The difference between the role of a data steward and the role of a data custodian is as follows:

The role of a data steward involves defining data quality standards, data policies, and data governance processes to ensure the overall integrity, consistency, and accuracy of the data within an organization. Data stewards work closely with business users and data management teams to establish data definitions, classifications, and usage guidelines. They are responsible for monitoring and maintaining the quality of the data throughout its lifecycle.

On the other hand, the role of a data custodian focuses on the technical aspects of data management, such as implementing data storage, backup, and security measures. Data custodians are responsible for the day-to-day management and maintenance of the data infrastructure, ensuring that data is stored securely and is easily accessible to authorized users. They also handle tasks like data migration, archiving, and the execution of data governance policies set by data stewards.

In summary, data stewards are responsible for defining and overseeing data quality standards and policies, while data custodians handle the technical aspects of data management and infrastructure maintenance.

Some reasons buildings move over time are as follows:

1. Foundation Settlement: An explanation for building movement is the natural settling of the foundation due to soil compression or changes in moisture content. Over time, this causes the building to shift or sink unevenly.

2. Soil Erosion: Erosion occurs when soil is washed away due to water movements, such as rain or flooding. This can lead to the building's foundation becoming unstable and the structure moving.

3. Earthquakes: Earthquakes generate seismic waves that can cause buildings to move or even collapse if their structures are not designed to withstand the forces involved.

4. Temperature Changes: Buildings can expand and contract as temperatures fluctuate. Over time, this movement can cause structural stress and cracks in the building materials.

5. Tree Roots: Tree roots can grow and spread, causing pressure on building foundations and leading to movement over time.

6. Poor Construction: If a building is not constructed properly, it may not have the necessary structural support to withstand the forces acting on it, causing movement over time.

7. Ground Movement: Natural ground movements such as landslides, subsidence, or heave can cause the building's foundation to shift, leading to structural movement.

In conclusion, there are various reasons why buildings move over time, including foundation settlement, soil erosion, earthquakes, temperature changes, tree root growth, poor construction, and ground movement. Each of these factors can contribute to the overall stability and integrity of a building.

On estimating roll force and torque during a rolling operation. To estimate the roll force and torque for this rolling operation with given parameters h0 = 0.20-in, hf = 0.15-in, w0 = 10-in, R = 8 in, Mu = 0.25, and an average flow stress of 40 ksi, follow these steps:

1. Calculate the reduction in thickness:
Δh = h0 - hf = 0.20-in - 0.15-in = 0.05-in

2. Determine the true strain:
ε = ln(h0/hf) = ln(0.20-in/0.15-in) = 0.2877

3. Estimate the average flow stress during rolling:
σ_avg = 40 ksi

4. Calculate the contact length between the roll and the material:
L = sqrt(R * Δh) = sqrt(8-in * 0.05-in) = 0.6325-in

5. Estimate the roll force:
F = σ_avg * L * w0 = 40 ksi * 0.6325-in * 10-in ≈ 253 ksi-in

6. Calculate the roll radius (since R is given in inches, convert it to feet for torque calculation):
R_ft = R/12 = 8-in/12 = 0.6667-ft

7. Estimate the torque:
T = Mu * F * R_ft = 0.25 * 253 ksi-in * 0.6667-ft ≈ 42.22 ksi-ft

In summary, the estimated roll force for this rolling operation is approximately 253 ksi-in, and the torque is approximately 42.22 ksi-ft.

Alloys are typically stronger than pure metals because impurity atoms within the metal's crystal structure impose lattice strains on the surrounding atoms which ultimately reduce the mobility of dislocations.

The presence of impurity atoms in an alloy can disrupt the regular arrangement of atoms in the crystal lattice of a pure metal. These disruptions, known as lattice strains or lattice distortions, can hinder the movement of dislocations, which are lines or planes of defects in the crystal lattice that allow for plastic deformation (permanent deformation) of metals. By reducing the mobility of dislocations, the lattice strains introduced by impurity atoms can make it more difficult for the metal to deform, resulting in increased strength and hardness. Additionally, alloying can also lead to the formation of solid solution phases, which are homogenous mixtures of two or more metals at the atomic level. Solid solution strengthening can further contribute to the increased strength of alloys by impeding the movement of dislocations and enhancing the overall mechanical properties of the material.

One advantage of carrying out a number of tasks concurrently is that it can increase productivity and efficiency. When multiple tasks are being worked on simultaneously.

However, a disadvantage of carrying out a number of tasks concurrently is that it can lead to decreased focus and quality of work.

The pressure in the cap end of the cylinder when extended at a constant velocity = ≈ 14,636 psi.

We can calculate the pressure in the cap end of the cylinder when extended at a constant velocity by:

Given:

Cylinder bore diameter = 2 inches

Load weight = 1,615 lbs

Coefficient of friction = 0.13

Slope angle = 28 degrees

Calculate the force of gravity on the load:

Load force = Load weight * acceleration due to gravity

Load force = 1,615 lbs * 32.2 ft/s² (acceleration due to gravity)

Load force = 51,943 lbs

Calculate the frictional force on the load:

Normal force = Load force * cos(slope angle)

Normal force = 51,943 lbs * cos(28 degrees)

Normal force = 46,151 lbs

Frictional force = Coefficient of friction * Normal force

Frictional force = 0.13 * 46,151 lbs

Frictional force = 5,999 lbs

Calculate the net force on the cylinder:

Net force = Load force - Frictional force

Net force = 51,943 lbs - 5,999 lbs

Net force = 45,944 lbs

Calculate the pressure in the cap end of the cylinder:

Cap end area = pi * (Cylinder bore diameter / 2)²

Cap end area = 3.14 * (2 inches / 2)²

Cap end area = 3.14 square inches

Pressure = Net force / Cap end area

Pressure = 45,944 lbs / 3.14 square inches

Pressure = 14,636 psi

Therefore, the pressure in the cap end of the cylinder when extended at a constant velocity = ≈ 14,636 psi.

With a rated 240 V, a 10 kW heating element would unsurprisingly yield approximately 34,121.42 BTU/h.

To determine the power of a 10 kW heating element functioning at a constant 240 V in BTU/h (British Thermal Units per hour), we must initially convert from kilowatts to watts and then use an appropriate conversion factor.

1 kW = 1,000 W

So, 10 kW equates to 10,000 W

To arrive at BTU/h, we can apply the following conversion factor:

1 W = 3.412142 BTU/h

Thus, by multiplying the wattage amount with the conversion rate, we come up with the total BTU/h output:

BTU/h = 10,000 W * 3.412142 BTU/h/W = 34,121.42 BTU/h

We will have to solve for the radius of rotors r = d/2 = 3.2/2 = 1.6m

Find the area of the rotor

A = π * r^2 = π * (1.6)^2 = 8π = 25.13m^2
