a. The stress in the femur is calculated to be approximately 24.32 MPa.
b. The amount of shortening due to the load is calculated to be approximately 1.56 mm.
a. To calculate the stress in the femur, we need to determine the cross-sectional area of the femur and apply the formula: Stress = Force / Area. The cross-sectional area of the femur can be calculated as the difference between the areas of the outer and inner circles. The stress is then determined by dividing the applied load by the cross-sectional area.
b. To calculate the amount of shortening, we use Hooke's Law, which states that the amount of deformation is directly proportional to the applied force and the material's Young's modulus. The formula for calculating the amount of shortening is given by: Shortening = (Force * Length) / (Cross-sectional area * Young's modulus). By substituting the given values, we can determine the amount of shortening caused by the load.
Note: The given values (diameter, hollow center diameter, and length) are used to calculate the cross-sectional area and the total cross-sectional area of the femur. Young's modulus (Y) is also provided to calculate the amount of shortening.

A student borrows $60,000 for business school at 6.5% stated annual interest with equal monthly payments over 10 years. Consider this as a loan with no payments or interest during school so that the problem structure is equivalent to a standard loan received one period before the first payment. How much is the monthly payment?
Answer:
$681.29
Explanation:
The amortization formula seems to apply. The monthly payment on a loan of P at rate r for t years is ...
A = P(r/10)/(1 -(1 +r/12)^(-12t))
For the given loan parameters, the monthly payment is ...
A = $60,000(0.065/12)/(1 -(1 +0.065/12)^(-12·10)) ≈ $681.29
The monthly payment is $681.29.
Choose the term that matches the definition. : a programming language that uses instructions that are close to everyday English
The term that matches the definition is "high-level programming language."
In a high-level programming language, the instructions and syntax are designed to be close to everyday English, making it easier for programmers to read, write, and understand the code. High-level programming languages abstract away many low-level details and complexities of computer hardware, providing a more intuitive and human-friendly approach to programming.
These languages utilize a vocabulary and syntax that resemble natural language, with keywords and constructs that align with common concepts and actions.
For example, high-level languages may use keywords such as "if," "while," and "for" to represent conditional statements, loops, and iteration. Variables and functions are often named using descriptive words or phrases, allowing for more expressive and self-explanatory code.
By using a high-level programming language, developers can focus on the logical aspects of their programs rather than getting lost in intricate machine-level details. This abstraction enables faster development, better code readability, and increased productivity.
Examples of high-level programming languages include Python, Java, C++, and JavaScript. These languages provide extensive libraries, frameworks, and tools that simplify complex tasks and provide a wide range of functionalities. The use of natural language-like syntax in these languages enhances the programmer's ability to communicate intentions and ideas effectively.
In contrast, low-level programming languages, such as assembly or machine code, use instructions that directly correspond to the underlying hardware architecture, offering more control but requiring a deep understanding of computer internals. High-level languages bridge this gap and make programming more accessible and user-friendly for developers.

V(t)=8sin(wt)−14sin(2wt)+3sin(5wt) −v(t)=8sin(wt)−14cos(wt) −v(t)=8sin(wt−45∘ )−6cos(wt+10(∘ )+4sin(2wt−30∘ )
The given expression consists of several terms involving sine and cosine functions with different angular frequencies and phase shifts. Let's break down each term separately and analyze its properties.
This term represents a sine function with amplitude 8 and angular frequency w. The value of w is not provided in the question, so we cannot determine its exact value. However, we can say that as t increases, the argument of the sine function (wt) will increase, causing the function to oscillate. This term represents a sine function with amplitude -14 and angular frequency 2w. The negative sign indicates that the function is reflected about the x-axis, which means it is upside down compared to a regular sine function. The angular frequency of 2w means that the function oscillates twice as fast as the previous term.
This term represents a sine function with amplitude 3 and angular frequency 5w. Similar to the previous term, this function is also reflected about the x-axis. The angular frequency of 5w means that it oscillates even faster compared to the previous terms. This term combines sine and cosine functions. It represents the difference between a sine function with amplitude 8 and a cosine function with amplitude 14, both having the same angular frequency w. The sine and cosine functions have a phase difference of 90 degrees, which means that at any given time t, the sine and cosine functions will have different values. Overall, the given expression consists of several sine and cosine functions with different amplitudes, angular frequencies, and phase shifts.

• Your plants are showing signs of iron deficiency. You check the soil
pH and it is 8.0. What would most likely be the best way to eliminate
the iron deficiency and why?
If your plants show signs of iron deficiency in them, the best way to eliminate the iron deficiency is by applying a foliar spray and lower the pH.
What is pH?pH is simply an abbreviation for the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions in a particular solution.
This ultimately implies that, a pH can be used to measure and specify the acidity, neutrality or basicity (alkalinity) of any chemical solution. On a pH scale, a chemical solution or substance with a pH of 7 is said to be neutral, a chemical solution with a pH below 7 is acidic and it's basic (alkaline) when it's pH is above 7.
In conclusion, we can infer and logically deduce that if your plants show signs of iron deficiency in them, the best way to eliminate the iron deficiency is by applying a foliar spray and lower the pH.

Answer: 25 ft
Explanation:
For a triangle, the area is given by

cubical tank 1 meter on each edge is filled with water at 20 degrees C. A cubical pure copper block 0.46 meters on each edge with an initial temperature of 100 degrees C is quickly submerged in the water, causing an amount of water equal to the volume of the smaller cube to spill from the tank. An insulated cover is placed on the tank. The tank is adiabatic. Estimate the equilibrium temperature of the system (block + water). Be sure to state all applicable assumptions.
Answer:
final temperature = 26.5°
Explanation:
Initial volume of water is 1 x 1 x 1 = 1 \(m^{3}\)
Initial temperature of water = 20° C
Density of water = 1000 kg/\(m^{3}\)
volume of copper block = 0.46 x 0.46 x 0.46 = 0.097 \(m^{3}\)
Initial temperature of copper block = 100° C
Density of copper = 8960 kg/\(m^{3}\)
Final volume of water = 1 - 0.097 = 0.903 \(m^{3}\)
Assumptions:
since tank is adiabatic, there's no heat gain or loss through the wallsthe tank is perfectly full, leaving no room for cooling airtotal heat energy within the tank will be the summation of the heat energy of the copper and the water remaining in the tank.mass of water remaining in the tank will be density x volume = 1000 x 0.903 = 903 kg
specific heat capacity of water c = 4186 J/K-kg
heat content of water left Hw = mcT = 903 x 4186 x 20 = 75.59 Mega-joules
mass of copper will be density x volume = 8960 x 0.097 = 869.12 kg
specific heat capacity of copper is 385 J/K-kg
heat content of copper Hc = mcT = 869.12 x 385 x 100 = 33.46 Mega-joules
total heat in the system = 75.59 + 33.46 = 109.05 Mega-joules
this heat will be distributed in the entire system
heat energy of water within the system = mcT
where T is the final temperature
= 903 x 4186 x T = 3779958T
for copper, heat will be
mcT = 869.12 x 385 = 334611.2T
these component heats will sum up to the final heat of the system, i.e
3779958T + 334611.2T = 109.05 x \(10^{6}\)
4114569.2T = 109.05 x \(10^{6}\)

Suppose that a wing component on an aircraft is fabricated from an aluminum alloy that has a plane strain fracture toughness of 29 MPa (26.39 ksi). It has been determined that fracture results at a stress of 101 MPa (14650 psi) when the maximum internal crack length is 7.5 mm (0.2953 in.). For this same component and alloy, compute the stress level at which fracture will occur for a critical internal crack length of 5 mm (0.1969 in.).
Answer:
123.46 MPa
Explanation:
( Aluminum alloy Plane strain fracture toughness = 29 MPa ( 26.39 ksi )
Fracture results at a stress of 101 MPa ( psi )
maximum internal crack length = 7.5 mm ( 0.2953 in )
Compute the stress level at which fracture will occur for a critical internal crack length of 5 mm ( 0.1969 in )
Y = \(\frac{KI_{c} }{\alpha \sqrt{\pi a} }\)
Y = 29 / 101 √π [( 7.5 * 10^-3 ) / 2]
= 29 / 101 √ 0.01178097245 = 29 / ( 101 * 0.1085 )
= 2.65
hence the stress level at which fracture will occur for a critical internal crack length of 5 mm
∝c = \(\frac{KI_{c} }{y\sqrt{\pi a} }\)
Given; y = 2.65 , KIc = 29, a = ( 5 * 10^-3 ) / 2 = 0.0025
hence ∝c = 29 / 2.65 \(\sqrt{\pi *0.0025}\)
= 29 / 0.2349 ≈ 123.46 MPa

The distribution is normal (examples: normal / t12 / chisquare4 / F5,6). The test statistic has value TS= . Testing at significance level α = 0.01, the rejection region is: less than and greater than (2 dec places). Since the test statistic (is in/is not in) the rejection region, there (is evidence/is no evidence) to reject the null hypothesis, H0. There (is sufficient/is insufficient) evidence to suggest that the average hardness depth, μ, is different to 4.5 mm. Were any assumptions required in order for this inference to be valid? a: No - the Central Limit Theorem applies, which states the sampling distribution is normal for any population distribution. b: Yes - the population distribution must be normally distributed.
