A 4.0 in. wide by 1.125 in. thick rectangular steel bar supports a load of P in tension. Determine:
• The stress in the bar for F = 32,000 lb.
• The load P that can be supported by the bar if the axial stress must not exceed 25,000 psi.
Answer:
a) The stress in the bar when F is 32,000 is approximately 7,100 psi
b) The load P that can be supported by the bar if the axial stress must not exceed is approximately 110,000 lb
Explanation:
The question topic relates to stresses in structures;
The given parameters of the steel bar are;
The width of the steel bar, W = 4.0 in.
The thickness of the steel bar, t = 1.125 in.
The formula for stress in a bar is given as follows;
\(Stress, \sigma = \dfrac{Force, F}{Area, A}\)
The cross sectional area of bar, A = W × t = 4.0 in. × 1.125 in. = 4.5 in.²
∴ The cross sectional area of bar, A = 4.5 in.²
a) The stress in the bar for F = 32,000 lb, is given as follows;
\(The \ stress \ in \ the \ bar , \sigma = \dfrac{ F}{A} = \dfrac{32,000 \ lb}{4.5 \ in.^2} = 7,111.\overline 1\)
The stress in the bar when F is 32,000 is σ = 7,111.\(\overline 1\) psi ≈ 7,100 psi
b) The load P that can be supported by the bar if the axial stress must not exceed, σ = 25,000 psi is given as follows;
\(\sigma = \dfrac{ P}{A}\)
Therefore;
P = σ × A = 25,000 psi × 4.5 in² = 112,500 lb
For the axial stress of 25,000 psi not to be exceeded, the maximum load that can be supported by the bar, P = 112,500 lb ≈ 110,000 lb.

Take a look around yourself. What do you see? Maybe books, chairs, a television, or even your clothes. All the day to day things that are man-made, you can be sure that an engineer helped make it. Engineers have shaped our world as we know it. There are many different kinds of engineers from chemical, mechanical, textile, civil, agricultural and structural engineers. Our civilization would be as advanced as the Stone Age without these people. This career demands a wide education of math and science. It is an ever-changing career with new advances in materials and the way products are produced. Engineering careers are very secure with respect to compensation. Regardless of this, it does have it’s disadvantages…show more content…
(Britannica 243) Another disadvantage of being an engineer is the actual status of being one. It is not looked upon as highly as other fields such as doctors and lawyers. Most of the time they are looked upon as nerds. In addition, most engineers are not promoted to high level positions such as presidents or top executives. They do not have the accounting or business education to do that particular job. This means that most engineers never get the opportunity to be their own boss. (Basta 22)
The job of an engineer itself is a creative job. The actual definition of an engineer is “The profession in which a knowledge of the mathematical and natural sciences gained by study, experience and practice is applied with judgment to develop ways to utilize the materials and forces of nature economically for the benefit of mankind.” (Bastas 24) In having the basic skills and experiences in math and science, an engineer is basically an inventor. They are given a problem and are depended on to come up with a solution. Whether it be a new chemical, a mechanical part, or even a whole new system such as computer operating program, engineers are the problem solvers of our materialistic society.
There are four major types of essay and they are the Descriptive, Argumentative, Expository and the Narrative essay.
What is an essay?An essay is generally are a piece of writing that gives an argument, educates or entertains a reader about a specific topic.
Writing an essay about engineering is to educate people about the field of study, and therefore, falls under the Expository essay.

High-quality surface finish is subtractive manufacturing most effective at producing.
What is subtractive manufacturing?
A broad phrase for different controlled machining and material removal methods, subtractive manufacturing refers to the shaping of solid blocks, bars, and rods of plastic, metal, or other materials by removing material through cutting, boring, drilling, and grinding.
Examples of subtractive metal-cutting operations that are typically done on specialist machinery include lathe turning, milling, drilling, sawing, thread cutting, and gear cutting.
Cutting away from a solid block of material is known as subtractive fabrication or subtractive manufacturing. It might be a block made of, say, wood, plastic, or metal. Subtractive manufacturing uses a milling machine to hollow out or cut a piece of metal or plastic.
Cutting the material manually is another method of subtractive manufacturing. before the industrial revolution, in actuality.

What evidence from the text supports the author's position that Africa is a leader in the fight against climate change?
It's worth noting that the situation may have evolved since my last update in September 2021. To provide specific evidence from a text supporting Africa's leadership in the fight against climate change.
Africa has been actively promoting renewable energy projects. For example, the continent has abundant solar and wind resources, and many countries have invested in solar and wind farms. This shift towards renewable energy sources demonstrates Africa's commitment to reducing carbon emissions and combating climate change.
Africa is particularly vulnerable to the impacts of climate change, such as droughts, floods, and desertification. To cope with these challenges, African countries have developed adaptation strategies. For instance, they have invested in water management systems, climate-resilient agriculture, and early warning systems for natural disasters.

Who’s duty is it to design an efficient and functional foundation
Answer:
The duty to design an efficient and functional building foundation typically falls under the responsibility of a civil engineer
Civil engineers are responsible for designing and constructing the foundation of a building. They have the expertise and knowledge to analyze the soil conditions, the load-bearing capacity required, and the type of foundation that is most appropriate for the specific structure. They are trained to design foundations that will ensure the stability and safety of the building for its intended use.
While architects play an important role in designing the overall aesthetics and functionality of a building, they are not typically trained in the technical aspects of foundation design. Contractors and masons, on the other hand, are responsible for executing the construction process, but they are not necessarily equipped to design the foundation.
Therefore, it is the duty of a civil engineer to design an efficient and functional building foundation to ensure the long-term stability and safety of the structure.

A 1-mm-thick sheet of FCC iron is used to contain nitrogen in a heat exchanger at 1200 °C. The concentration of N at one surface is 0.04 atomic percent and the concentration at the second surface is 0.005 atomic percent. Determine the flux of nitrogen through the foil in N atoms/(cm2 · s)?
The flux of nitrogen through the foil is 1.225 x \(10^{-7\) atomic/(\(cm^2\)*s).
What is electric flux?The electric flux is defined as the total number of electric field lines passing through a given area in a given unit of time.
To solve this problem, we can use Fick's first law of diffusion, which relates the flux of atoms to the concentration gradient:
J = -D x (dC/dx)
Where J is the flux of atoms (in atoms/(cm^2*s)), D is the diffusion coefficient, C is the concentration of nitrogen (in atomic percent), and x is the distance across the foil.
We can assume that the diffusion coefficient for nitrogen in FCC iron at 1200 °C is approximately 3.5 x \(10^{-7\) \(cm^2\)/s. We can also assume that the foil is flat and that the concentration gradient is uniform across its thickness.
Using these assumptions and the given concentrations, we can calculate the concentration gradient:
dC/dx = (0.04 - 0.005) / (1 mm) = 0.035 / 0.1 cm = 0.35 atomic percent/cm
Now we can plug in the values into Fick's first law of diffusion:
J = - (3.5 x 10^-7 cm^2/s) * (0.35 atomic percent/cm)
J = - 1.225 x \(10^{-7\) atomic/(\(cm^2\)*s).
Since the flux is negative, we can interpret this as meaning that nitrogen is diffusing from the surface with the higher concentration (0.04 atomic percent) to the surface with the lower concentration (0.005 atomic percent), as we would expect.
Therefore, the flux of nitrogen through the foil is 1.225 x \(10^{-7\) atomic/(\(cm^2\)*s).
