List the key features of each house and explain how those features make it hurricane resistant.

Answers

Answer 1

The key features of each house make them hurricane resistant by providing strength and stability against high winds, debris, and flooding. The reinforced concrete walls and roof of a concrete house, the steel frame of a steel house, and the timber frame covered with structural panels of a timber frame house all provide excellent protection during a hurricane.

Here are the key features of each house and how they make them hurricane resistant:

1. Concrete house: The main feature of a concrete house is its reinforced concrete walls and roof. This means that it is designed to withstand high winds, debris, and even floods. The foundation is also made of concrete, which helps prevent the house from shifting or sinking during flooding or high winds. The windows and doors are usually made of impact-resistant glass, which can withstand debris flying at high speeds during a hurricane.

2. Steel house: The key feature of a steel house is its frame. The frame is made of steel, which is incredibly strong and can withstand high winds and debris. The steel frame is bolted to a concrete foundation, which adds even more stability to the house. The walls and roof are usually made of metal panels, which are lightweight but very durable. The windows and doors are also impact-resistant and are usually made of laminated glass.

3. Timber frame house: Timber frame houses are built with a frame made of timber, which is then covered with structural panels made of materials like OSB or plywood. This provides a very sturdy and stable structure. The roof is usually made of metal panels, which are lightweight but very durable. The windows and doors are also impact-resistant and are usually made of laminated glass.

To answer regarding the external load that would just cause the joint to separate when fastening together a double D-ring using a single bolt and nut, we need to consider the following factors:

1. The tensile strength of the bolt
2. The tensile strength of the D-ring
3. The clamping force provided by the bolt and nut

Once we have this information, we can determine the weakest component in the assembly, as that will dictate the external load at which the joint will separate.

Here is a step-by-step explanation of how to find the external load that would cause the joint to separate:

Step 1: Determine the tensile strength of the bolt and the D-ring.
Step 2: Determine the clamping force provided by the bolt and nut.
Step 3: Identify the weakest component in the assembly (either the bolt, D-ring, or clamping force).
Step 4: Use the weakest component's strength to calculate the external load that would cause the joint to separate.

Without specific data for the bolt, D-ring, and clamping force, we cannot provide an exact value for the external load that would cause the joint to separate. However, by following these steps, you can determine the answer once you have the necessary data.

Determine for the cyclea.the actual heat transfer to the working fluid passing through thesteam generator, in kJ per kg of steam flowing.b.the thermal efficiency.c.the actual heat transfer from the working fluid passing through thecondenser to the cooling water, in kJ per kg of steam flowing

Answers

Answer:

Explanation:

Given that:

Superheated vapor enters the turbine at 10 MPa, 480°C,

From the tables of superheated steam tables; the following values are obtained

\(h_1 = 3322.02 \ kJ/kg\\\\ s_1 = 6.52846 \ kJ/kg.K\)

Also; from the system, the isentropic line is 1-2 in which s_2 is in wet state

\(s_2 = s_{f \ 6 kpa} +xs_{fg \ 6 kpa}\)

\(s_2 =0.51624 + x(7.82)\)

\(s_2 =0.51624 + 7.82x\)

From the values obtained;

\(s_1 =s_2= 6.52846 \ kJ/kg.K\)

Therefore;

6.52846 = 0.51624+7.82x

6.52846 - 0.51624 = 7.82 x

6.01222  = 7.82 x

x = 6.01222/7.82

x = 0.7688

The enthalpy for this process at state (s_2) can be determined as follows:

\(h_2 = h _f +xh_{fg} \\ \\ h_2 = 150.15 +(0.77 \times 2415.92) \\ \\ h_2 =150.15 +( 1629.2584 ) \\ \\ h_2 =2010.4084 \ kJ/kg\)

The actual enthalpy at s_2 by using the isentropic efficiency of the turbine can determined by using the expression:

\(n_T = \dfrac{h_1-h_{2a}}{h_1-h_2}\)

\(0.8 = \dfrac{3322.02-h_{2a}}{3322.02-2010.4084}\)

\(0.8 = \dfrac{3322.02-h_{2a}}{1311.6116}\)

\(0.8 * {1311.6116}= {3322.02-h_{2a}\)

\(1049.28928= {3322.02-h_{2a}\)

\(h_{2a}= {3322.02- 1049.28928\)

\(h_{2a}= 2272.73072\) kJ/kg

The work pump is calculated by applying the formula:

\(w_p = v_{f \ 6 kpa} (p_4-p_3)\)

\(w_p = 0.0010062 * (10000-6)\)

\(w_p = 0.0010062 *9994\)

\(w_p = 10.0559628 \ kJ/kg\)

However;

\(w_p = h_4 -h_3\)

From the process;

\(h_3 = h_{f(6 kpa)} = 150.15 \ kJ/kg\)

\(10.0559628 = h_4 - 150.15\)

\(10.0559628+ 150.15 = h_4\)

\(160.2059628= h_4\)

\(h_4= 160.2059628 \ kJ/kg\)

The actual enthalpy at s_4 by using the isentropic efficiency of the turbine can determined by using the expression:

\(n_P = \dfrac{h_4-h_{3}}{h_{4a}-h_3}\)

b) 145m2
c) 145.5m
d) 135.36m
.​

Answers

Answer: 150m

Explanation:

The following can be depicted from the question:

Dimensions of outer walls = 9.7m × 14.7m.

Thickness of the wall = 0.30 m

Therefore, the plinth area of the building will be:

= (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)

= 10 × 15

= 150m

The plinth area will be 150m.

Given information

Dimensions of outer walls = 9.7m × 14.7m.

Thickness of the wall = 0.30 m

Plinth area of the building = (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)

Plinth area of the building = 10 × 15

Design a fourbar Grashof crank-rocker for 90 degree of output rocker motion with no quick return. Build a model and determine the toggle positions and the minimum transmission angle from the model.

Answers

The design of a four-bar Grashof crank-rocker mechanism for 90 degrees of output rocker motion with no quick return requires determining appropriate link lengths and pivot locations while satisfying the Grashof condition.

To design a four-bar Grashof crank-rocker mechanism with 90 degrees of output rocker motion and no quick return, we need to determine the appropriate link lengths and pivot locations. The Grashof condition states that for a four-bar mechanism to have continuous rotation, the sum of the shortest and longest link lengths should be less than or equal to the sum of the other two link lengths.

Here's an example design that satisfies the given requirements:

1. Define the lengths of the four links:

Let's assume the lengths of the links as follows:

Link 1 (input crank): L1Link 2 (coupler): L2Link 3 (output rocker): L3Link 4 (fixed): L4

2. Determine the pivot locations:

For this mechanism, we need to select the pivot locations carefully to achieve the desired motion. We'll assume that pivot A is the input crank pivot, pivot B is the coupler pivot, pivot C is the output rocker pivot, and pivot D is the fixed pivot.

3. Establish the desired motion:

We want the output rocker to move 90 degrees, which means that the angle at pivot C will change from 0 to 90 degrees.

4. Calculate the required link lengths:

Using the law of cosines, we can determine the length of the coupler link (L2):

L2 = sqrt((L1^2) + (L3^2) - (2 * L1 * L3 * cos(90 degrees))) L2 = sqrt(L1^2 + L3^2)

5. Ensure the Grashof condition is satisfied:

To avoid a quick return, we need to ensure that the mechanism is a Grashof mechanism. In this case, we want the mechanism to be a Grashof crank-rocker, so the sum of the shortest and longest link lengths should be less than or equal to the sum of the other two link lengths.In our case, the shortest and longest links are L2 and L4, respectively, while the other two links are L1 and L3. So, we need to ensure that L2 + L4 <= L1 + L3.

6. Determine toggle positions:

The toggle positions are the extreme positions where the mechanism reaches its maximum and minimum transmission angles. These positions occur when the mechanism is nearly straight or fully extended. The transmission angle is the angle between the coupler link and the rocker link.

7. Calculate the minimum transmission angle:

The minimum transmission angle can be determined by finding the position where the transmission angle is at its minimum value. This occurs when the mechanism is in its toggle position(s).

It's worth noting that there can be multiple solutions that satisfy the given requirements. The example above outlines the general steps to design such a mechanism, but the specific link lengths and toggle positions would depend on the desired proportions and constraints of your application.

D) Design Period: It is the length of time for which a particular engineering project is designed to function effectively. For example, in the case of water supply systems, the design period may be 20-30 years, during which the system is expected to meet the water demand requirements of the users.

E) Drop Manhole: It is a type of manhole that is constructed at a location where the sewer pipe changes direction from a horizontal to a vertical alignment. The purpose of a drop manhole is to reduce the velocity of the sewage flow and prevent damage to the downstream sewer structures.

F) Self Cleansing Velocity: It is the minimum velocity required in a sewer pipe to prevent the deposition of solids and ensure the self-cleansing of the pipe. A value of twice the average velocity is commonly used as the self-cleansing velocity.

The factors that affect water demand include population size, economic activity, climate, lifestyle, and water pricing policies. Changes in any of these factors can influence the level of water demand in a given area. For example, an increase in population size or economic activity can lead to a higher demand for water, while the implementation of water conservation measures can reduce water demand.

__________________________________________________________

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 stress

This 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:

w = distributed load (15 kN/m)l = length of beam (1 m)

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:

\(M_{1}=7.5\text{kN-m}\)\(I_{xx}=2.7\times10^7\:\text{mm}^4\)y = 150mm

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:

\(P_{z,U}^2= -20850\:N\)\(P_{y,U}^2=0\)

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:

W = 15 kN/m\(\delta_z=1\:m\)\(P_{y,L}=2085\:N\)

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:

\(q=\boxed{46.8\:N/mm}\)

C. Show float
D. Describe the WBS

Answers

Gantt Charts are used to show the overall length of the project and each activity.

What is gantt chart ?

A Gantt chart is a sort of bar chart that shows a project timetable. It was created by Henry Gantt, who popularized the format between the years of 1910 and 1915. The dependence structures between activities and the state of the current schedule are also displayed in modern Gantt charts.

A Gantt chart is a project management tool that helps with the planning and scheduling of projects of all kinds. They are especially helpful for streamlining complex projects, though.

Assuming the friction angle remains the same, determine: 2.3.1 the shear plane angle (5) 2.3.2 the chip thickness

Answers

The shear plane angle is approximately 28.85°.2.2 The shear strain is approximately -1.3276.2.3.1 The new shear plane angle is approximately 45°.2.3.2 The new chip thickness is -∞.

From the given data; In an orthogonal cutting operation, the tool has a rake angle of -5°.The chip thickness before the cut = 0,3048 mm and the cut yield a deformed chip thickness = 0,7112 mm.2.1 Shear plane angle (β)The shear plane angle can be found out using the following formula: tan β = (cot α + μ_tan α) / (1-μ_cot α)where;α = tool angleμ = coefficient of friction In the given case,μ = 0.4α = -5°β = tan⁻¹ [(cot (-5°) + 0.4 tan (-5°)) / (1-0.4 cot (-5°))]≈ 28.85°Therefore, the shear plane angle (β) is approximately 28.85°.2.2 Shear strain (γ)The shear strain (γ) can be determined using the following formula:γ = (t₀ - t) / t where; t₀ = initial chip thickness = 0.3048 mm t = final deformed chip thickness = 0.7112 mmγ = (0.3048 - 0.7112) / 0.3048≈ -1.3276Therefore, the shear strain (γ) is approximately -1.3276.2.3 Change in rake angle If the rake angle is changed to 0°, the new shear plane angle (β') and chip thickness (t') can be determined using the following formulas: tan β' = (cot α + μ_tan α) / (1-μ_cot α)where;α = tool angle = 0°μ = coefficient of friction = 0.4t' = t₀ - (tan β') / tan αwhere;α = tool angle = 0°t₀ = initial chip thickness = 0.3048 mm tan β' = (cot 0° + 0.4 tan 0°) / (1-0.4 cot 0°)≈ 45°t' = 0.3048 - (tan 45°) / tan 0°= 0.3048 - ∞= -∞

The following are violations of the CAA venting prohibition:A) Release of refrigerants because appliances were not recovered.B) Releasing isobutane while servicing equipment.C) Releasing HFC refrigerant because of catastrophic equipment failure.D) Refrigerants released when disconnecting non low-loss hoses to service an appliance.

The Clean Air Act (CAA) is a United States federal law passed in 1963 that aimed to reduce air pollution in the United States. It was established to protect and improve air quality and to avoid risks to human health and the environment.What is the Venting Prohibition in CAA?Section 608 of the CAA prohibits the release of ozone-depleting substances (ODS) and substitute refrigerants (like HFCs) into the atmosphere during the maintenance, service, repair, or disposal of refrigeration and air-conditioning equipment, as well as during the disposal of appliances and vehicles, that contain ODS or substitute refrigerants.

It is also prohibited to release these substances when disposing of air conditioning and refrigeration equipment, including refrigerant, which is prohibited by law.So, A, B, C and D are violations of the CAA venting prohibition because they release refrigerants.
