A 1.7 cm thick bar of soap is floating in water, with 1.1 cm of the bar underwater. Bath oil with a density of 890.0 kg/m{eq}^3 {/eq} is added and floats on top of the water. How high on the side of the bar will the oil reach when the soap is floating in only the oil?
Answers
Answer:
The height of the oil on the side of the bar when the soap is floating in only the oil is 1.236 cm
Explanation:
The water level on the bar soap = 1.1 m mark
Therefore, the proportion of the bar soap that is under the water is given by the relation;
Volume of bar soap = LW1.7
Volume under water = LW1.1
Volume floating = LW0.6
The relative density of the bar soap = Density of bar soap/(Density of water)
= m/LW1.7/(m/LW1.1) = 1.1/1.7
Given that the oil density = 890 kg/m³
Relative density of the oil to water = Density of the oil/(Density of water)
Relative density of the oil to water = 890/1000 = 0.89
Therefore, relative density of the bar soap to the relative density of the oil = (1.1/1.7)/0.89
Relative density of the bar soap to the oil = (1.1/0.89/1.7) = 1.236/1.7
Given that the relative density of the bar soap to the oil = Density of bar soap/(Density of oil) = m/LW1.7/(m/LWX) = X/1.7 = 1.236/1.7
Where:
X = The height of the oil on the side of the bar when the soap is floating in only the oil
Therefore;
X = 1.236 cm.

You are an architect invited to present the preliminary drawings to the structural team in order to brainstorm possible column locations on the first floor of a skyscraper. The meeting has been scheduled at the engineers’ office and five people will be present: you, your intern, the senior engineer, the structural engineer, and a mechanical engineer. What type of media would you use to present your drawing? Please justify your answer with your reasons and the outcomes you expect from the meeting.
Answers
Answer:
Explanation:I will bring the drawing of the skyscraper on my laptop, which will be equipped with a CAD software package. I will use an adaptor to project the drawings to a screen. The reasons I chose this is because CAD enables me to make the drawing efficiently and accurately. The software package will help avoid human error. Another advantage is that I can use layers to add new columns to the drawing so that I will not lose the original drawing. After I add the columns, we can view the structure in a three-dimensional view so that the structural engineer can check the location and dimensions of the column. The main advantage of CAD in this setting is that I can make immediate changes in the drawing, without having to change the entire drawing. This would not be possible if I used a paper-based presentation. Because I have my laptop at the meeting, I can also take notes about important points that arise during the meeting on a word processing program. I will be able to link the electronic document to the CAD file for further reference.
At the end of the meeting, I will be able to complete my drawings for the first floor of the skyscraper. The structural engineer can immediately approve the drawings and the mechanical engineer can then begin the preparation to start the build. The built-in features of the CAD software package enable the efficiency of this process.

Describing if the structure is low-level or high-level abstraction. Summarizing how each structure functions individually and part of the larger system. Describing the similarities between each side-by-side structure (i.e. how is a cell similar to a transistor
Answers
Answer:
[FIRST 2 SO FAR]
Explanation:
1. The cell and the transistor would be considered to be the lowest level of abstraction. This is because they are the smallest, basic building blocks that make up these structures.
The cell makes up the parts of the body and the transistors make up the computer. The cells take in nutrients from food, converts the nutrients into energy, and carry out specialized functions. Cells move around to convert chemical energy into mechanical energy, allowing the body to move. The transistors are like switches that turn on and off electric current (by controlling the movement of electrons, either stopping or starting the current). They store and move data from one place to another, allowing the computer or device to work.
These two structures are both the smallest part that makes up the main structure. They allow the larger structure that they are contained in to function by doing small tasks/activities in the structure.
2. The Tissue and Logic Gate are a lower-level abstraction because the are composed of smaller structures.
Tissues are groups of cells that perform one or more specific functions. Tissues (enforced by the cells) can control the movement of information that is spread through the surface of the body, protect and support organs, and allow entire body movement. Logic gates are the basic building blocks of digital system that can have more than one input and only one output. These input and output functions are determined by using logic, with the gates being named And, Or, and Not.
The two structures are similar because they allow the movement of something to flow through the bigger structure, allowing the structure to function. Logic Gates control the actions of the transistors by taking in multiple inputs, then uses logic to tell the transistor to turn on or off an electric current.

If the desired reliability is 90%, how long will the pavement last in years
Answers
The pavement will last between 41 and 50 years with a reliability of 90%.
A road surface, also known as pavement, is a durable surface material that is laid down on an area intended to support vehicular or pedestrian traffic, such as a road or walkway.
First, calculate the number of equivalent single axle loads (ESALS):
ESALS = 600*30 + 1400*20 = 55600.
Next, calculate the design life (L) using the formula: L =
(ESALS/18000)^(1/TSI) * (Ec/PSI)^(-1/2*SD).
Plugging in the values,
L = (55600/18000)^(1/2.5) * (5.5 x 10^6/4.5)^(-1/0.7) = 41.8.
Lastly, calculate the reliability (R) using the formula:
R = (1-LT^(-1/2))*100.
Calculating for a pavement life of 41 years and 50 years gives a reliability of 90% for both values.

The final specific volume in m³/kg is 0.0313 m³/kg.
Since \(Pv^{0.5} = constant\) where P = pressure and v = specific volume, we have
Since \(P_{1} v_{1}^{0.5} = P_{2} v_{2}^{0.5}\) where
P₁ = initial pressure = 250 kPa, v₁ = initial specific volume = V₁/m where V₁ = initial volume of gas = 1.5 m³ and m = mass of gas = 3 kg. so, v₁ = V₁/m = 1.5 m³/3 kg = 0.5 m³/kg, P₂ = final pressure = 100 kPa, v₂ = final specific volume of gasFinal Specific volumeMaking v₂ subject of the formula, we have

When the antiskid system is armed during flight, it is designed to prevent skidding of the aircraft's wheels during landing. However, in this state, current cannot flow to the antiskid control box. The reason for this is because the landing gear squat switch is open.
This switch is located on the main landing gear and is designed to detect when the wheels are on the ground during landing. When the switch is closed, it allows the current to flow to the antiskid control box. However, since the switch is open during flight, the current cannot reach the control box, even if the landing gear antiskid valves are open. Therefore, the landing gear squat switch plays a critical role in ensuring the proper functioning of the antiskid system during landing.

Working Principle Of Bourdon GaugeIf a tube having oval cross section is subjected to pressure its cross section tends to change from oval to circular.
Construction of a Bordon GaugeBourdon tube gauges consist of a circular tube.
One end of the tube is fixed while the other end is free to undergo elastic deformation under the effect of pressure.
Fixed end is open and pressure which is to be measured is applied at the fixed end.
Free end is closed and undergoes deformation under the effect of pressure.
Due to applied pressure the circular tube tends to uncoil and become straight along the dotted line.
Working of Bourdon Gauge
As the pressure is applied at the fixed end free end undergoes deformation.
The free end is attached with sector which further meshes with the pinion on which pointer is mounted.
Deformation of the pointer is transferred to pointer via this mechanism.
As a result point undergoes deflection and shows the pressure reading on calibrated dial.

a charged oil drop with a mass of 2 x 10–4 kg is held suspended by a downward electric field of 300 n/c. the charge on the drop is:
Answers
The given downward electric field E = 300 n/C. We are to determine the charge on the oil drop. The force acting on the oil drop, due to the electric field, is given by F = E × q, where q is the charge on the oil drop. Since the oil drop is held suspended.
The electric force acting on it is equal in magnitude to the gravitational force on the oil drop, i.e., mg, where m is the mass of the oil drop and g is the acceleration due to gravity. Since the oil drop is in equilibrium, the gravitational force acting on the oil drop is equal in magnitude to the electric force acting on it.
Hence, we have E × q = mg On substituting the given values, we have
q = mg / EQ
= 300 n/Cm
= 2 × 10–4 kg (given)
g = 9.8 m/s² On substituting the above values, we get
q = (2 × 10–4) × 9.8 / 300
≈ 6.5 × 10–6 C Therefore, the charge on the oil drop is 6.5 × 10–6 C.

T2 = 46.29C - 5
T2 = 41.29C
Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3
=5.074KW
Hence refrigerator load is 5.74Kg
(COP)r = 238/53
(Cop) = 4.490
Therefore the above values are the (a) mass flow rate of the refrigerant, b) the refrigerant load, c) the cop, and d) the minimum power input to the compressor for the same refrigeration load.

using house of Quality for an engineering design
Answers
The House of Quality is a tool used in engineering design to capture customer requirements and align them with engineering specifications.
The House of Quality is a widely used tool in the field of engineering design to ensure that customer requirements are effectively translated into engineering specifications. It provides a structured approach for capturing and organizing customer needs, determining the interrelationships between these needs, and aligning them with engineering characteristics or features. By using the House of Quality, engineers can prioritize design requirements, make informed decisions, and track the progress of design solutions.
For example, let's consider the design of a smartphone. The House of Quality for this design project would begin by identifying and prioritizing customer requirements through techniques like surveys, interviews, and market research. These customer requirements could include factors such as battery life, screen size, camera quality, durability, and user interface.
Next, engineers would determine the technical requirements or engineering characteristics that are necessary to meet these customer requirements. These technical requirements may include factors such as battery capacity, display resolution, processor speed, material selection, and operating system compatibility.
The House of Quality matrix is then created, where customer requirements are listed on one side, and technical requirements are listed on the other. The matrix allows engineers to identify the relationships between customer requirements and technical requirements, such as which technical features contribute most to satisfying specific customer needs.
By using the House of Quality, engineers can evaluate the importance of each customer requirement, prioritize design decisions, and track how well the design is meeting those requirements throughout the development process. It serves as a valuable tool for ensuring that the final product aligns with customer expectations and provides a systematic approach to engineering design.
