Answer:
stress = 8,556 Psi. or (stress = 59 Mpa)
Explanation:
stress = force / area
force P = 3 tons (convert to lbs. for units consistency)
1 ton = 2240 lbs.
P = 6,720 lbs.
steel bar Diameter D = 1 in. (convert to d
Area of steel bar = (π * 1²) / 4 = 0.785 in²
therefore, stress = 6720 lbs. / 0.785 in²
stress = 8,556 Psi.
in Mpa ----- 8556 Psi * 0.00689476 MPa/Psi = 59 Mpa
A large piece of ground is developed with lights, streets, and sewers. The subdivider wants to get it ready for building. He does an environmental impact statement and makes a large map which shows where each lot and block is located. Streets, parks, and utility easement are also shown. This is visual representation is called:
Answer:
Subdivision plat map
Explanation:
A subdivision plat map is a map plan of a given scale having the planned lot subdivisions and amenities. Subdivision plat map also show easement boundaries, access routes, streets and alleyways present in or adjacent to the tract of land that is being subdivided into lots
The process of subdivision of a tract land of land requires the approval the counties and the cities in which the land is located.
6. Driving with parking lights only (in place of headlights) is against the law. A. True B. False
Answer:
B false it is illegal to only have got fog lights on though and bright headlights because it can distract other drivers going last and if the y are distracted then that will cause a collision
Hope this helps :)
Explanation:
Question 6: Which of the following is NOT true if you are changing into a
turning lane?
You should activate your signals 100 feet beforehand
You should activate your signals when you get into the turn lane
You should activate your signals before you get into the turn lane
You should use your hands to signal if your lights do not work
Answer:
You should activate your signals 100 feet before you turn, becuase of that you should not wait until you are turning to turn on your signals. If you do not have working lights use your hands. So the answer that is inccorect is B.
You should activate your signals when you get into the turn lane is NOT true
Because you are supposed to single beforhand not while you're in the lane.

Your friend wears earbuds while driving to school each day. Is this safe? Is it legal? Explain why or why not.
Answer:
Its not safe but it isn't illegal. Its not safe because if their volume was up they wouldn't be able to hear if someone is honking at them or listen to emergency vehicles. They would be oblivious to what's going on around them.

Which type of engineering design uses an already existing design?
A. top-down design
B. spiral design
C. bottom-up design
D.
incremental design
Answer:
The correct option is;
C. Bottom-up design
Explanation:
The bottom-up design is meant for system redesign or re-engineering of an existing design involving component upgrading or legacy systems replacement
The bottom-up design approach is also meant for applications where there is a new interface requirement for the original system in order to determine the functionality of the newly combined systems and also where a novel component is incorporated into the existing design.
The bottom-up approach starts with the analysis of the interoperability of the components to the modules and eventually the analysis of the system requirements.

Answer:
Improve Your Writing
You may need to improve your ability to express yourself in writing.
To some degree, most organisations rely on the accurate transfer of information and that calls for the accurate use of language. When speaking, most people make multiple errors of grammar and vocabulary, and nobody seems to mind. But when you are doing business at work, then the business agreement is usually in the form of a written document; and that document has to be worded properly.
How would you rate your ability to express yourself properly in writing? Are you a good writer or do you lack knowledge of grammar, punctuation, logic and rhetoric?
If you are not as good at writing as you need to be, then study grammar, study punctuation, logic and rhetoric.
Start by buying a copy of a book called 'Rex Barks' by Phyllis Davenport.
This book is the gateway to grammar - and Phyllis is phenomenal.
Explanation:
Steam enters an adiabatic turbine at 8 MPa and 500 C with a mass flow rate of 3 kg/s andleaves at 30 kPa.The isentropic efficiency of the turbine is 0.90. Neglecting the kinetic energy change of the steam, determine (a) the tem-perature at the turbine exit and (b) the power output of theturbine
Answer:
(a) The exit temperature = 69.1°C
(b) The power output = 8.3 MW
Explanation:
(a) The enthalpy of steam at 8 MPa and 500°C is given (from online sources) as h₁ = 3399 kJ/kg
The exit temperature = The saturation temperature at 30 kPa = T₄ = 69.096 + 273.15 = 342.246 K
The exit temperature = 69.1°C
(b) The mass flow rate = 3 kg/s
The isentropic efficiency = 0.9 = (h₁ - h₂)/(h₁ - h₂[tex]_s[/tex])
s₁ = 6.727 kJ/kgK
h₂[tex]_s[/tex] = 289.229+ 2335.32* (6.8235 - 6.727 )/6.8235 = 322.26 kJ/kg
Therefore, h₂ = h₁ - (h₁ - h₂[tex]_s[/tex])*0.9
h₂ = 3399 - (3399 - 322.26 )*0.9 = 629.934 kJ/kg
The power output = [tex]\dot m[/tex](h₁ - h₂) = 3 *(3399 - 629.934) = 8307.2 kJ/s =
8.3 MW.

If sail boats A and B are approaching each other with the wind on different sides, why is vessel A considered the give-way vessel (vessel that must take early and substantial action to avoid a collision)?
Answer:
The reason is because when the wind approaches each sailboat from a different side, the sailboat that the wind approaches from the port side, which is the left side is the give-way vessel.
Whereby the wind approaches the vessel A from the port (left) side then vessel A is considered the give-way vessel
The give-way vessel is the vessel that will have to take expeditious steps to create access for the other vessels by either changing course, stopping, or moving with reduced speed
Explanation:
4. Two technicians are discussing the evaporative emission monitor. Technician A says that serious monitor faults cause a blinking malfunction indicator lamp
(MIL) or even an engine shutdown. Technician B says that the engine computer will run the EVAP monitor when fuel level is within 15 to 25 percent and the TP
sensor position is between 9 and 10 percent. Who is correct?
O A. Neither Technician A nor B
O B. Both Technicians A and BN
O C. Technician A
OD. Technician B
Answer:
The correct option is;
Neither Technician A nor B
Explanation:
The evaporative emission monitor or Evaporaive Emission Control System EVAP System monitors enables the Power Control Module of the car to check fuel system leak integrity and the vapor consumption efficiency during engine combustion
It is a requirement of EPA on cars to check the emission of smug forming evaporates from cars
Serious monitor faults can cause the turning on of the check engine lights and the vehicle will not pass OBD II test, but it will not lead to engine shutdown
It runs when the engine is 15 to 85% full and the TP sensor is between 9% and 35%.
Therefore, the correct option is that neither Technician A nor B are correct.

2. What is the charge, expressed in micro coulombs on two equally and similarly charges spheres placed in air with their centres 30 cm apart repelling each other with a force of 120 mgm.
Answer:
q = 0.1086 micro Coulombs
Explanation:
By Coulombs law, we have;
[tex]F =k \times \dfrac{ q_1 \times q_2}{r^2}[/tex]
Where;
F = The electric force = 120 mgm
q₁ and q₂ = Charge
r = The separating distance = 30 cm = 0.3 m
k = 8.9876×10⁹ kg·m³/(s²·C²)
Where, q₁ and q₂, we have;
[tex]F =k \times \dfrac{ q^2}{r^2}[/tex]
Whereby the force is the force of 120 milligram mass, we have;
0.00012 × 9.81 = 000011772 N
[tex]q = \sqrt{ \dfrac{ F\times r^2}{k}}[/tex]
Substituting the values, we have;
[tex]q = \sqrt{ \dfrac{ 000011772 \times (0.3)^2}{8.9876 \times 10^9}} = 1.086 \times 10 ^{-7} \ Coulombs[/tex]
q = 0.1086 micro Coulombs.
