5.20 necking in a tensile specimen begins at an engineering strain of 0.20. the corresponding engineering stress at this point is 1000 mpa. determine the work hardening rate at the beginning of necking.

The wind velocity on the downstream side of the wind turbine is approximately 7.7 m/s (rounded to one decimal place).

To find the wind velocity on the downstream side of the wind turbine, we can use the concept of conservation of mass and energy.

The available kinetic energy of the wind is proportional to the square of the wind velocity. Since the turbine extracts 35% of the available kinetic energy, the remaining energy after the turbine is 65% (100% - 35%).

Let's assume the wind velocity on the downstream side of the turbine is V_d.

According to the conservation of energy:

(1/2) * ρ * A * (V_u^2) * 0.35 = (1/2) * ρ * A * (V_d^2) * 0.65

ρ is the air density (assumed constant)

A is the cross-sectional area of the turbine (assumed constant)

V_u is the wind velocity on the upstream side of the turbine

V_d is the wind velocity on the downstream side of the turbine

Since the air density, cross-sectional area, and turbine efficiency are constant, we can simplify the equation:

V_u^2 * 0.35 = V_d^2 * 0.65

Dividing both sides by 0.35 and rearranging the equation, we get:

V_d^2 = (V_u^2 * 0.35) / 0.65

Taking the square root of both sides, we find:

V_d = sqrt((V_u^2 * 0.35) / 0.65)

Substituting the given value V_u = 9.3 m/s into the equation:

V_d = sqrt((9.3^2 * 0.35) / 0.65) ≈ 7.719 m/s

Thus, the appropriate answer is approximately 7.7 m/s (rounded to one decimal place).

For the study described in question 4a) that examines the relationship between college students' need for achievement and their grade point averages, the appropriate statistical test would be a correlation analysis.  

In question 4b), where the relationship between gender and preference for Ford, Chevrolet, and Chrysler cars is studied, the appropriate statistical test would be a chi-square test of independence.

Lastly, in question 4c), where a person claims to have psychic powers and predicts the outcome of a roll of a die, a binomial test would be appropriate.  

In question 4a), the need for achievement and grade point averages are both continuous variables. To analyze their relationship, a correlation analysis, such as Pearson's correlation coefficient, would be suitable. This test quantifies the strength and direction of the linear relationship between the two variables. It helps determine if there is a significant association between students' need for achievement and their grade point averages. In question 4b), the variables under study are gender (a categorical variable) and car preference (another categorical variable). To assess the relationship between these variables, a chi-square test of independence is appropriate. This test allows us to determine if there is a significant association between gender and car preference. It helps us understand if there are differences in car preferences between men and women. In question 4c), the person's claim of psychic powers is tested based on their ability to predict the outcome of a roll of a die. Since the person's predictions are binary (either correct or incorrect), a binomial test is suitable. This test determines if the success rate significantly deviates from what would be expected by chance. Using an alpha level of 0.05, the binomial test can help evaluate the person's claim and determine if their predictions are statistically significant or due to chance.

The value of the isentropic efficiency of the turbine is 82.17%.

The formula for isentropic efficiency of a turbine is:

ηisentropic=(h1−h2s)/(h1−h2)

where h1 is the inlet enthalpy, h2s is the exit enthalpy for an isentropic process, and h2 is the actual exit enthalpy.

Using Steam Tables, the enthalpies at the given pressures and temperatures are:

h1 = 3514.1 kJ/kg (from 4 MPa)

h2s = 2823.2 kJ/kg (from 120 kPa, using entropy at h1)

h2 = 2816.2 kJ/kg (from 120 kPa and the fact that it is saturated vapor)

Substituting these values into the formula gives:

ηisentropic = (3514.1 - 2823.2) / (3514.1 - 2816.2)

ηisentropic = 0.8217 or 82.17%

The impedance threshold device (ITD) may improve circulation during active compression-decompression CPR by increasing the negative intrathoracic pressure during chest decompression.

What is the impedance threshold device (ITD)?The impedance threshold device (ITD) is a device that attaches to a patient's endotracheal tube and improves circulation during active compression-decompression cardiopulmonary resuscitation (CPR). This device works by increasing the negative intrathoracic pressure during chest decompression, which increases venous return and blood flow to the heart. The device limits the amount of air entering the lungs during chest recoil, creating an artificial inspiratory resistance that enables a vacuum to be produced.

The ITD was introduced in 1998 and has since become a valuable tool in cardiac arrest management. When used in conjunction with active compression-decompression CPR, the ITD has been shown to increase blood flow and improve survival rates. As a result, many emergency medical services (EMS) providers have begun to include the ITD as part of their standard cardiac arrest treatment protocols.

The result of high efficiencies on a non-constraint machine is increased productivity and improved utilization of resources.

When a non-constraint machine operates at high efficiencies, it has several positive outcomes. Firstly, increased productivity is achieved, as the machine is able to produce output at a faster rate without compromising on quality. This means that more goods or services can be produced within the same timeframe, leading to higher overall production levels.

Secondly, high efficiencies on a non-constraint machine result in improved utilization of resources. The machine can utilize input resources such as raw materials, energy, and labor more efficiently, minimizing waste and maximizing output. This can lead to cost savings and increased profitability for the organization.

Furthermore, high efficiencies can enhance the reliability and consistency of the machine's performance. It reduces the likelihood of breakdowns or disruptions in production, allowing for smoother operations and fewer interruptions.

Section Key Terms

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

Amplifier gain is equal to 10.67.

Explanation:

Voltage gain of an amplifier can be expressed as this equation:

A_v = (V_output) / (V_input)

Where A_v is the gain, V_output is the output voltage, and V_input is the input voltage.

For this we will solve:

A_v = 128 mV / 12 mV

A_v = 10.67

So the amplifier's gain is 10.67.

Answer:

a) The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

b) The change in diameter of the specimen is  - 0.015 mm

Explanation:

Given the data  in the question;

(a) The amount by which this specimen will elongate in the direction of the applied stress.

First we find the area of the cross section of the specimen

A = \(\frac{\pi }{4}\) d²

our given diameter is 20.5 mm so we substitute

A = \(\frac{\pi }{4}\) ( 20.5 mm )²

A = 330.06 mm²

Next, we find the change in length of the specimen using young's modulus formula

E = σ/∈

E = P/A × L/ΔL

ΔL = PL/AE

P is force ( 46300 N), L is length ( 201 mm ), A is area ( 330.06 mm² ) and E is  elastic modulus (60.5 GPa) = 60.5 × 10⁹ N/m² = 60500 N/mm²

so we substitute

ΔL = (46300 N × 201 mm) / ( 330.06 mm² × 60500 N/mm² )

ΔL =  0.466 mm

Therefore, The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

(b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.

Using the following relation for Poisson ratio

μ = -  Δd/d / ΔL/L

given that Poisson's ratio of the metal is 0.33

so we substitute

0.33 = -  Δd/20.5 / 0.466/201

0.33 = -  Δd201 / 20.5 × 0.466

0.33 = - Δd201  / 9.143

0.33 × 9.143 =  - Δd201

3.01719 = -Δd201

Δd = 3.01719 / - 201

Δd  = - 0.015 mm

Therefore, The change in diameter of the specimen is  - 0.015 mm
