z = E_1\)

\(E_2= E_1 - \Delta z\)

\(E_2= (1.54 - 0.15) \ m\)

\(E_2=1.39 \ m\)

Suppose ;

\(V_1 y_1 = V_2y_2\\ \\ Then; \ making \ V_2 \ the \ subject \ of \ the \formula\ we \ have: \\ \\ \\V_2 = \dfrac{V_1 y_1}{y_2} ---- (1)\)

From the energy equation:

\(E_2 + \Delta z = E_1\)

we can now substitute the above derived parameter and have :

\(E_2 + \Delta z=y_1 + \dfrac{V_1^2}{2g}\)

\(E_2 =y_1 + \dfrac{V_1^2}{2g} - \Delta z\)

\(E_2 =y_2 + \dfrac{V_2^2}{2g}\)

replace the value of \(V_2\) =\(\dfrac{V_1 y_1}{y_2}\)  in equation (1), we have:

\(E_2 =y_2 + \dfrac{( \dfrac{V_1y_1}{y_2})^2}{2g}\)

\(E_2 =y_2 + \dfrac{ {V_1^2y_1^2}}{2gy_2^2}\)

\(E_2 \times y_2^2 =y^3_2 + \dfrac{ {V_1^2y_1^2}}{2g}\)

\(y^3_2 - E_2y^2_2 + \dfrac{V_1^2y_1^2}{2g}=0\)

Replacing our values now; we have:

\(y^3_2 - 1.39 \times y^2_2 + \dfrac{0.88^2 \times 1.5^2}{2 \times 9.81}=0\)

\(y^3_2 - 1.39 \times y^2_2 + \dfrac{1.7424}{19.62}=0\)

\(y^3_2 - 1.39 \times y^2_2 + 0.0888=0\)

\(y^3_2 - 1.39 y^2_2 + 0.0888=0\)

\(y_2 = 1.341 \ m \\ \\ y_2 = - 0.232 \ m \\ \\ y_2 = 0.281 \ m\)

Therefore,the elevation of the water surface over the obstruction is highest at 1.341 m

What is the maximum height of the obstruction that will not cause a rise in the water surface upstream

In order to determine the maximum height , we need to first estimate the rise in water level surface of \(\Delta z\)

\(\Delta z\) = 1.5 - (1.341+ 0.15) m

\(\Delta z\) =  (1.5 - 1.491) m

\(\Delta z\) = 0.009 m

Finally, the maximum height of the obstruction h = (0.009 + 0.15 )m

the maximum height of the obstruction h = 0.159 m

Answer:

STANDARD DAVIATION OR SD

Explanation:

BECAUSE it is commonly in measuring of dispersion and it also the most roubst measure of variability

Answer:

See calculation below

Explanation:

Given:

W = 30 kN = 30x10³ N

d = 75 mm

p = 6 mm

D = 300 mm

μ = tan Φ = 0.2

1. Force required at the rim of handwheel

Let P₁ = Force required at the rim of handwheel

Inner diameter or core diameter of the screw = dc = do - p = 75 - 6 = 69 mm

Mean diameter of screw:    *d = \(\frac{do + dc}{2}\) = (75 + 69) / 2 = 72 mm

and

tan α = p / πd  =  6 / (π x 72)  =  0.0265

∴ Torque required to overcome friction at he threads is  T = P x d/2

T = W tan (α + Ф) d/2

T =  \(W(\frac{tan \alpha + tan \theta}{1 - tan \alpha + tan \theta } ) * \frac{d}{2}\)

T = 30x10³ * ((0.0265 + 0.2) / (1 - 0.0265 x 0.2)) x 72/2

T = 245,400 N-mm

We know that the torque required at the rim of handwheel (T)

245,400 = P1 x D/2 = P1 x (300/2) = 150 P1

P1 = 245,400 / 150

P1 = 1636 N

2. Maximum compressive stress in the screw

                         30x10³

Qc = W / Ac = -------------- = 8.02 N/mm²

                      π/4 * 69²

Qc = 8.02 MPa

Bearing pressure on the threads (we know that number of threads in contact with the nut)

n = height of nut / pitch of threads = 150 / 6 = 25 threads

thickness of threads, t = p/2 = 6/2 = 3 mm

bearing pressure on the threads = Pb = W / (π d t n)

Pb = 30 x 10³ / (π * 72 * 3 * 25)

Pb = 1.77 N/mm²

Max shear stress on the threads = τ = 16 T / (π dc³)

τ = (16 * 245,400) / ( π * 69³ )

τ = 3.8 M/mm²

*the mean dia of the screw (d) = d = do - p/2 = 75 - 6/2 = 72

∴max shear stress in the threads τmax = 1/2 * sqrt(8.02² + (4 * 3.8²))

τmax = 5.5 Mpa

3. efficiency of the straightener

To = W tan α x d/2 = 30x10³ * 0.0265 * 72/2 = 28,620 N-mm

∴Efficiency of the straightener is η =  To / T = 28,620 / 245,400

η = 0.116 or 11.6%

By assuming the coefficient of friction for the collar as 0.2. efficiency of straightner is 11.6%.

Wheels are circular frames or disks that are mounted on machines or vehicles and are designed to rotate around an axis.

Given:

W = 30 kN = 30x10³ N

d = 75 mm

p = 6 mm

D = 300 mm

μ = tan Φ = 0.2

1. Force required at the rim of handwheel :

Let P₁ = Force required at the rim of handwheel

Inner diameter or core diameter of the screw = dc = do - p = 75 - 6 = 69 mm

Mean diameter of screw:    *d =  = (75 + 69) / 2 = 72 mm and

tan α = p / πd  =  6 / (π x 72)  =  0.0265

Torque required to overcome friction at he threads is  T = P x d/2

T = W tan (α + Ф) d/2

T = 30x10³ * ((0.0265 + 0.2) / (1 - 0.0265 x 0.2)) x 72/2

T = 245,400 N-mm

We know that the torque required at the rim of handwheel (T)

245,400 = P1 x D/2 = P1 x (300/2) = 150 P1

P1 = 245,400 / 150

P1 = 1636 N

2. Maximum compressive stress in the screw :

30x10³

Qc = W / Ac = -------------- = 8.02 N/mm²

π/4 * 69²

Qc = 8.02 MPa

Bearing pressure on the threads (we know that number of threads in contact with the nut)

n = height of nut / pitch of threads = 150 / 6 = 25 threads

thickness of threads, t = p/2 = 6/2 = 3 mm

bearing pressure on the threads = Pb = W / (π d t n)

Pb = 30 x 10³ / (π * 72 * 3 * 25)

Pb = 1.77 N/mm²

Max shear stress on the threads = τ = 16 T / (π dc³)

τ = (16 * 245,400) / ( π * 69³ )

τ = 3.8 M/mm²

*the mean dia of the screw (d) = d = do - p/2 = 75 - 6/2 = 72

max shear stress in the threads τmax = 1/2 * sqrt(8.02² + (4 * 3.8²))

τmax = 5.5 Mpa

Therefore, efficiency of the straightener :

To = W tan α x d/2 = 30x10³ * 0.0265 * 72/2 = 28,620 N-mm

Efficiency of the straightener is η =  To / T = 28,620 / 245,400
