Most technicians install rebuilt or new power steering pumps rather than overhauling the defective unit in the shop. True or False?
Answer:
Most technicians install rebuilt or new power steering pumps rather than overhauling the defective unit in the shop.
True
Explanation:
It has been established that most technicians, instead of overhauling the defective power steering pumps, prefer to install rebuilt or revamped pumps or even new pumps when they could have overhauled the unit themselves. Some are afraid that leakage could occur again. They are not confident enough to do the overhauling in-house or some claim that they do not have the time and other tools to carry out the overhauling. Acknowledgedly, overhauling a power steering pump is not a job for the novice. They require experienced and skilled hands to do the hard work.

Explanation:
A transmission channel between two communicating DTEs is made up of three sections. The first introduces an attenuation of 16 dB, the second introduces an amplification of 20 dB, and the third introduces an attenuation of 10 dB. Assuming a mean transmitted power level of 400 mW, determine the mean output power level of the channel. (3 points)
Answer:
the mean output power level of the channel is 100.475 mW
Explanation:
Given the data in the question;
for the first section; attenuation
16 = 10log₁₀ 400/P₂
P₂ = 10.0475 mW
For the second section; amplification
20 = 10log₁₀ p₂/10.0475
p₂ = 1004.75 mW
For the third section; attenuation
10 = 10log₁₀ p₂/1004.75
p₂ = 100.475 mW
i.e the mean output power level is 100.475 mW
or better still overall attenuation channel = ( 16 - 20) + 10 = 6dB
so
6 = 10log₁₀ 400/P₂
p₂ = 100.475 mV
the mean output power level of the channel is 100.475 mW
37. WHICH OF THESE STATEMENTS IS TRUE ABOUT KEEPING CHILDREN SAFE IN
VEHICLES?
A. Infants should not ride in the front seat of vehicles
B. Children under one year and over 20 lbs. should ride buckled up in the front seat
C. The back seat is generally not the safest place in the car for all children 12 years and younger
A
It would be B but I say that it isn't because children under 3 should be riding a buckle up just for safety

Zoning is like a butterfly because it is the final form of urban planning.
Zoning is like a stop sign because it is an obstacle to urban planning.
Zoning is like an egg because it is the process from which urban planning emerges.
Answer:
Zoning is like a hammer because it is used as a tool for urban planning.

Due to crashes at a railroad crossing in Salem, Oregon, an overpass (with a roadway surface 26 ft above the existing road) is to be constructed on an existing level highway. The existing highway has a design speed of 50 mi/h. The overpass structure is to be level, centered above the railroad, and 180 ft long. What length of the existing level highway must be reconstructed to provide an appropriate vertical alignment
Answer:
Oregon had 19 railroad crossing accidents in 2018, up from 10 in 2013. Marion County has more than most counties, logging 28 since 2008.
Explanation:
It provides explicit guidance to improve railroad crossing safety to support ODOT’s mission of a safe and efficient transporta-tion network, but is not a policy plan. Rather, it is an action plan to help ODOT achieve greater railroad crossing safety.
To establish a suitable vertical alignment, the present level highway's 2115-foot length needs to be rebuilt.
What is Vertical alignment?The ground's gradient and vertical curves are both included in vertical alignment.
For above given example,
Calculating the maximum permitted gradient is possible.
[tex]G = (V^2) / (29.83R)[/tex]
where, G is the gradient,
V is the design speed in mph.
R is the curvature's radius in feet.
[tex]G = (55^2) / (29.83 * 26)[/tex]= 0.72%
Calculating the minimum viewing distance as:
[tex]S = 1.47Vt + 2.3(t^2) / (3.5K) (3.5K)[/tex]
where t is the perception-reaction time in seconds, K is the coefficient of friction, and S is the minimum sight distance in feet.
The minimum sight distance can be estimated as follows using an assumption of a perception-reaction time of 2.5 seconds and a coefficient of friction of 0.3:
524.3 feet are equal to S = 1.47 x 55 x 2.5 + 2.3(2.52)/(3.5 x 0.3)
Now that we know how long the current level highway is,
The overpass's length and the sag curve's length are equal.
The following equation can be used to determine the length of the crest curve:
[tex]L = (S^2) / (8G)[/tex]
where L is the length of the crest curve, S is the shortest sight distance, and G is the highest permitted gradient.
[tex]L = (524.3^2) / (8 * 0.0072) = 188,607.8 ft[/tex]
The length of the sag curve, the length of the crest curve, and the length of the transition curves all make up the entire length of the level highway that needs to be rebuilt.
Assuming a 50-foot-long transition curve, we obtain:
Overall length is equal to 180 + 188,607.8 + (2 x 50) ft.= 2115 feet
Thus, the existing level highway measures 188,887.8 feet in length, which is equal to 2,265,853.6 inches or 2115 feet.

Your question is incomplete, most probably the complete question is:
Due to crashes at railroad crossing, an overpass (with a roadway surface 26 ft above the existing road) is be constructed on an existing level highway. see illustration below. the existing highway has a design speed of 55 mi/hr. the overpass structure is to be level, centered above the railroad, and 180 ft long.
What is the length of the existing level highway must be reconstructed to provide an appropriate vertical alignment? assume that the sag and crest vertical curves are directly connected (i.e., there is no constant grade section).

Why must fire extinguishers be routinely maintained
Answer:
Fire extinguishers controls the amount of pollution caused by smoke and burning. Although they have no expiring date, they won't last forever. Extinguishers should work for 5 to 15 years, but fire extinguishers be routinely maintained to make sure they remain effective.
