In engineering, a function or a feature has always been perceived as a particular process, active engagement, or workload a system must perform.
Generally differentiated consequently throughout the life span of infrastructure projects: Specifications as well as Functional technical specifications. Typically the Specifications define the most critical device attributes demanded.When working with paint, enamel, or sealant why is it important to have a ventilated area?
Answer:
The reason is that paints contain Volatile Organic Compounds VOC, which can lead to long-term health issues.
Exposure to paint fumes can lead to eye, throat, or nose, irritation, which can be soothed by the flow of fresh air.
Paint fumes VOCs inhalation from can cause side effects such as, throat eye, nose irritation, nausea, trouble breathing, and headache
Prolonged extensions to VOCs can lead to nervous system, kidneys, and liver damage.
As such it is important to have the paint work area well ventilated at all times.

The problem faced by Galloping Gertie, the failed bridge across the Tacoma Narrows, was caused because the engineers did not follow the perform tests on the prototype/testing/ step in the engineering design process.
Answer:
1) Perform
2) Prototype
Explanation:
The prototype testing phase of the design process to test the readiness of the design for the intended use
The prototype which is a first or early model of the project made so as to ensure proper functioning of the concept is to pass through general function test as well as design performance evaluation in a testing or lab setting
Other tests include, excessive stress test, testing to failure and other design tests.
Therefore;
The problem faced by Galloping Gertie the failed bridge across the Tacoma Narrows, was caused because the engineers did not perform tests on the prototype in the engineering design process.
For metallurgical reasons, it is desirable to melt the weld metal with minimum energy input. Which one of the following heat sources is most consistent with this objective: (a) high power, (b) high power density, (c) low power, or (d) low power density?
Answer:
The correct option is;
(a) High power density
Explanation:
The power density of a material is the amount of power per unit volume of the material. Power density, in the context of transformers, fuel cells, batteries, motors, and power supply units, is measured with respect to the volume, and the units is given as W/m³
A system such as a capacitor with an high power density has the capacity to put out large energy amount from a small volume. A capacitor with a high power density, can produce the same power output as a car battery and is said to have a high power density.

Asphixiation is a hazard posed by compressed natural gas (CNG) vehicles and can be detected when you notice this smell
a) Rotten Eggs
b)Cinnamon
c)Burning
d)spoiled milk
Answer:
The correct option is;
a) Rotten eggs
Explanation:
Asphyxiation hazard posed by compressed natural gas (CNG) can be detected when the smell of rotten eggs is noticed
Compressed natural gas is made 90% of the colorless and odorless gas, but highly combustible gas, methane, a gaseous additive known as Mercaptan that has the smell of rotten eggs is added so that a person can become alerted by the smell given off in the system should there be a leak.
The smell of the Mercaptan can be detected as low as when the concentration of the the CNG is 1/16 times the concentration required for the combustion of the CNG.

A wind turbine rotates at 20 rev/min. If its power output is 2.0 MW, the torque produced on the turbine from the wind is
Answer:
The torque torque produced on the turbine from the wind is approximately 955 kN·m
Explanation:
The number of revolution per minute of the turbine = 20 rev/min
The power output of the turbine = 2.0 MW
The power transmitted to a shaft equation is given as follows;
[tex]Power , \ P = \dfrac{2 \cdot \pi \cdot N \cdot T}{60}[/tex]
Where;
P = The power transmitted to a turbine shaft = 2.0 MW
N = The number or revolutions per minute = 20 rev/min
T = The torque produced on the turbine by the wind
Therefore;
[tex]Torque , \ T = \dfrac{P \cdot 60}{2 \cdot \pi \cdot N } = \dfrac{2.0 \times 60}{2 \times \pi \times 20} = \dfrac{3}{\pi } \ MN \cdot m[/tex]
The torque torque produced on the turbine from the wind = 3/π MN·m ≈ 0.955 MN·m = 955 kN·m.
An engineer has designed and built a prototype to improve the brake system of a car. What is the next step that the engineer should take in the process
Answer:
Test the working prototype
Explanation:
After the prototype is built, it is put through basic operational tests and purpose of applicability or performance test
The prototype is also laboratory tested to determine how reliable it is with tests performed to determine the modes of failure. Performance of tests are carried out by subjecting the prototype to stresses beyond its designed stress such as to discover failure modes
The system is however tested in isolation at this stage and the performance and risks of the prototype are quantified after the test, with improvement requirement outlined for modification of the design.

Technician A says that squeeze-type resistance spot welding (STRSW) may be used on open butt joints. Technician B says that replacement spot welds may be made adjacent to the original spot weld locations. Who is right
Answer:
B only
Explanation:
Squeeze-type resistance spot welding (STRSW)is a type of electric resistance welding that brings about the weld on interfacing sheet metal pieces through which heat generated from electric resistance bring about fusion and welding of the two pieces together
Therefore, it is not meant for opening but joints but it can be used for making replacement spot welds adjacent to the original spot weld due to the smaller heat affected zone (HAZ) created by the STRSW process.
Technician A says that cut locations for sectioning joints may be identified by a die mark stamped into the part. Technician B says that a vehicle maker recommended sectioning cut location may be identified as a precise measurement from a reference point. Who is right
Answer:
Both A ad B are right
Explanation:
A sectioning joint are joints that are pieces to butted, spaced two to three metal thickness apart
Cut locations on a metal parts are made by die marks stamped to the part to enable the cutter to locate the cut location
The cut location can be specified on a model diagram such that when such a required cut is to be made a reference point to the cut location is specified for quality and accuracy.

Explanation:
You have learned about the different factors that affect acceleration and braking. The driving is unsafe around the ambulance and police car when travel at the speed limit.
What is acceleration?
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
When an individual is driving, he must drive in a speed limit mentioned according to the driving law. When you are driving in safe limit, you are still unsafe around some vehicles.
