Draw the given block in first angle orthographic projection looking in the direction of arrow X as the front elevation​

To determine the values at the throat and exit of a converging-diverging nozzle with given conditions, follow these steps:

a) Static pressure at the throat: Since throat Mach number (Mt) is 1, use isentropic relations: P_t/P_0 = (1 + (γ-1)/2 * Mt^2)^(-γ/(γ-1)). Given P_0 = 1.5 MPa and γ = 1.4 (for air), calculate P_t = 0.5293 MPa.

b) Static temperature at the throat: Similarly, T_t/T_0 = (1 + (γ-1)/2 * Mt^2)^(-1). Given T_0 = 900 K, calculate T_t = 635.71 K.

c) Static pressure at the exit: Use the exit Mach number (Me = 2.5) and isentropic relations to find P_e/P_0 = 0.0666. Calculate P_e = 0.0999 MPa.

d) Static temperature at the exit: Using Me = 2.5, find T_e/T_0 = 0.2842. Calculate T_e = 255.78 K.

e) Mass flow rate through the nozzle: m_dot = A_t * P_0 * sqrt(γ/R*T_0) * (1 + (γ-1)/2)^((-γ-1)/(2*(γ-1))). Given A_t = 30 cm^2 (0.003 m^2), R = 287 J/(kg*K), calculate m_dot = 9.04 kg/s.

To determine the standard bar size for the specified diameter, we need to compare the calculated diameter of 0.961 in with the standard sizes available in the market.

In the United States, standard bar sizes are typically specified in terms of eighths of an inch (1/8"). For example, a #4 bar corresponds to a diameter of 4/8" or 1/2". A #8 bar corresponds to a diameter of 8/8" or 1".

To find the closest standard bar size to 0.961 in, we can convert the decimal value to eighths of an inch by multiplying it by 8.

0.961 in * 8 = 7.688 eighths of an inch

The closest standard bar size to this value is a #8 bar, which has a diameter of 1 inch. Therefore, a #8 bar should be chosen for this design.

It's important to note that in some cases, it may be necessary to choose a custom size or to adjust the design to accommodate a standard bar size.

False, SQL injection attacks are not isolated to custom applications. Administrators can take measures to prevent them, but they can occur in various types of applications, including off-the-shelf and open-source software. It is essential to implement proper input validation and parameterized queries to mitigate SQL injection risks.

Explanation:

SQL injection attacks are not isolated to custom applications only. They can occur in any application that uses SQL databases and allows user input to be concatenated directly into SQL queries without proper validation and sanitization. This includes off-the-shelf or third-party applications, as well as custom applications.

SQL injection attacks occur when an attacker is able to manipulate SQL queries through unvalidated user input, such as input fields in a web form. This allows the attacker to execute malicious SQL queries, potentially gaining unauthorized access to the database and extracting sensitive data or even modifying data.

Administrators can take steps to prevent SQL injection attacks, regardless of whether an application is custom or off-the-shelf. These steps include using prepared statements or parameterized queries in code, validating and sanitizing user input, and applying least privilege principles to database users to limit their access to only necessary permissions.

It's important for administrators to understand that SQL injection attacks are not limited to custom applications and can occur in any application that uses SQL databases. Therefore, proper security measures should be implemented to protect against SQL injection attacks in all applications, regardless of their origin.

Hence, False, SQL injection attacks are not isolated to custom applications.

Answer:

True

Explanation:

The order of precedence in this expression is first to evaluate "Not(rate = .10)" because it contains parentheses and the "Not" operator, then to evaluate the "and" operator, and finally to evaluate the "or" operator.

"Not(rate = .10)" evaluates to True because the value of "rate" is .20, which is not equal to .10.

Next, we can evaluate "Sales >= 250 and expenses <> 500". Since "expenses" equals 500, the expression "expenses <> 500" is False. Therefore, the entire expression "Sales >= 250 and expenses <> 500" is False.

Finally, we can evaluate the "or" operator between the True value from "Not(rate = .10)" and the False value from "Sales >= 250 and expenses <> 500". The result is True, because at least one of the conditions is True.

Therefore, the statement "Sales >= 250 and expenses <> 500 or Not(rate = .10)" is True.

When measured from the upper surface of the handrail to the tread must be the minimum height for handrails is 34 inches, and the maximum height is 38 inches.

According to the International Building Code (IBC), handrails are required on stairways that have four or more risers. The height of the handrail is measured from the upper surface of the handrail to the tread or walking surface of the stair. The minimum height for handrails is 34 inches, and the maximum height is 38 inches, measured from the top of the gripping surface of the handrail to the tread.

The reason for this height range is to ensure that the handrail is at a comfortable height for most people to grip and use for support while climbing or descending the stairs. The handrail should also be continuous along the entire length of the stairs, including any landings or intermediate platforms. In addition to the height requirements, the handrail should also be able to withstand a force of 200 pounds applied in any direction at any point along the railing.

The handrail must also be securely anchored to the wall or support structure to prevent it from becoming loose or unstable. Ensuring that handrails meet these height and strength requirements is essential for providing a safe and accessible environment for people using stairs. By following these guidelines, building owners and designers can help prevent accidents and injuries, and ensure compliance with building codes and regulations.

To determine the magnitude p (in kn) required to displace the roller to the right 0.368 mm, we can use the formula:

p = (3 x A x E x δ) / L
Where:
- A is the cross-sectional area of each member (206 mm2)
- E is the modulus of elasticity of A-36 steel (200 GPa)
- δ is the displacement of the roller to the right (0.368 mm)
- L is the length of each member (which we assume to be equalPlugging in the values, we get:p = (3 x 206 x 10^-6 m2 x 200 x 10^9 N/m2 x 0.368 x 10^-3 m) / LSimplifying, we get:p = 45.514 N / LTo get the value of p in kilonewtons (kN), we need to divide by 1000:p = 0.0455 kN LSince we don't have the value of L, we cannot determine the exact value of p. However, we can say that the magnitude of p required to displace the roller to the right 0.368 mm will be directly proportional to the length of each member.To calculate the magnitude P required to displace the roller to the right 0.368 mm in a truss made of three A-36 steel members with a cross-sectional area of 206 mm², you need to consider the material's modulus of magnitude and the geometry of the truss. The modulus of elasticity (E) for A-36 steel is approximately 200 GPa (Gigapascals). The next step would be to analyze the geometry of the truss and calculate the deformation in the members using the given displacement. Once the deformation is obtained, you can apply Hooke's Law to find the internal forces in the members.
Hooke's Law states that the internal force (F) in a member is equal to the product of the member's elongation (ΔL), cross-sectional area (A), and modulus of elasticity (E), divided by the original length of the member (L):
F = (ΔL * A * E) / LTo calculate the magnitude P, you would need to find the equilibrium of forces in the truss and consider the forces in the members. With the information provided, a complete answer cannot be given. Please provide the truss geometry and member lengths for further assistance.

Objects permit data hiding, which means they can prevent functions outside the class from changing some or all of the data. Therefore, the answer to your question is "a) changing".

Explanation:

In object-oriented programming (OOP), data hiding is a concept that allows objects (instances of a class) to encapsulate and protect their internal data from being accessed or modified directly by external functions or code. Data hiding is achieved by using access modifiers, such as private or protected, to restrict the visibility and access of class members (i.e., variables, properties, and methods) from outside the class.

Functions outside the class can still access the data, but they cannot modify it without using specific methods provided by the class. This feature is crucial for protecting the integrity and consistency of the data in object-oriented programming.

When data is hidden using access modifiers, it means that external functions or code outside the class cannot directly modify the hidden data. This includes changing the value of the data, as mentioned in the question. Therefore, the correct answer is "a) changing." External functions or code can still access and read the value of the data if the access modifier allows for it, but they cannot modify it directly.

It's worth noting that data hiding is an important principle of OOP as it promotes encapsulation and abstraction, which helps in achieving better code organization, maintainability, and security. By hiding the internal data of objects, classes can have better control over how the data is accessed and modified, preventing unintended changes that may lead to bugs or security vulnerabilities.

Therefore, Objects permit data hiding, which means they can prevent functions outside the class from changing some or all of the data.

Assuming the kinetic and potential energy changes to be negligible  final temperature is -21.651°C

We can use the polytropic process equation to solve for the unknowns:

P1V1ⁿ = P2V2  ⁿ

where

First, we need to find  the  V1. We can use the ideal gas law:

PV = mRT

where

Solving for V1:

V1 = mRT1  /P1

Next, we can solve for the final volume V2 using the polytropic process equation:

V2 = V1 x    (P1/ P2)^(1/n)

Now, we can solve for the work done on the gas during the process:

W = (P2 V2 - P1  V1)/  (1- n)

Now , we can use the first law of thermodynamics to   find   the change in internal energy

ΔU = Q - W

where Q is the heat added to the system, which we assume to be zero in this case because the problem statement says kinetic and potential energy changes are negligible.

ΔU = -W

Now,  we can use the specific heat at  constant volume to solve for the change in temperature

ΔU = m  cv ΔT

ΔT = ΔU /(m cv)

where m is the mass of gas.

Hence,

V1 = mRT1/P1 = (0.744 kJ/kg-K x    293 K)/(100 kPa)

= 2.1719 m³/kg

V2 = V1  x    (P1/P2)^(1/n) = 2.1719 m₃/kg   x   (100 kPa/600 kPa)^(1/1.3)

= 0.4325 m ³/  kg

W = (P2V2 - P1V1)/(1-n) =  (600 kPa x     0.4325 m³/kg - 100 kPa x   2.1719 m³/kg)/(1-1.3) =

-30.969 kJ/kg

ΔT = ΔU/ (m cv) = -30.969 kJ/kg / (1 kg x    0.744 kJ/kg-K) =  - 41.651 K
