a coil of 1000 turns is wound on a laminated core of steel having a cross-section of 5 cm2 . the core has an air gap of 2 mm cut at right angle. what value of current is required to have an air gap flux density of .5t? permeability of steel may be taken as infinity. determine the coil inductance
Coil inductance is an important factor in electrical circuit design. It affects the impedance, or opposition to an electrical current, of a circuit. The determination of coil inductance is 0.314 H.
What is coil inductance and write its formula?
Coil inductance is the property of an electrical circuit which allows it to store electrical energy in the form of a magnetic field. It is measured in henrys (H) and is given by the equation:
L = μN^2A/l
Where L is the inductance, μ is the permeability of free space, N is the number of turns in the coil, A is the area of the coil, and l is the length of the coil. As the inductance of a circuit increases, the impedance increases as well. This means that more energy is required to produce the same amount of current in the circuit. Inductance is also used to control the flow of AC current in circuits. An inductor is a circuit component which uses inductance to oppose a change in the current in a circuit. This is used in circuits to delay or smooth out changes in the current, or to create a phase shift in the current. Inductance also plays a role in the design of electrical motors. The inductance of the windings in an electric motor affects the speed of the motor, and the amount of torque it can produce. Lastly, inductance is used to reduce the amount of noise in circuits, by providing a path for high frequency signals to flow away from the circuit. This helps to reduce the amount of interference in the circuit, and allows the circuit to operate more reliably.
Given,
N=1000 turns ;a=5cm² = 5×10⁻⁴m²; lg=2mm = 2 x 10⁻³m
B = 0.5T; μr = ∞
To find, Total ampere-turns required,
AT= B/μ0 x lg + B/μ₀μ r x li
AT = 0.5/4πx 10⁻⁷ x 2 x 10⁻³ + 0
AT = 796.
Current required, I = AT/T
AT = 796/1000 = 0⋅796A
coil inductance = NФ/I = N x B x a / I
= 1000 x 0.5 x 5 x 10⁻⁴/0.796
The coil inductance = 0.314 H

in the structure shown, an 8-mm-diameter pin is used at a, and 12-mm-diameter pins are used at b and d. knowing that the ultimate shearing stress is 100 mpa at all connections and that the ultimate normal stress is 250 mpa in each of the two links joining b and d, determine the allowable load p if an overall factor of safety of 2.7 is desired.
To determine the allowable load P, we need to calculate the shear and normal stresses at each connection. The shear stress at each connection can be calculated using the equation τ = P/A, where P is the load and A is the area of the pin.
The normal stress at each connection can be calculated using the equation σ = P/A, where P is the load and A is the cross-sectional area of the link. Once the shear and normal stresses have been calculated, we can compare them to the ultimate shear and normal stresses to determine the allowable load. The allowable load will be the load that produces a shear and normal stress that is equal to or less than the ultimate shear and normal stresses, multiplied by the factor of safety.
To calculate the allowable load, we need to first calculate the shear and normal stresses at each connection. The shear stress at each connection can be calculated using the equation τ = P/A, where P is the load and A is the area of the pin. The area of the pin can be calculated using the equation A = πr2, where r is the radius of the pin. The normal stress at each connection can be calculated using the equation σ = P/A, where P is the load and A is the cross-sectional area of the link. The cross-sectional area of the link can be calculated using the equation A = bh, where b is the width of the link and h is the height of the link. Once the shear and normal stresses have been calculated, we can compare them to the ultimate shear and normal stresses to determine the allowable load. The allowable load will be the load that produces a shear and normal stress that is equal to or less than the ultimate shear and normal stresses, multiplied by the factor of safety.

the hydraulic lit in a car repair shop has an output diameter of 22.8 cm and is to lift cars up to 1620 kg. determine the fluid gage pressure in kpa that must be maintained
Answer:
To determine the fluid gage pressure that must be maintained in the hydraulic lift, you need to use the equation for force, which is:
Pressure = Force / Area
Where:
Pressure is in units of kPa (kilopascals)
Force is in units of N (newtons) and is equal to the weight of the car (1620 kg) multiplied by the acceleration due to gravity (9.81 m/s^2)
Area is in units of m^2 (square meters) and is equal to the output diameter of the lift (22.8 cm) converted to meters (0.228 m)
So the pressure that must be maintained is:
Pressure = (1620 kg * 9.81 m/s^2) / (0.228 m^2)
Pressure = (15,847.2 N) / (0.228 m^2)
Pressure = 69,844 kPa
So the fluid gage pressure that must be maintained is 69,844 kPa.

compare distributed database design strategies with respect to reliability, expandability, communications, overhead costs, manageability, and data consistency.
A distributed database refers to a database management system in which all databases are not connected on the same server.
What are the characteristics of distributed database?In comparison to centralized databases, distributed databases are more reliable. In the event of a database failure in a centralized database, the system comes to a halt. When a distributed database fails, the system continues to function, albeit with reduced performance until the problem is resolved.DDBMS's primary function is to keep track of data distribution, fragmentation, and replication by expanding the DDBMS catalog.Every read, regardless of which node it comes from, returns the data of the most recent write. Network failure is unavoidable in a distributed database, and a database must ensure that it can continue to run even if a partition fails.Often, expensive software is required to ensure data transparency and coordination across multiple sites.A distributed database management system (DDBMS) that is centralized manages distributed data as if it were stored in a single physical location. Data storage on-site lowers communication costs for data manipulation in distributed databases. In centralized databases, local data storage is not possible.To learn more about distributed database refer to :

determine the pressure at the deepest part of lake tahoe. the lake's surface elevation is 6225ft, assume that the conditions of the us standard atmosphere prevail at surface of the lake
Two conclusions can be inferred from the posed query, The distance from Lake Titicaca's surface to its deepest point is -922 feet.
The lake's deepest point is 11542 feet above sea level. Every distance above sea level is positive, and every distance below sea level is negative. Since the lake's lowest point is above sea level and its surface is above it, the Surface will therefore also be above sea level. Lake surface elevation is equal to the sum of the distance from the sea level to the deepest point in the lake and the distance from the surface to that point. = 11542 + 922. = 12464 feet. This means that the lake's elevation above sea level is 12464 feet. Two conclusions can be inferred from the posed query, The distance from Lake Titicaca's surface to its deepest point is -922 feet.

If I ue proper in-text citation and reference along with quotation mark for direct quote, I will not be plagiarizing.
You are not engaging in plagiarism if you have accurately cited the source when paraphrasing or quoting. However, using the right word is essential. You must abide by the rules of your chosen citation style (such as APA or MLA) to prevent plagiarism.
Do I need to cite the source when using a straight quotation but not a paraphrase?
According to some pupils, a source should only be cited when a direct quote is used. That's not right at all! Just because you put someone else's idea into your own words doesn't make it your own creation. Even if you paraphrase, the original author must still be given credit.
I'll also paraphrase: You are still plagiarizing if you change the order of words or concepts from the original source and incorporate parts of your own words mixed in with the original ones, even if you cite the source.

In a poll of 1000 randomly selected voters in a local election, 625 voters were against school bond measures. What is the sample proportion p? What is the margin of error m for the 99% confidence level?
Answer:
p = 625 / 1000 = 0.625
m = 2.576 * sqrt((0.625 * (1 - 0.625)) / 1000) = 0.03
Explanation:
The sample proportion p is the proportion of voters in the sample who were against school bond measures. To calculate this, divide the number of voters against the bond measures (625) by the total number of voters in the sample (1000):
p = 625 / 1000 = 0.625
The margin of error m for a sample proportion at the 99% confidence level can be calculated using the formula:
m = zsqrt(p(1-p)/n)
where z is the z-score for the desired level of confidence (for a 99% confidence level, z = 2.576), p is the sample proportion, and n is the sample size.
m = 2.576 * sqrt((0.625 * (1 - 0.625)) / 1000) = 0.03
So the margin of error for this poll at the 99% confidence level is 0.03.

Making decisions about core technology/protocols and circuit capacity during the technical design phase of a network is interconnected.
Network design is the planning and construction of a communications network. Network design begins with the identification of business and technical needs before network installation. Information concealment and hierarchical design are examples of time-tested principles that apply to good network architecture. Fundamental network protocols that use data encapsulation serve as one example of this. Changes in the lower layers have no impact on the upper layers since they operate in secrecy from the higher layers (i.e. applications). In addition to managing computer systems, they also install and support them. This list could also include intranets, network segments, local area networks (LANs), wide area networks (WANs), and other data transmission technologies.
