Answer:

  4.2

Explanation:

The "allowance" is the difference between the maximum shaft size and the minimum hole size.

maximum shaft = C +D = 8.5 +0.1 = 8.6

minimum hole = A -B = 4.8 -0.4 = 4.4

Allowance = 8.6 -4.4 = 4.2

For an interference fit, the allowance is negative.

Design rationale can benefit interface design by providing a clear and logical explanation of design choices and how they meet the requirements of the project. However, design rationale may be rejected by design teams if it is seen as overly prescriptive or rigid, or if it is not well-aligned with the goals and objectives of the project.

Design rationale can help the design team to better understand the design and make informed decisions about changes or improvements.
QOC (Questions, Options, Criteria) design rationale is a method for structuring design decisions and the rationale behind them. It involves identifying the key questions that need to be answered in the design process, generating a range of possible options for addressing those questions, and then evaluating those options against a set of criteria.
For example, if the design team is tasked with creating a user interface for a mobile app, they might begin by asking questions like "What features should the app include?" and "How should the app be organized?" They could then generate a range of options for each question, such as "Include a search function, a messaging function, and a profile function" or "Organize the app into tabs for each function." Finally, they could evaluate these options against criteria such as usability, efficiency, and aesthetic appeal to make informed design decisions.

This question is incomplete, the complete question is;

An air-standard Carnot cycle is executed in a closed system between the temperature limits of 350 and 1200 K. The pressures before and after the isothermal compression are 150 and 300 kPa, respectively. If the net work output per cycle is 0.5 kJ, determine (a) the maximum pressure in the cycle, (b) the heat transfer to air, and (c) the mass of air. Assume variable specific heats for air.

Answer:

a) the maximum pressure in the cycle is 30.01 Mpa

b) the heat transfer to air is 0.7058 KJ

c) mass of Air is 0.002957 kg

Explanation:

Given the data in the question;

We find the relative pressure of air at 1200 K (T1) and 350 K ( T4)

so from the "ideal gas properties of air table"

Pr1 = 238

Pr4 = 2.379

we know that Pressure P1 is only maximum at the beginning of the expansion process,

so

now we express the relative pressure and pressure relation for the process 4-1

P1 = (Pr2/Pr4)P4

so we substitute

P1 = (238/2.379)300 kPa

P1 = 30012.6 kPa = 30.01 Mpa

Therefore the maximum pressure in the cycle is 30.01 Mpa

b)

the Thermal heat efficiency of the Carnot cycle is expressed as;

ηth = 1 - (TL/TH)

we substitute

ηth = 1 - (350K/1200K)

ηth = 1 - 0.2916

ηth = 0.7084

now we find the heat transferred

Qin = W_net.out / ηth

given that the net work output per cycle is 0.5 kJ

we substitute

Qin = 0.5 / 0.7084

Qin = 0.7058 KJ

Therefore, the heat transfer to air is 0.7058 KJ

c)

first lets express the change in entropy for process 3 - 4

S4 - S3 = (S°4 - S°3) - R.In(P4/P3)

S4 - S3 = - (0.287 kJ/Kg.K) In(300/150)kPa

= -0.1989 Kj/Kg.K = S1 - S2

so that; S2 - S1 = 0.1989 Kj/Kg.K

Next we find the net work output per unit mass for the Carnot cycle

W"_netout = (S2 - S1)(TH - TL)

we substitute

W"_netout = ( 0.1989 Kj/Kg.K )( 1200 - 350)K

= 169.065 kJ/kg

Finally we find the mass

mass m = W_ net.out /  W"_netout

we substitute

m = 0.5 / 169.065

m = 0.002957 kg

Therefore, mass of Air is 0.002957 kg

To be considered a complete warm-up cycle, the engine must reach a temperature that is optimal for its efficient and safe operation.

The specific temperature required for a complete warm-up cycle may vary depending on the engine type, fuel used, and other factors. Generally, the engine should reach its normal operating temperature, which is typically around 195-220 degrees Fahrenheit (90-105 degrees Celsius) for most gasoline-powered vehicles. This temperature allows the engine to operate efficiently, burn fuel effectively, and minimize wear and tear on engine components. However, it's important to consult the manufacturer's guidelines or the vehicle's owner's manual for the recommended warm-up temperature specific to your engine model.

Answer:

The minimum allowable bolt diameter required to support an applied load of P = 450 kN is 45.7 milimeters.

Explanation:

The complete statement of this question is "Five bolts are used in the connection between the axial member and the support. The ultimate shear strength of the bolts is 320 MPa, and a factor of safety of 4.2 is required with respect to fracture. Determine the minimum allowable bolt diameter required to support an applied load of P = 450 kN"

Each bolt is subjected to shear forces. In this case, safety factor is the ratio of the ultimate shear strength to maximum allowable shear stress. That is to say:

\(n = \frac{S_{uts}}{\tau_{max}}\)

Where:

\(n\) - Safety factor, dimensionless.

\(S_{uts}\) - Ultimate shear strength, measured in pascals.

\(\tau_{max}\) - Maximum allowable shear stress, measured in pascals.

The maximum allowable shear stress is consequently cleared and computed: (\(n = 4.2\), \(S_{uts} = 320\times 10^{6}\,Pa\))

\(\tau_{max} = \frac{S_{uts}}{n}\)

\(\tau_{max} = \frac{320\times 10^{6}\,Pa}{4.2}\)

\(\tau_{max} = 76.190\times 10^{6}\,Pa\)

Since each bolt has a circular cross section area and assuming the shear stress is not distributed uniformly, shear stress is calculated by:

\(\tau_{max} = \frac{4}{3} \cdot \frac{V}{A}\)

Where:

\(\tau_{max}\) - Maximum allowable shear stress, measured in pascals.

\(V\) - Shear force, measured in kilonewtons.

\(A\) - Cross section area, measured in square meters.

As connection consist on five bolts, shear force is equal to a fifth of the applied load. That is:

\(V = \frac{P}{5}\)

\(V = \frac{450\,kN}{5}\)

\(V = 90\,kN\)

The minimum allowable cross section area is cleared in the shearing stress equation:

\(A = \frac{4}{3}\cdot \frac{V}{\tau_{max}}\)

If \(V = 90\,kN\) and \(\tau_{max} = 76.190\times 10^{3}\,kPa\), the minimum allowable cross section area is:

\(A = \frac{4}{3} \cdot \frac{90\,kN}{76.190\times 10^{3}\,kPa}\)

\(A = 1.640\times 10^{-3}\,m^{2}\)

The minimum allowable cross section area can be determined in terms of minimum allowable bolt diameter by means of this expression:

\(A = \frac{\pi}{4}\cdot D^{2}\)

The diameter is now cleared and computed:

\(D = \sqrt{\frac{4}{\pi}\cdot A}\)

\(D =\sqrt{\frac{4}{\pi}\cdot (1.640\times 10^{-3}\,m^{2})\)

\(D = 0.0457\,m\)

\(D = 45.7\,mm\)

The minimum allowable bolt diameter required to support an applied load of P = 450 kN is 45.7 milimeters.

We have that the minimum allowable bolt diameter is mathematically given as

From the question we are told

Generally the equation for the stress   is mathematically given as

\(\mu= 320/4.2 \\\\\mu= 76.190 N/mm^2\)

Therefore

Force = Stress * area

Force = P/2

F= 425,000 N / 2 = 212,500 N

Hence area of each bolt is given as

212,500 = 76.190*( 5* area of each bolt)

area of each bolt = 557.815

Since

area of each bolt=\pi*d^2/4

\pi*d^2/4 = 557.815

Power delivered to the runner is approximately 2.34 MW and the hydraulic efficiency of the Pelton wheel is approximately 88%.

Step-by-step explanation:

Calculate the coefficient of bucket using the bucket deflection angle:

cos(170°/2) = cos(85°) = 0.087

coefficient of bucket = 1 - 0.087 = 0.913

Calculate the mass flow rate:

mass flow rate = density x volumetric flow rate

= 1000 kg/m3 x 1 m3/s

= 1000 kg/s

Calculate the power delivered to the runner:

Power = mass flow rate x acceleration due to gravity x head x efficiency

= 1000 kg/s x 9.81 m/s2 x 270 m x 0.98 x 0.913

= 2341596.6 W

≈ 2.34 MW

Calculate the hydraulic efficiency:

Hydraulic efficiency = power output / power input

= 2.34 MW / (1000 kg/s x 9.81 m/s2 x 270 m x 0.98)

≈ 0.88 or 88%

The term that refers to agreement as to what type of information the language is conveying is "semantic".

Semantic refers to the study of meaning in language, specifically the meaning of words, phrases, and sentences. It focuses on understanding how language conveys information and the relationship between words and their meanings.

For example, consider the sentence "The cat is on the mat." In a semantic analysis, we would examine the meanings of the words "cat," "on," and "mat" to understand the message being conveyed. We would determine that the sentence is expressing the location of the cat on the mat.

In contrast, the other options mentioned in the question have different meanings:

- Syntactic refers to the study of sentence structure and how words are combined to form grammatically correct sentences. It does not specifically focus on the meaning of the words.

- Logical refers to the study of reasoning and how statements relate to each other in a logical manner. It is concerned with the validity and soundness of arguments, rather than the specific meaning of words.

- Lexical refers to the study of words and their meanings. It examines the vocabulary of a language and how words are used to convey meaning. While lexical analysis is related to semantic analysis, it is not specifically concerned with the agreement of the type of information being conveyed.
