If the specific surface energy for magnesium oxide is 1.0 J/m2 and its modulus of elasticity is (225 GPa), compute the critical stress required for the propagation of an internal crack of length 0.7 mm.
Answers
Answer:critical stress= 20.23 MPa
Explanation:
Since there was an internal crack, we will divide the length of the internal crack by 2
Length of internal crack, a = 0.7mm,
Half length = 0.7mm/2= 0.35mm changing to meters becomes
0.35/ 1000= 0.35 x 10 ^-3m
The formulae for critical stress is calculated using
σC = (2Eγs /πa) ¹/₂
σC = critical stress=?
Given
E= Modulus of Elasticity= 225GPa =225 x 10 ^ 9 N/m²
γs= Specific surface energy = 1.0 J/m2 = 1.0 N/m
a= Half Length of crack=0.35 x 10 ^-3m
σC= (2 x 225 x 10 ^ 9 N/m² x 1.0 N/m /π x 0.35 x 10 ^-3m)¹/₂
=(4.5 x 10^11/π x 0.35 x 10 ^-3)¹/₂
=(4.0920 x10 ^14)¹/₂
σC=20.23 x10^6 N/m² = 20.23 MPa
Which of the following is roofing that consists of layers of overlapping roof felt with each layer set in a mopping of hot tar of asphalt?
a. Corrugated roofing b. Liquid roofing c. Tile roofing d. Built-up roofing
Answers
The correct answer is d. Built-up roofing (BUR),It consists of layers of overlapping roof felt with each layer set in a mopping of hot tar of asphalt.
Built-up roofing is a durable and reliable option containing asphalt roofs. It is a traditional roofing system that has been used for many decades. BUR consists of multiple layers of roof felt or roofing fabric, typically made of fiberglass or organic materials.
These layers are set in a mopping of hot tar or asphalt, which acts as an adhesive and creates a strong bond between the layers.The process of installing a BUR system involves alternating layers of roofing felt and hot tar.
Each layer is carefully mopped onto the roof surface, ensuring proper overlap and coverage. This layering process enhances the waterproofing capabilities of the roof, providing excellent protection against water infiltration.
The final layer of a BUR system is often topped with a layer of gravel or other surfacing material. This surfacing layer serves multiple purposes. It protects the underlying layers from UV radiation, helps to distribute the weight of foot traffic or equipment, and provides additional fire resistance.
One of the key advantages of built-up roofing is its longevity. When properly installed and maintained, a BUR system can last for several decades. It is also resistant to fire, making it a popular choice for commercial and industrial buildings.
In summary, built-up roofing is a layered roofing system that utilizes roof felt and hot tar to create a durable, watertight, and fire-resistant roof. Its proven track record and longevity make it a reliable option for flat or low-slope roofs.

A simply supported beam (E 512 GPa) carries a uniformly distributed load q 5125 N/m, and a point load P 5 200 N at mid-span. The beam has a rectangular cross section (b 5 75 mm, h 5 200 mm) and a length of 3.6 m. Calculate the maximum deflection of the beam
Answers
Answer:
\(\mathbf{\Delta_{max}=0.78 \ mm}\)
Explanation:
From the given information;
A simply supported beam (E = 12 GPa)
load q = 125 N/m
point load P = 200 N
the rectangular cross section
b = 75 mm
h = 200 mm
length = 3.6 m
The objective is to calculate the maximum deflection of the beam;
Using the formula;
\(I = \dfrac{1}{E}*bh^3\) about the z-axis that goes through the central
\(I = \dfrac{1}{12}*(75 \ mm)*(200 \ mm)^3\)
\(I = 5*10^7 \ mm^4\)
The length L = 3.6 m = 3600 mm
The maximum deflection of the beam can be calculated by using the formula:
\(\Delta _{max} = \dfrac{5}{384}* \dfrac{qL^4}{EI}+\dfrac{PL^3}{48EI}\)
\(\Delta _{max} = \dfrac{1}{12*10^3 \frac{N}{mm^2}*5*10^7 \ mm^4 }[ \dfrac{5*\frac{125 \ N}{100 \ mm}*3600 \ mm^4}{384}+\dfrac{200*(3600 \ mm )^3}{48}]\)

Ethylene oxide is produced by the catalytic oxidation of ethylene: 2C2H4 + O2 -> 2C2H4O
while an undesired competing reaction is the combustion of ethylene: C2H4 + 3O2 -> 2CO2 + 2H2O
The immediate feed to the reactor (not the fresh feed) contains 3 moles of ethylene per mole of oxygen. The single-pass conversion of ethylene is 20%, and for every 100 moles of ethylene consumed in the reactor, 90 moles of ethylene oxide emerge in the reactor products. All components are separated through subsequent processes. Ethylene and oxygen are recycled to the reactor, ethylene oxide is sold as a product, while carbon dioxide and water are sent for use elsewhere in the plant.
Determine all flow rates assuming ethylene oxide must be produced at a rate of 2,000 pounds per hour.
(Use a chart method if you know that way)
Answers
The flow rates of the different components are :Flow rate of ethylene = 0.033 lb/hr (approx)Flow rate of oxygen = 0.038 lb/hr (approx)Flow rate of ethylene oxide = 2000 lb/hrFlow rate of CO2 and H2O = 0.013 lb/hr (approx).
Given dataImmediate feed to the reactor contains 3 moles of ethylene per mole of oxygenSingle-pass conversion of ethylene is 20%, and for every 100 moles of ethylene consumed in the reactor, 90 moles of ethylene oxide emerge in the reactor products.Flow rate of ethylene oxide = 2000 lb/hrSteps to determine all flow rates:We have to start by determining the number of moles of ethylene oxide to be produced per hour.Conversion of ethylene in a single pass = 20%Thus, the number of moles of ethylene converted per hour = (20/100) × 3 = 0.6 mol/hr.
Therefore, the number of moles of ethylene oxide produced per hour = (0.6 mol/hr) × (90/100) = 0.54 mol/hrFor every mole of ethylene oxide produced, 2 moles of ethylene are consumed and 1 mole of oxygen is consumed.Thus, the total number of moles of ethylene consumed per hour = (2/1) × 0.54 = 1.08 mol/hrThe number of moles of oxygen consumed per hour = 0.54 mol/hrLet us now convert these moles into mass flow rates using the molar mass of each component.
Flow rate of ethylene = (1.08 mol/hr) × (28.05 g/mol) × (1 lb/454 g) = 0.066 lb/hr (approx)Flow rate of oxygen = (0.54 mol/hr) × (32 g/mol) × (1 lb/454 g) = 0.021 lb/hr (approx)Flow rate of ethylene oxide = 2000 lb/hrFlow rate of CO2 and H2O = Sum of the flow rates of ethylene and oxygen - flow rate of ethylene oxide= (0.066 + 0.021) - (2000/454) = -4.4 lb/hrThis negative flow rate of CO2 and H2O indicates that there is an error in our calculations. We made an assumption that for every mole of ethylene oxide produced, 2 moles of ethylene are consumed.
However, this is not true, as the stoichiometry of the reaction shows that for every mole of ethylene oxide produced, 1 mole of oxygen is consumed. Therefore, we need to recalculate the flow rates using this stoichiometry.Flow rate of ethylene = (0.54 mol/hr) × (28.05 g/mol) × (1 lb/454 g) = 0.033 lb/hr (approx)Flow rate of oxygen = (0.54 mol/hr) × (32 g/mol) × (1 lb/454 g) = 0.038 lb/hr (approx)Flow rate of ethylene oxide = 2000 lb/hrFlow rate of CO2 and H2O = Sum of the flow rates of ethylene and oxygen - flow rate of ethylene oxide= (0.033 + 0.038) - (2000/454) = 0.013 lb/hr (approx).

Answers
Answer:
Hello your question is incomplete attached below is the missing part of the question
answer ;
voltage drop in the Vcd branch = 30 V
Voltage drop in the middle branch = 40v - 30v = 10 volts
voltage drop in AB = 60 + ( -600 * 0.05 ) = 60 - 30 = 30 volts
Explanation:
Determine voltage drop from top terminal to bottom terminal ( Vab ) in the right hand branch and Vcd in left hand branch
40v and 50mA are in series hence; Ix = 50mA
also Vcd = 30V
CD is parallel to AB hence; Vcd = Vab = 30 V
Vab = ∝*Ix + 60 v
30v = ∝ ( 50mA ) + 60
therefore ∝ = -600
voltage drop in the Vcd branch = 30 V
Voltage drop in the middle branch = 40v - 30v = 10 volts
voltage drop in AB = 60 + ( -600 * 0.05 ) = 60 - 30 = 30 volts

Answers
A) If climbing at VMO, it is possible to exceed MMO.VMO and MMO are two different limits that aircraft have to operate within to ensure their safety.
VMO is the maximum indicated airspeed at which the aircraft can be flown without risking damage to the structure due to excessive aerodynamic loads. On the other hand, MMO is the maximum Mach number at which the aircraft can be flown without risking the onset of compressibility effects, such as shock waves and control surface flutter.During a climb, the airspeed decreases as the aircraft gains altitude, while the Mach number increases due to the decreasing air density. Therefore, if an aircraft is climbing at VMO, it is possible to exceed MMO since the Mach number is increasing while the airspeed is decreasing.

Need help fast 50 points Project: Creating a Morphological Matrix
Assignment Directions
A systematic way to view common functionality of an object's structure and components is through a morphological matrix. You are going to utilize this method to analyze a common household device (from the list below or your own idea). First, create the left-hand column by deciding on the parameters that allow the object to function normally. For example, a pencil sharpener has a blade and a housing unit to support the system. Use the parameters to describe the system. If the pencil sharpener is hand operated, list the parameter of hand turning (either the pencil itself in a small unit or a handle in a wall-mounted device). The parameter column can include specific structures in the device, power sources, or any other information you learned in the lesson. The right-hand columns will include the current methods used by the device to complete the parameter, as well as any other options that would satisfy the parameter. You must create at least two other options for each parameter.
While the matrix provides valuable information for an engineer, it is typically more technological than a client or decision team needs. Therefore, you will also need to complete a one- or two-page analysis of the device, including the current parameter solutions and any recommended alterations to a design. Each recommendation must be supported by information in the morphological matrix.
Here are some ideas of household devices that you can analyze:

The fundamental difference between effective and less effective matrix organizations is whether the tension between different perspectives is creative or destructive. While various processes, systems and tools can help, what matters most is what top leadership says and does and how that flows through the organization in shared targets, clear accountabilities, live team interactions and team-building transparency and behaviors.
Getting matrix management right is linked inextricably to an organization’s culture - the only sustainable competitive advantage. Key components of a culture can be grouped into behaviors, relationships, attitudes, values and the environment.
Environment and values: Each organization has its own environment, context and bedrock values. Everyone needs to know what matters and why. Don’t try to do anything else until you’ve got that set.
Attitude is about choices: An organization’s overall strategy drives choices about which of its parts will be best in class (superior), world class (parity), strong (above average), or simplified/outsourced to be good enough. These choices help determine the need for a matrix and how best to design it.
Relationships and behaviors: This is why organizations have matrices. The most effective of them best balance focus and collaboration. They allow leaders and teams to build differential strengths and then work together to make the best possible decisions and scale enterprises with a creative tension that they could not do on their own.
My colleague Joe Durrett has worked all sides of matrix organizations in marketing at Procter & Gamble, sales and general management at Kraft General Foods and CEO of Information Resources, Broderbund Software and Advo. He has seen matrices at their best and at their worst and offered his perspective for this article along with his partners John Lawler and Linda Hlavac.

Istream type is an alias for the type of the cin object. It is used to read in data from the keyboard or other input sources, such as files. The operator ">>" is used to get data from the istream. With it, you can simply get input from the user in the command prompt (terminal). Command prompt (terminal) purpose is to help the user understand what input is expected, it is necessary to use a "prompt" string. If you prompt the user for information, you're essentially telling them what type of information to provide and how to format it.
The prompt string also helps to clarify what the program requires from the user and reduces user error. Therefore, option A, i.e., "To help the user understand what input is expected" is the correct option.Example: cin and cout#include using namespace std;int main(){ int x; cout << "Enter the value of x: "; cin >> x; cout << "The value you entered is: " << x; return 0;} Output:Enter the value of x: 12The value you entered is: 12Note: The program prompts the user to input the value of x with the string "Enter the value of x".

Answers
Z-test in Civil Engineering:
A civil engineering firm is conducting a study to compare the compressive strength of two types of concrete mixtures used in building construction. They collect a large sample of concrete specimens and measure their compressive strength. By performing a Z-test, they can determine if there is a significant difference in the mean compressive strength between the two mixtures. This information helps the firm make informed decisions about which concrete mixture to use in their future construction projects.
T-test in Civil Engineering:
A civil engineering company is evaluating the performance of a new construction material in comparison to an existing material for a specific application. They collect a smaller sample of test specimens and measure a particular property, such as tensile strength. By performing a T-test, they can assess if there is a significant difference in the mean tensile strength between the two materials. This analysis guides the company in determining the suitability and effectiveness of the new material for the intended application.
Both the Z-test and T-test are statistical tests commonly used in civil engineering research and analysis to compare means, assess significant differences, and make informed decisions based on collected data.
In civil engineering, At a significance level of 0.05 and 18 degrees of freedom (df = n1 + n2 - 2), the critical T-value is 2.101 for a two-tailed test.
Z-test Example: Suppose a construction company claims that the average strength of the concrete used in its buildings is 5000 psi. To test this claim, a sample of 25 concrete blocks is taken from the company's latest project and tested for strength. The mean strength of the sample is found to be 4800 psi with a standard deviation of 300 psi. Using a Z-test, the engineer can determine whether the company's claim is true or not.
T-test Example: Suppose an engineer wants to determine whether there is a significant difference in the compressive strength of concrete cylinders cured in water and those cured in air. To test this hypothesis, the engineer takes a sample of 10 concrete cylinders cured in water and 10 concrete cylinders cured in air. The mean compressive strength of the water-cured cylinders is found to be 5000 psi with a standard deviation of 250 psi.

Answers
The first-year saving would be: $19,728
How to calculate the first-year savingTo calculate the first-year saving, first note that the return on investment is the ratio between the investment benefit and the cost. So, the ROI of 36% represents this ratio.
Since the extra investment is $54,800 and the return on investment is 36%, then the first year saving would be
0.36 * $54,800 = $19,728

Explain briefly when each of the individual interviews and the group interviews should be chosen for determining requirements based on the following factors: Group interaction, Pressure, Sensitivity of subject, and Logistics requirement (Respondents assembling).
Answers
Individual interviews and group interviews are two approaches used for gathering requirements. The choice between these methods depends on various factors such as group interaction, pressure, sensitivity of the subject, and logistics requirements.
Each approach has its benefits and considerations, and the selection should align with the specific context and goals of the requirement-gathering process.
Individual interviews are suitable when there is a need for personalized interaction and in-depth exploration of individual perspectives. They provide an opportunity to delve into specific details and obtain candid responses. Individual interviews are beneficial in scenarios where the sensitivity of the subject matter is high, as they allow respondents to express their thoughts and concerns privately.
On the other hand, group interviews are valuable when group interaction and collaboration are important. They enable stakeholders to engage in a collective discussion, fostering idea generation, consensus building, and collaboration among participants. Group interviews are beneficial for capturing diverse viewpoints, identifying shared priorities, and promoting a sense of ownership among participants.
When time pressure is a consideration, individual interviews may be more efficient as they allow for focused discussions with one respondent at a time. Group interviews, on the other hand, may require more time due to the need to manage group dynamics and ensure equal participation.
Logistics requirements, such as the availability and proximity of respondents, can also influence the choice between individual and group interviews. Individual interviews can be conducted remotely or at different locations, while group interviews often require respondents to assemble at a specific venue.
In conclusion, the selection of individual interviews or group interviews depends on factors such as group interaction, pressure, the sensitivity of the subject, and logistics requirements. Evaluating these factors and considering the specific goals of the requirement-gathering process will help determine the most appropriate approach to gathering accurate and comprehensive requirements.

The gage pressure measured as 2.2 atm, the absolute pressure of gas is 3.2 bar. Please determine the local atmospheric pressure in kPa.
Answers
Answer:
\(97.085\ \text{kPa}\)
Explanation:
\(P_{g}\) = Gauge pressure = 2.2 atm = \(2.2\times 101325=222915\ \text{Pa}\)
\(P_{abs}\) = Absolute pressure = \(3.2\ \text{bar}=3.2\times 10^5\ \text{Pa}\)
\(P_{atm}\) = Local atmospheric pressure
Absolute pressure is given by
\(P_{abs}=P_{atm}+P_g\\\Rightarrow P_{atm}=P_{abs}-P_g\\\Rightarrow P_{atm}=3.2\times 10^5-222915\\\Rightarrow P_{atm}=97085\ \text{Pa}=97.085\ \text{kPa}\)
The local atmospheric pressure is \(97.085\ \text{kPa}\).
