) Chain drive ratio is a the ratio between the rotational speeds of the input and output _________ of a roller chain drive system.
Answer:
Sprockets.
Explanation:
A chain drive is an efficient technique used for the transmission of mechanical power from one point to another. For example, it is used for transmitting power to the wheels of a bicycle, motorcycle, motor vehicle and other machineries such as chain saw etc.
Chain drive ratio is the ratio between the rotational speeds of the input and output sprockets of a roller chain drive system. This ultimately implies that, chain drive ratio is the ratio of the number of teeth on the driving sprocket (T1) divided to the number of teeth on the driven sprocket (T2).
Also, the chain drive ratio can be calculated by dividing the number of teeth on the large sprocket by the number of teeth on the small sprocket.
Additionally, the rotational speed of a sprocket is measured in revolutions per minute (RPM).
One of the issues with the roller chain is that, as the roller chain moves round the sprocket link by link, it affects its speed (surge) due to the change in acceleration and deceleration i.e the rise and fall of its pitch line.

You are driving on a multi-lane road, and are following the vehicle in front of you at a safe distance. But then a car changes lanes into the gap in front of you, and slows down because the gap in front o them is too small. You should
A.Honk your horn, and then gradually drop back further behind the slowing car.
B.Quickly try to change lanes, and pass the slowing car if you can.
C.Slow down and drop back to a safe following distance behind the slowing car.
Answer:
C. Slow down and drop back to a safe following distance behind the slowing car.
Explanation:
the highway code contains the rules and regulations guiding the conduct of road users on a motorable roads. It is very important that a driver concentrates on the situation on the road whenever he/she is driving to reduce the event of avoidable accidents.
In the given scenario, since the car that changed lanes slows down due to small gap at its front, the appropriate thing to do is to slow down and follow by keeping a safe distance behind the slowing car.
Answer:
C.Slow down and drop back to a safe following distance behind the slowing car.
Explanation:
I got this correct
Jamal has Started all season as a safety. Last season,he was making a backup salary, which is 67% of what starters make. If Jamal is able to renegotiate his contract to the starter rate from the $400,000 he's currently making, what will his next salary be?round to the nearest whole number.
Answer: $597015
Explanation:
Let the salary of the starter be x.
Since Jamal earns $400,000 and makes 67% of what starters make, then this can be written mathematically as:
67% of x = $400000
67% × x = $400,000
67/100 × x = $400,000
0.67 × x = $400,000
0.67x = $400,000
x = $400,000 / 0.67
x = $597014.93
x = $597015
His next salary will be $597015

I hope this helps!
Explanation:
Technician A states that a pressure bleeder may be needed to bleed EBC system hydraulic circuits. Technician B states that once the scan tool indicates that the HCU is bled, it may direct you to bleed the brakes manually to remove any remaining air from the system. Who is correct
Answer:
Both Technician A and Technician B
Explanation:
ABS modulators such as the Ford EBC310 version which are not equipped with bleeders are to have there valves cycled and their pumps activated to enable the bleeding out areas which are not easily bled by the wheel based bleeding
The brakes can be either pressure bled or bled manually, however, the HCU will require additional processes to completely bleed out the system, such as the use of a scan tool

A method used to control density and overcrowding by restricting setbacks, building height, or ratio of open area is known as _________ zoning.
Answer:
Bulk zoning.
Explanation:
Zoning is a method used by municipal authorities or government authorities to divide a land area into zones. It is a urban planning method. There are several types of zoning; bulk zoning being one of them.
Bulk zoning can be defined as a set of regulations used to control lot size, ratio of floor area, open space, yards, setbacks, bulding height, etc. These setbacks and restrictions, then, help authorities to determine maximun size of a building on a zoning area, and also the positioning of the building.
Therefore, bulk zoning is the correct answer.
where has the process of nuclear fusion been occurring for over four billion years
Answer:
Inside the Sun.
Explanation:
Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium. This fusion process occurs inside the core of the Sun, and the transformation results in a release of energy that keeps the sun hot.

Which option best characterizes Reese's choice of less-than-optimal materials in the following scenario?
Reese has just designed a vándshield for an extremely lightweidot car that can be transported by the military via helicopter. The engineers
wanted to use a specially formulated glass that is lighter than ordinary glass, but the cost was far above the budgeted amount for the
project's materials. Reese decides to use a plastic windshield instead.
Economic considerations should never be placed above safety when designing a model
Economic considerations can endanger the safety of a model.
Economic considerations must be considered vihen designing a model
Economic considerations are the most important factor vihen designing a model
Answer:
Economic considerations must be considered when designing a model.
Explanation:
The engineers wanted to use a specially formulated glass which was lighter than ordinary glass for the design requirement of light weight and portability with helicopter. However the cost was very high than the budgeted amount for the material to be used in the project. The alternative was to use a plastic wind shield. In design perspective considering the weight and portability criteria, this will still work .In the economic perspective, the budget will fit. This concludes that economic considerations must be considered when designing a model. Though this factor might not be the most important one , but it helps in ensuring projects budgets are within expected margins.

Let f(z) = (4z ² + 2z) / (2z ² - 3z + 1).
First, carry out the division:
f(z) = 2 + (8z - 2) / (2z ² - 3z + 1)
Observe that
2z ² - 3z + 1 = (2z - 1) (z - 1)
so you can separate the rational part of f(z) into partial fractions. We have
(8z - 2) / (2z ² - 3z + 1) = a / (2z - 1) + b / (z - 1)
8z - 2 = a (z - 1) + b (2z - 1)
8z - 2 = (a + 2b) z - (a + b)
so that a + 2b = 8 and a + b = 2, yielding a = -4 and b = 6.
So we have
f(z) = 2 - 4 / (2z - 1) + 6 / (z - 1)
or
f(z) = 2 - (2/z) (1 / (1 - 1/(2z))) + (6/z) (1 / (1 - 1/z))
Recall that for |z| < 1, we have
[tex]\displaystyle\frac1{1-z}=\sum_{n=0}^\infty z^n[/tex]
Replace z with 1/z to get
[tex]\displaystyle\frac1{1-\frac1z}=\sum_{n=0}^\infty z^{-n}[/tex]
so that by substitution, we can write
[tex]\displaystyle f(z) = 2 - \frac2z \sum_{n=0}^\infty (2z)^{-n} + \frac6z \sum_{n=0}^\infty z^{-n}[/tex]
Now condense f(z) into one series:
[tex]\displaystyle f(z) = 2 - \sum_{n=0}^\infty 2^{-n+1} z^{-(n+1)} + 6 \sum_{n=0}^\infty z^{-n-1}[/tex]
[tex]\displaystyle f(z) = 2 - \sum_{n=0}^\infty \left(6+2^{-n+1}\right) z^{-(n+1)}[/tex]
[tex]\displaystyle f(z) = 2 - \sum_{n=1}^\infty \left(6+2^{-(n-1)+1}\right) z^{-n}[/tex]
[tex]\displaystyle f(z) = 2 - \sum_{n=1}^\infty \left(6+2^{2-n}\right) z^{-n}[/tex]
So, the inverse Z transform of f(z) is [tex]\boxed{6+2^{2-n}}[/tex].
