The wafer cost $2000 and hold 400 gross die with a yield of 70% (packaging yield is 100%). If packaging and test costs are negligible, how much do you need to charge per chip to have a 60% profit margin? How many chips do you need to sell to obtain a five-fold return on your $16M investment?
Answers
To calculate the cost per chip, we need to consider the total cost and the number of chips produced.you would need to sell 5,600 chips to obtain a five-fold return on your $16M investment.
Total cost = Wafer cost / Yield
= $2000 / 0.7 (taking into account a yield of 70%)
= $2857.14
To achieve a 60% profit margin, the selling price per chip should be calculated as follows:
Selling price per chip = Total cost / (1 - Profit margin)
= $2857.14 / (1 - 0.60)
= $7142.86
To determine the number of chips needed to obtain a five-fold return on the $16M investment, we can divide the investment by the cost per chip:
Number of chips = Investment / Cost per chip
= $16,000,000 / $2857.14
= 5,600

c. every 20 feet
d. every 5 feet
Answers
Option c. every 20 feet
This means that in large pools with outlets more than 5 feet from the end wall, pool inlets should be located every 20 feet. This is important for proper circulation and to prevent stagnant water in certain areas of the pool. In large pools, proper water circulation is essential to maintain cleanliness and ensure even distribution of chemicals. Pool inlets should be placed every 20 feet along the length of the pool to achieve optimal water flow and maintain a healthy swimming environment.
It's important to note that having proper circulation in a pool is crucial for maintaining a healthy and safe swimming environment. Pool inlets are responsible for bringing in fresh water, while outlets help to remove dirty water.

a spring 60 cm long is stretched by 2 cm by the application of the load of 200g. Whag will be the lenght when a load of 500g is applied?
Answers
Considering the situation described and the concept of force, load, and area, the length when a load of 500g is applied is 65cm
What are Force, Load, and Area?Force is a scientific term that is used to describe the influence that can alter the motion of an object.
Generally, force is also known to cause an object with mass to change its velocity, Ti can be either a push or a pull.
Also, Load is a term that is used to describe the force exerted on a surface or body.
While Area is a term that is used to describe the amount of surface a two-dimensional shape can cover.
Therefore, in this case, the springs extend by 2cm when a load of 200g is applied.
Given that ks = mg
Hence, we have k = mg/x
Where we have 500g, we calculate the length from the current details in the question as
k = 0.2*10/0.02
k = 100
Hence, 100x = 0.5*10 x=5cm
Therefore, 5cm + 60cm = 65cm
Hence, in this case, it is concluded that the correct answer is 65cm.

Hello! In this question, we are trying to find the maximum value of shear flow in the web of the wing spar. Note that we are trying to find this with a section that is 1 meter away from the free end of the beam.
__________________________________________________________
Explanation:
In this problem, we know that:
the web has a thickness of 2 mm.Fully effective in resisting direct stressThis information should be kept in mind and can help us solve our problem.
__________________________________________________________
Solve:
Let us begin to solve the problem.
Since we're analyzing the moment in one section, in this case, we can note this as "section 1", we can use this formula to determine the moment in this section:
\(M_{1}=\frac{wl^2}2}\)
Whereas:
Plug in the values into the equation and solve:
\(M_{1}=\frac{15*1^2}2}=7.5\text{kN-m}\)
Now, let us find the moment of inertia of the beam in our 1st section. We'll use the formula:
\(I_{xx}=\frac{BD^3}{12} +2Ah^2\)
Whereas:
B = width (2 mm)D = depth (300 mm)A = area (500 mm²)h = centroid of this section (150 mm)Plug in the values into the equation and solve:
\(I_{xx}=\frac{2(300)^3}{12} +2(500)(150)^2=2.7\times10^7\:\text{mm}^4\)
Now knowing our moment and inertia, we can solve our direct distress in the z direction of our flanges using the following formula:
\(\sigma_{z,U} = -\sigma_{z,L}=\frac{M_{1}}{I_{xx}}y\)
We know:
Plug the values into the equation and solve. (Note that unit conversion was done for M1):
\(\sigma_{z,U} = -\sigma_{z,L}=\frac{7.5\text{kN-m}*(\frac{1000 N}{1kN})(\frac{1000mm}{1m} )}{2.7\times10^7}(150mm)=-41.7\:\text{N/mm}^2\)
Since we now know what our direct distress is, we can find the bending moment resultant with the formula:
\(P_{z,U}=\sigma_{z,U}\times A\)
We know:
\(\sigma_{z,U} = -\sigma_{z,L}=-41.7\:\text{N/mm}^2\)A = 500 mm² (according to our wing spar given in our problem)Plug in the values to our equation and solve:
\(P_{z,U}=-41.7\:\text{N/mm}^2\times 500\:mm^2=-20850\:N\)
Now knowing our bending moment resultant, we can now find our flange load of the web section. Note that our flange load is uniformly distributed. We will use the formula:
\(P_{U}=\sqrt{P_{z,U}^2+P_{y,U}^2}}\)
We know that:
Plug in the values into the equation and solve:
\(P_{U}=\sqrt{(-20850)^2+0^2}}=20850\:N\)
Please note that the answer we calculated above is our tension (T).
Let's now calculate our bending moment resultant using:
\(P_{y,L}=P_{z,L}\times\frac{\delta{y}^2}{\delta_{z}}\)
We know:
\(P_{z,L}=-20850\:N\)\(\delta{y}^2=100\:mm\)\(\delta_{z}=1\:m\)Plug in the values and solve. To make things go faster, I included the unit conversion for our denominator value:
\(P_{y,L}=-20850\:N\times\frac{100\:mm}{(1\:m\times\frac{1000\:mm}{1\:m} )}=-2085\:kN=2085\:kN\)
Please note that the above calculation would be our compression value.
Let's calculate our shear force in the web in our 1st section using a known relationship:
\(S_{y}=-W\times\delta_{z}+P_{y,L}\)
We know:
Plug in our known values and solve:
\(S_{y}=-15\times(1\:m\times\frac{1000\:mm}{1\:m} )+2085=-12915\:N\)
In order to figure out what our shear flow is (note that our shear flow is represented as q), we will use the relationship:
\(q=\frac{S_y}{I_{xx}} [\int_{0}^{s}2(150-s)ds+500\times(\frac{300}{2} )]\)
We know:
\(S_{y}=-12915\:N = 12915\:N\)\(I_{xx}=2.7\times10^7\:mm\)Plugging in the values, we will get:
\(q=\frac{12915}{2.7\times10^7\:mm} [\int_{0}^{s}2(150-s)ds+500\times(\frac{300}{2} )]\)
Simplify the equation:
\(q=4.78\times10^{-4} [\int_{0}^{s}(300-s)ds+75000]\)
Integrate the equation:
\(q=4.78\times10^{-4} [\int_{0}^{s}(300-s)ds+75000]\\\\q=4.78\times10^{-4} ((300s-\frac{2s^2}{2} +[0])+75000)\\\\q=4.78\times10^{-4} ((300s-s^2 )+75000)\)
We now have our equation for the shear flow. We know that the max value of shear flow will happen when s equals 150 mm, so let's plug in the value 150 mm into "s" in our "q" equation and solve:
\(q=4.78\times10^{-4} ((300(150)-150^2 )+75000)=\boxed{46.8\:N/mm}\)
__________________________________________________________
Answer:
The max value of shear flow in the web in the 1st section of the beam is:
\(q=\boxed{46.8\:N/mm}\)

Calculate the maximum length of the specimen before deformation if the maximum allowable elongation is 0.46 mm.
Answers
Answer:
the maximum length of the specimen before deformation is 0.4366 m
Explanation:

Elastic modulus E = 124 GPa = 124 × 10⁹ Nm⁻²
cross-sectional diameter D = 4.2 mm = 4.2 × 10⁻³ m
tensile load F = 1810 N
maximum allowable elongation Δl = 0.46 mm = 0.46 × 10⁻³ m

\(l\) = [ Δl × E × π × D² ] / 4F
so we substitute our values into the formula
\(l\) = [ (0.46 × 10⁻³) × (124 × 10⁹) × π × (4.2 × 10⁻³)² ] / ( 4 × 1810 )
\(l\) = 3161.025289 / 7240
\(l\) = 0.4366 m
Therefore, the maximum length of the specimen before deformation is 0.4366 m

7. Why are products tested at extremes?
Answers
A prototype is a rough model or sample of a system, product, or procedure that is created to test and validate concepts, features, and presumptions.
What is a prototype?It can be used to assess the design, gauge user reaction, and determine whether a notion is workable. Physical or digital prototypes can be made early in the product development cycle to iteratively enhance the design before going into production.
What is the difference between artistic design and engineering design?There are two different ways to approach design: artistic design and engineering design. Whereas engineering design stresses a product's technical viability and usefulness, artistic design places more emphasis on the aesthetics and emotional appeal of a piece of art or product. Whereas engineering design focuses on the function of a design, artistic design frequently emphasizes the aesthetic or emotional impact of a design.

what is the one best field test for estimating the relative density of an uncemented sand deposit and the undrained shear strength of a deposit of saturated clay at the same site?
Answers
The Standard Penetration Test (SPT) is is the one best field test for estimating the relative density of an uncemented sand deposit and the undrained shear strength of a deposit of saturated clay at the same site
What is the Standard Penetration Test?An often utilized field test for determining the approximate density of an uncompacted sand deposit is the Standard Penetration Test (SPT). The process entails inserting a typical sample-collecting tool into the ground with a customary force and gauging the amount of force needed to reach a regular depth with the tool.
The vane shear test is a widely used field test for approximating the undrained shear strength of a saturated clay deposit. This process entails the placement of a blade into the ground and consistently turning it while observing the force necessary to turn the blade.

Merchandise without an expiration date like electronics, tools and home goods typically have a longer
Answers
Answer:
Shelf life.
Explanation:
In Business, an inventory is a term used to describe a list of finished goods, goods still in the production line and raw materials that would be used for the manufacturing of more goods in a bid to meet the unending consumer demands.
Simply stated, an inventory can be classified into three (3) main categories; finished goods, work in progress, and raw materials.
An inventory is recorded as a current asset on the balance sheet because it's primarily the most important source of revenue for a business entity.
Also, the three (3) main cost concept associated with an inventory are;
1. First In First Out (FIFO).
2. Last In First Out (LIFO).
3. Weighted average cost.
Shelf life can be defined as a measure of the length of time that a particular product could be kept or stored without it getting bad or becoming unsuitable for use by the consumers. Thus, the shelf life of a product is largely dependent on its expiration date.
Hence, merchandise without an expiration date like electronics, tools and home goods typically have a longer shelf life.
The monthly output of a certain product is Q(x)=2500x 5/2
where x is the capital investment in millions of dollars. Find dQ/dx, which can be used to estimate the effect on the output if an additional capital investment of $1 million is made. dQ/dx=
Answers
The monthly output of a certain product can be given by the function
\(`Q(x) = 2500x^(5/2)`\)
where x is the capital investment in millions of dollars.
differentiate the function Q(x) with respect to x.
\(dQ/dx = d/dx(2500x^(5/2))\)
Using the power rule of differentiation, we have:
\(dQ/dx = (5/2) * 2500 * x^(5/2 - 1)dQ/dx
= 6250x^(3/2) `dQ/dx
= 6250x^(3/2)`\)
which gives us the effect on the output if an additional capital investment of $1 million is made.
Note: To estimate the effect on the output if an additional capital investment of $1 million is made, we substitute x with x+1 in the expression for `dQ/dx`. This gives us the new output and the increase in output due to the additional investment.

What do you understand by material engineering?
Math, physics, and chemistry are the instruments that materials engineers employ to investigate, comprehend, and regulate the behavior of materials. We use that information to create new materials, determine the best ways to use already-existing materials and processing methods, and provide reasons why some materials failed.
What do you understand by Induction motor?
An induction motor, also known as an asynchronous motor, is an AC electric motor in which the magnetic field of the stator winding is used to electromagnetically induct the electric current into the rotor necessary to produce torque. Therefore, it is possible to construct an induction motor without electrical connections to the rotor.
A structure, device, or system that is created, produced, or used by manipulating atoms and molecules at the nanoscale, or having one or more dimensions of the order of 100 nanometers (100 millionth of a millimeter) or less, is referred to as nanotechnology.
The method of producing an object layer by layer is known as additive manufacturing. It is the reverse of subtractive manufacturing, which involves removing small amounts of a solid block of material at a time until the finished item is produced.
For commercial and industrial pumping applications, three-phase alternating current (AC) induction motors are more typical than single-phase motors. Among the causes are: A three-phase motor's individual phase current is less than 60% of that of a comparable single-phase motor.
A pneumatic device known as an air compressor transforms power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air. An air compressor raises the pressure in a storage tank by using one of several techniques to push more and more air into the container.
