Answer:

Assume a value of 0.22 for the strain-hardening exponent, n.

Explanation:

The annual quantity of welded assemblies that would have to be produced to reach the break-even point for the two methods is approximately 15,983.

To determine the break-even point between the manual arc welding cell and the robotic cell, we need to calculate the total costs for each method and then equate them.

For the manual arc welding cell:

Labor cost per hour = (welder's hourly rate x arc-on time) + (fitter's hourly rate x fitter's participation in the cycle) = ($30 x 0.25) + ($25 x 0.3) = $11.25

Labor cost per welded assembly = labor cost per hour x cycle time per assembly / 60 = $11.25 x 15.4 / 60 = $2.89

Overhead cost per welded assembly = (labor cost per hour x (1 - arc-on time - fitter's participation in the cycle)) x cycle time per assembly / 60 = ($30 x 0.45) x 15.4 / 60 = $4.68

Total cost per welded assembly = labor cost per welded assembly + overhead cost per welded assembly = $2.89 + $4.68 = $7.57

Total cost per hour = total cost per welded assembly x production rate = $7.57 x 8 = $60.56

Total cost per year = total cost per hour x hours of operation per year = $60.56 x 2,000 = $121,120

For the robotic arc welding cell:

Labor cost per hour = fitter's hourly rate x fitter's participation in the cycle = $25 x 0.62 = $15.50

Labor cost per welded assembly = labor cost per hour x cycle time per assembly / 60 = $15.50 x 15.4 / 60 = $3.97

Overhead cost per welded assembly = power and utility cost per hour + annual maintenance cost / production rate = $3.80 + $3,500 / (8 x 2,000) = $3.80 + $0.22 = $4.02

Total cost per welded assembly = labor cost per welded assembly + overhead cost per welded assembly + (installed cost / (production rate x service life)) = $3.97 + $4.02 + ($158,000 / (8 x 3)) = $3.97 + $4.02 + $6,208.33 = $14.19

Total cost per hour = total cost per welded assembly x production rate = $14.19 x 8 = $113.52

Total cost per year = total cost per hour x hours of operation per year = $113.52 x 2,000 = $227,040

To find the break-even point, we set the total cost of the manual arc welding cell equal to the total cost of the robotic arc welding cell and solve for the annual quantity of welded assemblies:

$121,120 + x($7.57) = $227,040 + x($14.19)

$7.57x - $14.19x = $227,040 - $121,120

$-6.62x = $105,920

x = $105,920 / $6.62

x = 15,982.7

Therefore, the annual quantity of welded assemblies that would have to be produced to reach the break-even point for the two methods is approximately 15,983.

According to James Marcia, Maida is exhibiting identity foreclosure. She has made a commitment to a particular identity without exploring other options.

Yes, according to James Marcia's theory of identity formation, Maida's actions and experiences indicate that she is in the stage of identity foreclosure. This means that she has made a commitment to a particular identity, in this case, becoming a doctor, without fully exploring other options or undergoing a crisis of identity. Maida's early exposure to medical equipment and her parents' expectations of her becoming a doctor suggests that her sense of self and career aspirations were influenced by external factors, rather than internal exploration and self-discovery.

It is important to note that identity foreclosure is not necessarily a negative outcome, and many individuals may have a clear and stable sense of self without going through a crisis of identity. However, it is beneficial for individuals to have the opportunity to explore their options and interests in order to make informed decisions about their lives and careers.

Answer:

the answer should be about 33.56fts

The length of the hypotenuse will be 33.55 feet in the given triangle.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

The triangle given in the question is a right triangle.

In a triangle side A has a length of 18.5 ft and side B has a length of 28 ft

A right triangle is represented as a triangle in which one angle is a right angle or two sides are perpendicular.

To determine the length of the hypotenuse.

According to Pythagoras's theorem,

a² + b² = c²

Here a = 18.5 and b = 28

The length of the hypotenuse is c.

(18.5)² + (28)² =  c²

342.25 + 784 = c²

c² = 1126.25

c = 33.55

Therefore, the length of the hypotenuse will be 33.55 feet.

The automobile initially accelerates for 5 seconds. As a result, the velocity-time graph initially slopes and then maintains a constant speed.

Your understanding of velocity and its scientific definition are probably similar. You are aware that a big displacement over a short period of time corresponds to a large velocity, and that velocity is measured in terms of the speed of objects in terms of miles an hour or kilometres per hour. The shift in position multiplied by the distance travelled is how average velocity is calculated. Velocity and speed describe how quickly or slowly a moving object moves. We frequently encounter circumstances when we must determine which of two or more moving objects is going faster. If the two are travelling on the same route in the same direction, it is simple to determine which is quicker.

D) AND gate.

Explanation:

Given that:

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print

These conditions are:

1. The printer's electronic circuits must be energized.

2. Paper must be loaded and ready to advance.

3. The printer must be "on line" with the microprocessor.

Now; if these conditions are met  the logic gate produces a HIGH output indicating readiness to print.

The objective here is to determine the basic logic gate used in this circuit.

Now;

For NOR gate;

NOR gate gives HIGH only when all the inputs are low. but the question states it that "a HIGH is generated and applied to a 3-input logic gate". This already falsify NOR gate to be the right answer.

For NOT gate.

NOT gate operates with only one input and one output device but here; we are dealing with 3-input logic gate.

Similarly, OR gate gives output as a high if any one of the input signals is high but we need "a HIGH that is generated and applied to a 3-input logic gate".

Finally, AND gate output is HIGH only when all the input signal is HIGH and vice versa, i.e AND gate output is LOW only when all the input signal is LOW. So AND gate satisfies the given criteria that; all the three conditions must be true for the final signal to be HIGH.

Given :

Mass of gasoline , m = 50 kg .

Length of tank , l = 0.9 m.

Breadth of tank , b = 0.5 m .

Relative density of gasoline , R.D = 0.75 .

Density of water , \(\rho_{water}=1000\ kg/m^3\) .

To Find :

The depth of tank .

Solution :

We know ,

\(R.D=\dfrac{\rho_{gasoline}}{\rho_{water}}\\\\\rho_{gasoline}=0.75\times 1000 \ kg/m^3\\\\\rho_{gasoline}=750\ kg/m^3\)

Now , volume of gasoline is :

\(V=\dfrac{m}{\rho_{gasoline}}\\\\V=\dfrac{50}{750}\ m^3\\\\V=\dfrac{1}{15}\ m^3\)

Since , the tank is rectangular , volume is given by :

\(V=l\times b\times h\\\\h=\dfrac{V}{l \times b}\\\\h=\dfrac{1}{15\times 0.9\times 0.5}\ m\\\\h=0.148\ m=14.8\ cm\)

Therefore , the answer in centimetres is 14.8 cm .

Hence , this is the required solution .

The ratio of the secondary to primary turns of the transformer be 50:1 and  even if the transformer is connected backward, the voltage output would still be 12 kV.

To determine the ratio of secondary to primary turns of the transformer required to operate a neon sign from a 240 V line, we can use the turns ratio formula:

Turns ratio = Secondary voltage / Primary voltage

In this case, the secondary voltage is 12 kV (12,000 V), and the primary voltage is 240 V.

Turns ratio = 12,000 V / 240 V

Turns ratio = 50Therefore, the ratio of secondary to primary turns of the transformer should be 50:1.

b) If the transformer were connected backward, the voltage output would depend on the turns ratio. In this case, the turns ratio is 50:1, so if the primary voltage is 240 V, the voltage output would be:

Voltage output = Turns ratio × Primary voltage

Voltage output = 50 × 240 V

Voltage output = 12,000 V or 12 kV

Hence, even if the transformer is connected backward, the voltage output would still be 12 kV.
