Answer: the surface shear stress at x =1m from the leading edge of the plate is 4.1973 N/m²

Explanation:

Given that;

density s = 1.16 kg/m³

velocity = u = 50 m/s

kinetic viscosity r = 15.89 × 10⁻⁶ m²/s

xL = 1m from the leading edge of the plate

Now Reynold number (Rex)

Rex = UxL / r

Rex = (50 m/s × 1m ) / 15.89 × 10⁻⁶ m²/s

Rex = 3146633.1025

since Rex is greater than 5×10⁵ { Turbulent flow }

so Local skin friction coefficient

⇒ Cfx = 0.0577 / (Rex)^1/5

Cfx = 0.0577 / (3146633.1025)^1/5

Cfx = 0.0028947

Now Shear stress (y)

y = Cfx × 1/2 × su²

y = 0.0028947 × 1/2 × 1.16 × (50)²

y = 4.1973 N/m²

∴ the surface shear stress at x =1m from the leading edge of the plate is 4.1973 N/m²

Assuming that cell B5 contains the sales amount for the first salesperson, the IFS function to determine the commission rate in cell C5 is:

=IFS(B5>35000, 0.05, B5>25000, 0.04, B5>0, 0.02)

This formula checks the sales amount in B5 against each threshold amount in descending order (starting with $35,000), and returns the corresponding bonus rate if the sales amount is greater than that threshold. If the sales amount is less than or equal to zero, it returns a bonus rate of 0%.

To fill the formula down through cell C8, select cell C5 and drag the fill handle down to cell C8. This will copy the formula to the other cells in the group, adjusting the cell references as needed.

Explanation:

The formula for critical stress is

\(\sigma_c=\frac{K}{Y\sqrt{\pi a} }\)

\(\sigma_c =\texttt{critical stress}\)

K is the plane strain fracture toughness

Y is dimensionless parameters

We are to Determine the Critical stress

Now replacing the critical stress with 54.8

a with 0.2mm = 0.2 x 10⁻³

Y with 1

\(\sigma_c=\frac{54.8}{1\sqrt{\pi \times 0.2\times10^{-3}} } \\\\=\frac{54.8}{\sqrt{6.283\times10^{-4}} } \\\\=\frac{54.8}{0.025} \\\\=2186.20Mpa\)

The fracture will not occur because this material can handle a stress of 2186.20Mpa  before fracture. it is obvious that is greater than 2023Mpa

Therefore, the specimen does not failure for surface crack of 0.2mm

Given the comparison-based sorting algorithm, we need to sort n file objects on an old and unreliable computer. Whenever a comparison operation x ≤ y on two file objects takes place, there is an independent chance of 1/2 that the computer will return the value −1 instead of the correct result of 1 for true and 0 for false.

For every other type of operation including comparisons that do not involve the file objects you are sorting, the computer performs them correctly. The solution algorithm involves the introduction of randomisation in the sorting algorithm. This algorithm is known as Randomised Quicksort. The quicksort algorithm is used to partition an array A, sort its two partitions recursively, and then merge the partitions.

The algorithm selects a pivot element in each partition to split the array. The pivot splits the array such that the elements in its left are less than or equal to the pivot and those on its right are greater than or equal to the pivot. Then, we sort the two partitions recursively.

Lastly, we merge the partitions. The following is the efficient algorithm that can sort n file objects on an unreliable computer correctly: Algorithm to sort the file objects on an unreliable computer Step 1: Divide and Conquer. We first choose a pivot randomly from the n objects.

The formula for axial compressive stress isσa = F/Awhere,σa is axial compressive stress F is force A is cross-sectional area.

How to find the axial compressive stress? A 1/2 - 0.5 lead screw's compressive force is 14 lbf. The formula for the area of a screw is A = πd²/4Where A is the cross-sectional area and d is the screw's diameter. Now, d = 1/2 - 0.5 = 0To find the cross-sectional area of the screw,

we will use the formula A = πd²/4 = π(0)²/4 = 0 As a result, we must consider the pitch of the screw to be the length we're compressing since the screw's diameter is negligible. The pitch of the screw is 0.5 inches. So, F = 14 lbfA = pitch = 0.5 in = 0.0417 ftσa = F/A = 14 lbf/0.0417 ft = 335.7 psithe axial compressive stress in psi is 335.7.

To make a constructor public, you simply need to add the "public" keyword before the constructor. This allows the constructor to be accessible from any part of your program. Option A is the correct choice for making a constructor public.

To make a constructor public, there are a few things that need to be considered. A constructor is a special method that is used to initialize objects when they are created. By default, constructors are public, which means they can be accessed from anywhere in the program. If you want to make a constructor public, you can simply add the keyword "public" before it. This will allow other classes to create objects of your class and access its constructor. However, there are some misconceptions regarding the process of making a constructor public. Firstly, making a constructor public does not require you to make each variable public. Variables can still be private or protected, depending on your needs. Secondly, having a private constructor is not a requirement for making a constructor public. A private constructor is used when you want to prevent the creation of objects from outside the class.

In conclusion, to make a constructor public, you only need to add the keyword "public" before it. You do not need to make each variable public or have a private constructor. Remember that constructors are essential for initializing objects, and making them public allows other classes to create and use objects of your class.

A sinusoidal current is an alternating current (AC) that varies in magnitude and direction over time, following a sinusoidal waveform. It is called "sinusoidal" because its shape resembles a sine wave, which is a smooth and continuous curve that oscillates between positive and negative values.

Sinusoidal currents are commonly used in electrical power systems to transfer energy from power plants to homes and businesses. They have several advantages over direct current (DC) systems, including the ability to be easily transformed to different voltage levels using transformers, and the ability to be transmitted over long distances with minimal power loss.

The critical path is the longest path through a project network diagram, which includes all the activities that are critical to the completion of the project. In order to calculate the critical path, you will need to follow these steps:

Identify all the activities that need to be completed for the project.

Determine the duration of each activity. This can be estimated based on past experience or expert opinion, or by conducting time studies.

Create a network diagram that shows the sequence of activities and their dependencies. This can be done using software such as Microsoft Project or by drawing a diagram manually.

Identify the earliest start and finish times for each activity, based on the dependencies and durations.

Identify the latest start and finish times for each activity, based on the project deadline.

Calculate the total float or slack for each activity, which is the amount of time that an activity can be delayed without affecting the overall project completion date.

Identify the critical path, which is the longest path through the project network diagram that has zero total float or slack. This means that any delay in one of the activities on the critical path will cause a delay in the overall project completion date.

Once you have identified the critical path, you can focus your attention on managing and monitoring the activities on that path to ensure that the project stays on schedule.

Answer:

A conductor

Explanation:

Answer: False

Explanation:

The given statement "In some expensive cookware, the pot is made of copper but the handle is made of stainless steel" is True because, in some expensive cookware, the pot is made of copper while the handle is made of stainless steel.

Copper is an excellent conductor of heat and provides even heat distribution, making it a popular choice for cookware. However, copper is a reactive metal and can react with acidic foods, causing a metallic taste and discoloration. To avoid this, cookware manufacturers use a non-reactive material such as stainless steel for the handles, which is durable and does not react with food.

Stainless steel also provides a good grip and stays cool to the touch even when the pot is heated. The combination of copper and stainless steel in cookware provides the best of both worlds – excellent heat distribution and a durable, non-reactive handle. This type of cookware is often more expensive due to the use of high-quality materials and craftsmanship.

Answer:

according to Miners method the new endurance limit S\(_e\)" is 45 kpsi

Explanation:

Given the data in the question;

the amplitude stress σₐ = 35 kpsi

the mean stress for 12(10³) cycles σ\(_m\) = 30 kpsi

the ultimate tensile stress S\(_{ut\) = 85 kpsi

endurance limit of S\(_e\) = 45 kpsi

so, we calculate the reversing stress for Gerber criteria

σ\(_{rev\) = σₐ / [ 1 - ( σ\(_m\)/S\(_{ut\))²

we substitute

σ\(_{rev\) = 35 / [ 1 - ( 30/85)²]

σ\(_{rev\) = 35 / [ 1 - 0.124567]

σ\(_{rev\) = 35 / 0.875433

σ\(_{rev\) = 39.98 kpsi

Using Miners Method;

the reversing stress ( 39.98 kpsi ) is less than endurance limit ( 45 kpsi )

σ\(_{rev\)  < S\(_e\)

According to Miners method, if reversing stress is less than endurance limit, then the endurance limit has not reduced and new endurance limit remains the same.

Hence, according to Miners method the new endurance limit S\(_e\)" is 45 kpsi
