Which option should the engineers focus on as they develop the train in the following scenario?
Richmond, Virginia, has recently approved the construction of a metro system throughout part of the city. As engineers study other
metro lines, they notice that there is an extreme amount of energy lost as the trains start and stop.
Engineers can design a train with additional valves to increase energy.
O Engineers can design a train with additional fluid pumps to increase efficiency
Engineers can design a train with a regenerative braking system.
Engineers can design a train involving larger hydraulic power systems.

Answers

Answer 1

Answer:

  Engineers can design a train with a regenerative braking system

Explanation:

Assuming the point of the question is that the engineers want to focus on using energy efficiently when starting and stopping, they would likely want to consider a regenerative braking system. Such a system can store energy during braking so that it can be used during starting, reducing the amount of energy that must be supplied by an outside power source.

I need to drop 10 V to feed an LED from a 12 V power supply. The resistor value is 490 Ω. How much of my battery power will be wasted in the resistor?

Answers

Answer:

P = 0.204 W

Explanation:

Given that,

Voltage drop is 10 V to feed an LED from a 12 V power supply. The resistor value is 490 Ω.

We need to find how much of my battery power will be wasted in the resistor. The power of a battery is given in terms of voltage and resistance is given by :

[tex]P=\dfrac{V^2}{R}[/tex]

V is the voltage drop to feed an LED

Putting all the values,

[tex]P=\dfrac{(10)^2}{490}\\\\P=0.204\ W[/tex]

So, 0.204 W of power will be wasted in the resistor.

Section views give a clear indication of interior views of an object or structure including hidden parts  or features which are not directly visible through convectional ways such as direct observation.

Vs = 9 V, I = 13.6 mA. What is R?

Answers

Answer:

661.7 ohm

Explanation:

The base formula for the solution is

[tex]i = \frac{v}{r} [/tex]

so the I is equal to V divided by R and so we can change the formula according to the given stats so we change it to

[tex]r = \frac{v}{i} [/tex]

just put the stats in V and I and you will get the answer, don forget to change the milliampere to ampere!!

When using a Drill Press the speed of the drill should be
O a. slowed to be neat and safe
b. made faster to finish quicker
c. left alone, the speed does not matter
d. adjusted based on the hardness of the material

Answers

The speed on most drill presses is adjusted by moving the drive belt from one pulley to another. In general, the smaller the pulley on the chuck axis, the faster it spins. A rule of thumb, as with any cutting operation, is that slower speeds are better for drilling metal, faster speeds for wood. So maybe D

Annie has been designing a new pool filter for pools of over 5,000 gallons. The prototype she designed works well, but only on pools of less than 3,000 gallons. Which statement explains why Annie is not frustrated?
A. Engineers still need to design filters for smaller pools; this prototype can be distributed to other clients.
B. Engineers work in a cyclical process; she can just begin a totally new project.
C. Engineers can always take an existing idea and expand on it.
D. Engineers will not allow failures to stop them; a previous failure can be a practical solution for a new problem.

Answers

Answer:

C. Engineers can always take an existing idea and expand on it.

Explanation:

Engineers are problem solvers. When they identify a challenge, they design solutions and test the ideas using a prototype. When the prototype performs the desired output, they go ahead to implement a full design. This is to say, they take the existing idea that works in certain parameters and expand it to fit the intended solution.

Answer choices A,B, and D are true but not correct because the issue of frustration is not indicated. They are true because they explain the general form of working of engineers which is: continuing designing everyday to solve new problems, the work done by engineers has stages and processes and finally because engineers seek to give solutions, failure is not failing but a new problem that needs a new idea as a solution.
