Voltage drop testing is being discussed.
Technician A connects the red voltmeter lead to the most positive side of the circuit being tested and the black lead to the most negative side or part of the circuit being tested. Technician B says the test must be conducted with the circuit operating with normal amounts of current. Who is correct?
Answer:
Technician B only is correct
Explanation:
Voltage drop testing is a method used to find the amount of electrical resistance available in an high amperage circuit that involves connecting the leads of the meter in parallel to the circuits being tested such that disassembly is not required
In voltage drop test, the red voltmeter lead and black voltmeter lead are placed at two points on the same side of the circuit connection such that the leads are in between two positive connection or two negative connection (rather than connecting the red to the positive and the black to the negative sides of the circuit) and digital voltmeter is used for the voltage drop measurement across the lead while the connection is under load.
Therefore, Technician B only is correct
Electrical Engineering dates back to which century?
A tornado may be simulated as a two-part circulating flow in cylindrical coordinates, with Vr = Vz = 0. Vtheta = ωr if r ≤ R and Vtheta = ωR2 / r if r ≥ R. Determine the vorticity and the strain rates in each part of the flow.
Explanation:
\($V_{\theta} = \omega r , r \leq R $\)
= \($\omega \frac{R^2}{r} $\) , r> R
\($V_r = V_z = 0$\)
Inner region vorticity
\(\Omega _z =\frac{1}{r}.\frac{d}{dt}(rv_{\theta})\)
\(\Omega _z =\frac{1}{r}.\frac{d}{dt}(r\omega r), (e\omega \neq 0)\) (rotational)
Outer region vorticity
\(\Omega _z =\frac{1}{r}.\frac{d}{dt}(\omega e^2/r)\)
= 0 (irrotational)
Strain rate of the inner region
\(e_{\theta \theta}=\frac{1}{r}.\frac{\delta u_{\theta}}{\delta \theta}+\frac{u_r}{r}=0\)
\(e_{z z}=\frac{\delta u_z}{\delta z}=0\)
\(e_{r r}=\frac{\delta u_r}{\delta r}=0\)
\(e_{r \theta}=e_{\theta r}=\frac{1}{2}\left \{ r.\frac{\delta}{\delta r} \left ( \frac{u_{\theta}}{r} \right )+\frac{1}{r}.\frac{\delta u_r}{\delta \theta}\right \}\)
\(e_{r \theta}=e_{\theta r}=\frac{1}{2}\left \{ r.\frac{\delta}{\delta r} \left ( \frac{\omega r}{r}+\frac{1}{r}(0) \right )\right \}\)
= 0
Therefore, the strain rate are 0.
\(e_{r \theta }= e_{\theta r} =\frac{1}{2}\left \{ r \frac{\delta}{\delta r} \left ( \frac{\delta u_{\theta}}{\delta r} \right )+\frac{1}{r}\frac{\delta v_r}{\delta \theta} \right \}\)
\(= \frac{1}{2}\left \{ r. \frac{\delta}{\delta r}\left ( \frac{\omega R^2}{r^2} \right )+\frac{1}{r}. \frac{\delta v_r}{\delta \theta} \right \}\)
\(= \frac{1}{2}\left \{ v-\frac{2}{v^3} .\omega R^2 \right \}\)
\(= -\frac{\omega R^2}{r^2}\)

Summarize three reasons why respect for local geography and culture are important to green engineering.
Answer:
Ensure that all material and energy inputs and outputs are as inherently safe and benign as possible. Minimize the depletion of natural resources. Prevent waste. Develop and apply engineering solutions while being cognizant of local geography, aspirations, and cultures.Green engineering is the design, commercialization, and use of processes and products that minimize pollution, promote sustainability, and protect human health without sacrificing economic viability and efficiency.The goal of environmental engineering is to ensure that societal development and the use of water, land and air resources are sustainable. This goal is achieved by managing these resources so that environmental pollution and degradation is minimized.
Explanation:i helped
Explanation:
One possible reason for this query could be the amount of trees per say would have to be cut down to construct the green engineering facilities. Another thing could be distance from other facilities. For example you wouldn't want a green engineering facility next to a fossil fuel burning facility. (That would be pointless.) Before comensing the green engineering process, you would also like to ask local officers for any enviornmental information that could be used during the making of this, since there may be endangered animals or things that could be affected by the construction. You would also not like a location near a big town or city since the noise or the very mild pollution may bother the locals.

When driving during the daytime in reduced visibility, such as rain, smoke, or fog,
A: You must turn on your low beam headlights,
B: You should turn on only your parking lights,
C: You must turn on your four-way emergency flashers.
Answer:A
Explanation:
When driving in fog, it is best to drive with -Low beam headlights to see better.
For a distance of 50 to 75 meters in front of your vehicle, low beam headlights are helpful. Low beam headlights, as opposed to daytime running lights, increase your visibility to oncoming traffic as well as in low light conditions such as rain, snow, and fog. They also make you more visible to other drivers. The precise times that these lights must be used are therefore specified by the law.
The use of headlamps in low beam headlights is restricted to those with white light, it is first important to note. Asymmetrical light shine is the main characteristic of low beam headlights. As a result, oncoming traffic isn't dazzled and you can see lane markings, signs, and obstacles clearly and in good time while the right side of the road is illuminated more than the left.

4. Tony Hawk weighs about 60 kg. Calculate the difference in the pressure placed on the snow if he was standing in the snow on one snowshoe compared to standing in the snow in one boot. The area of the snowshoe is 0.20 m² and the area of the boot is 0.05 m².
The difference in pressure placed on the snow when Tony Hawk stands on one snowshoe compared to standing in one boot is 800 Pa.
1. Convert the weight of Tony Hawk from kg to N (Newton):
Weight = Mass x Gravity
Given that Tony Hawk weighs about 60 kg and the acceleration due to gravity is approximately 9.8 m/s²,
Weight = 60 kg x 9.8 m/s² = 588 N
2. Calculate the pressure exerted by Tony Hawk on the snow when standing on one snowshoe:
Pressure = Force / Area
Given that the area of the snowshoe is 0.20 m²,
Pressure on snowshoe = 588 N / 0.20 m² = 2940 Pa
3. Calculate the pressure exerted by Tony Hawk on the snow when standing in one boot:
Given that the area of the boot is 0.05 m²,
Pressure on boot = 588 N / 0.05 m² = 11760 Pa
4. Calculate the difference in pressure placed on the snow:
Difference in pressure = Pressure on snowshoe - Pressure on boot
Difference in pressure = 2940 Pa - 11760 Pa = -8820 Pa
Note: The negative sign indicates that the pressure on the snowshoe is lower compared to the pressure on the boot. However, in this context, the absolute value of the difference (8820 Pa) represents the magnitude of the pressure difference.

the ____ method is the safest turning technique to use as it does not expose your hands to the airbags deployment area
Answer:
Push/pull Method
Explanation:
Push/pull method is seen as the best method to use when a driver what to steer a wheel to point the car in a particular direction reason been that PUSH/PULL method enables the driver to sit perfectly well in order to firmly hold the wheel which is why this method is often recommended as the safest and most effective way of steering than other steering method.
Therefore the PUSH/PULL method is the safest and the best turning technique to use because it does not expose the driver hands to the airbags area reason been that air bag are sometimes place in the centre of the steering wheel which means that when a driver cross his/her arms when steering will block the air bag in a situation where the air bag needed to explode out because airbag can explodes out with a lot of force which in turn could force the driver arms towards his/ her face which is dangerous.

A driver complains that his front tires are wearing
excessively at the center of the tread surface. Techni-
cian A says the wear problem is caused by underin-
flation. Technician B says the problem is caused by
excessive camber. Who is right?
(A) A only.
(B) B only.
(C) Both A & B.
(D) Neither A nor B.
Answer:
The correct option is;
Neither A nor B
Explanation:
The location of the where the thread wears in tire that has too high inflation is at the thread pattern center due to the reduced size of the contact patch with the load of the car resting on the central portion of the tire's contact surface
When the wear occurs at the outer edges of the tire, the load of the car rests on the outer edges as the contact patch increases due to the tire being under-inflated
Camber is the slope provided in road pavement to drain off water from the road
Roads with camber has a raised middle portion and wear due to camber includes outer-edge tread wear, inner-edge tread wear and tire feathering
