No. of transistors = \($4.1524 \times 10^{10}$\) transistors

Explanation:

Given that:

N = \($1920 \times 10^{0.163(Y-1980)}$\)

Y = 2025

N = \($1920 \times 10^{0.163(2025-1980)}$\)

N = \($4.1524 \times 10^{10}$\) transistors

Now at Y = 1980

Number of transistors N = 1920

Therefore,

\($1000 = 10^{0.163(Y-1980)}$\)

\($\log_{10} 1000=0.163(Y-1980)$\)

\($\frac{3}{0.163}=Y-1980$\)

18 ≅ 18.4 = Y - 1980

Y = 1980 + 18

   = 1998

So, to increase multiples of 1000 transistors. it takes 18 years.

Answer:

See explanation below

Explanation:

Hypo-eutectoid steel has less than 0,8% of C in its composition.

It is composed by pearlite and α-ferrite, whereas Hyper-eutectoid steel has between 0.8% and 2% of C, composed by pearlite and cementite.

Ferrite has a higher tensile strength than cementite but cementite is harder.

Considering that hypoeutectoid steel contains ferrite at grain boundaries and pearlite inside grains whereas hypereutectoid steel contains a higher amount of cementite, the following properties are obtainable:

Hypo-eutectoid steel has higher yield strength than Hyper-eutectoid steel

Hypo-eutectoid steel is more ductile than Hyper-eutectoid steel

Hyper-eutectoid steel is harder than Hyper-eutectoid steel

Hypo-eutectoid steel has more tensile strength than Hyper-eutectoid steel.

When making a knife or axe blade, I would choose Hyper-eutectoid steel alloy because

1. It is harder

2. It has low cost

3. It is lighter

When making a die to press powders or stamp a softer metals, I will choose hypo-eutectoid steel alloy because

1. It is ductile

2. It has high tensile strength

3. It is durable

Answer:

(a)

Steels having carbon within 0.02% – 0.8% which consist of ferrite and pearlite are known as hypoeutectoid steel.

Steels having greater than 0.8% carbon but less than 2.0% are known as hypereutectoid steel.

(b)

The proeutectoid ferrite formed at a range of temperatures from austenite in the austenite+ferrite region above 726°C. The eutectoid ferrite formed during the eutectoid transformation as it cools below 726°C. It is a part of the pearlite microconstiutents . Note that both hypereutectoid and hypoeutectoid steels have proeutectoid phases, while in eutectoid steel, no proeutectoid phase is present.

Proeutectoid signifies is a phase that forms (on cooling) before the eutectoid austenite decomposes. It has a parallel with primary solids in that it is the first phase to crystallize out of the austenite phase. If the steel is hypoeutectoid it will produce proeutectoid ferrite and if it is hypereutectoid it will produce proeutectoid cementite.  The carbon concentration for both ferrites is 0.022 wt% C.

(c)

(i) Yield strength: The hypoeutectoid steel have good yield strength and hypereutectoid steels have little higher yield strengh.

(ii) Ductility: The hypoeutectoid steel is more ductile and the ductility has decreased by a factor of three for the eutectoid alloy. In hypereutectoid alloys the additional, brittle cementite on the pearlite grain boundaries further decreases the ductility of the alloy. The proeutectoid cementite restricts plastic deformation to the ferrite lamellae in the pearlite.

(iii) Hardness:  hypoeutectoid steels are softer and hypereutectoid steel contains low strength cementite at grain boundary region which makes it harder than hypoeutectoids.

(iv) Tensile strength: Grain boundary regions of hypereutectoid steel are high energy regions prone to cracking because of cementite in the grain boundaries, its tensile strength decreases drastically even though pearlite is present. Hypoeutectoid steel contains ferrite at grain boundaries and pearlite inside grains, so grain boundaries being the high energy state region, it has a higher tensile strength.

(d)

I would recommend hypereutectoid steel alloy to make a knife or ax blade

1- Hardness is required at the surface of the blades.

2- Ductility is not needed for such application.

3- Due to constant impact, the material will not easily yield to stress.

(e)

I would choose a hypoeutectoid steel alloy to make a steel that was easy to machine.

1- hypoeutectoid steel alloys have high machinability, hence better productivity

2- It will be used on softer metals, hence its fitness for the application

3- Certain amount of ductility is required which hypoeutectoid steel alloys possess.

As a local hardware store employee, I have concerns about the long-term consequences and risks of a gene drive for eliminating West Nile Virus.

Participant: A local hardware store employee

Post:

As a local hardware store employee, I have a vested interest in the well-being of the Phoenix community. I understand that the scientists from ASU are proposing the development of a gene drive to eliminate West Nile Virus in our area, and I believe it's crucial to have an open discussion about this research vision.

Firstly, I want to emphasize that I am not an expert in genetics or public health. However, I do have concerns and questions regarding the potential implementation of a gene drive for such a purpose.

My main concern revolves around the long-term consequences and potential risks associated with altering the genetic makeup of organisms, even if it is for a positive outcome like eliminating West Nile Virus. While the eradication of this disease is undoubtedly a worthy goal, we must ensure that the benefits outweigh any unintended negative effects.

Before I can fully support or oppose this research, I would like to better understand the safeguards that would be put in place to prevent any unintended ecological disruptions. What are the contingency plans if the gene drive were to have unintended consequences on non-target species? Are there measures in place to address potential resistance to the gene drive in the West Nile Virus-carrying mosquitoes? These are critical questions that must be answered to assess the feasibility and safety of this project.

Additionally, it would be crucial to involve a diverse range of stakeholders in the decision-making process. Engaging with experts in genetics, public health officials, and environmentalists, along with community members, will help ensure that all perspectives are taken into account. Transparency and inclusivity are key to fostering trust and ensuring that the decision ultimately made serves the best interests of our community.

In conclusion, while I recognize the importance of addressing the issue of West Nile Virus, I approach the proposal for a gene drive with caution. My starting position is one of skepticism and the need for further information. I believe a comprehensive risk assessment, robust stakeholder engagement, and a thorough examination of potential unintended consequences are necessary before making a final determination on supporting or opposing the project.

There are 21 maximum cyclic tensile stress that the part can experience such that it survives at least 1 million cycles

What is cyclic tensile stress?

The repeated occurrence and redistribution of forces acting on a material is known as cyclic stress. Periodic or consistent cyclic stress conditions enhance the material's wear and tear, which accelerates material degradation and failure.

The stress at which a force causes a material to extend before breaking is known as tensile strength. The breaking strength under tension of an axially loaded material is given by the equation s=P/a, where s is the breaking strength, P is the breaking force, and an is the cross sectional area. For beams, s=M/z, where M is the bending moment that might cause the beam to fail at the extreme fibre in tension, and z is the section modulus of the beam. S is the stress at the extreme fibre in tension. The type of material, the cross-sectional area, and in the case of beams, the section modulus, all affect the tensile strength.

Thus we can say maximum cyclic tensile stress needed is 21 Mpa
