The attached files are to be used to create an analysis based on fuel economy of modern automobiles. The Word document provides the description of what is to be completed and the Excel spreadsheet has the data for automobiles built since 2000. You are being asked to create, and interpret pivot charts around the provided data. You are asked to create 3 separate charts that provide different insights into the data, 2 of these are defined and the last one is for you to determine the visual you want.

I am stuck on questions 4, 5, and 6 only being able to complete around half of each part. I need help solving these questions. The questions are at the end of the chapter for Ch9 that I am attaching. I am attaching Ch8 as well because it may be useful for calculations.

I’m working on a report book page.

1. Read your Annex from front to back. The Annex is the 2 chapters that I attached before. Part IV and IVB as well.
   1. Give me a 1-page book report. What is a book report? Use the same criteria given to you in Middle School.

1. Design a circuit that implements the function, F(W,X,Y,Z) = ∑m(2,6,8,11,14) as a NOR-OR, 2-level gate array. Submit the schematic and a screenshot of a simulation verifying the output for the input 1001.

2. Design a circuit that uses multiplexors to perform 1’s complement on a 3-bit binary number. Assume overflow bits are lost. Submit your schematic and a screenshot of a simulation verifying the output for an input of 110.

3. Given four inputs, A,B,C,D, implement the following functions in a programmable array logic (PAL) circuit. Write the programming table and draw the circuit.

F1(A,B,C,D) = AB’ + A’C’D + CD

F2(A,B,C,D) = BCD + AD’

F3(A,B,C,D) = B’D + AD’ + AB’C’D + BCD

F4(A,B,C,D) = C+ AC’D’

4. A circuit that accepts two 1-bit binary inputs, A and B, adds A and B together and produces the outputs Sum and Carry is sometimes referred to as a “Half Adder”. Design a circuit that accepts inputs A, B and Opp and uses a multiplexor to select between a half-adder circuit (A+B) and a multiplier (A*B). Your outputs should be Sum and Carry. Submit two simulations of your Multisim schematic, one verifying the conditions A = 1, B = 1, Opp = 0 and the second verifying the conditions A = 0, B = 1, Opp = 1.

1. This progress report is to contain the improvements and all edits of Progress Report 1, and add the first draft version of the Methodology, and Results sections of the project. The Methodology for this design should include, at a minimum, the analysis procedure and methods used to design the improvements to the device. Down below the first progress report. and all other documents I sent for you before

I’m working on a engineering project and need guidance to help me learn.

A presentation about gas-oil ratio wells during production:

Definition, causes, effect on the production (problems), solution(how to avoid it). Around 8-10 minutes presentation. 

This week, we are reading an essay called “Shadow Scholar” by by Ed Dante (Authenticity 131). The essay details the career of a writer who composes papers for students who are unwilling or unable to do the work themselves. He essentially facilitates cheating. However, the essay is about more than the ethical implications of cheating. In many ways, it is a critique of higher education. Using specific evidence from the text, explain Dante’s take on higher education. What are the problems with education that allow his profession to exist? Your response should be 200+ words and your must respond to at least one of your peers posts to get full credit.

This is the lab activity

Well, you just read a lot of theory about the Wheatstone Bridge as well as stress and strain. How does it all relate?

As you read this, notice that I spell gauge as “gauge”. Professor Dowell spells it “gage”. You may see me alternate at times.

A strain gauge is a very tiny “paper” that is made up of small electrical wires bonded onto the paper. The little gold rectangle you see in the illustration below is a strain gauge. About 0.25 inches long. Those are two electrical wires coming out the left side.

The strain gauge is glued onto the specimen that’s being tested. It is also an electrical resistor. When the specimen is subjected to tension, the wires that make up the gauge are pulled, and therefore get “skinnier”. It follows that the resistance generated by the gauge increases. When the specimen is subjected to compression, the wires of the gauge get “fatter”, and the resistance generated decreases.

The strain gauge will form one branch of a Wheatstone Bridge, specifically, it will take the place of Resistor #3. The setup will also use a second strain gauge, which I call the “Dummy gauge”, and it is glued onto another piece of metal, however, that metal piece is not being subjected to any loadings. This forms Resistor #4. The circuit diagram you see below depicts all of this. Most of this circuitry is inside our strain indicator box, including Resistors #1 and #2.

As I just mentioned, the circuitry depicted in the illustration above is mostly contained inside our B.L.H. strain indicator box. In the illustration below, I show a photograph of the strain indicator box and point out the various parts of it. In the lower left hand corner of the box, you see the Two Arm Wheatstone Bridge, also known as the Half Bridge. The wires you see coming out of the bottom left of the diamond arrangement attach to the terminals of Resistor #3 and are attached to the strain gauge on the specimen. The wires you see coming out from the bottom right of the diamond arrangement attach to the terminals of Resistor #4 and are attached to the dummy strain gauge. The specimen itself is a cantilever beam.

Here is a drawing of the specimen itself, which includes all the relevant dimensions.

Here are the general steps that we follow to perform this portion of the lab activity.

1. Turn on the B.L.H. strain indicator box using the switch on the front.

2. Switch the Bridge Selector Switch to two arm.

3. Plug in the 120 ohm, gauge factor 2.08 dummy gauge on branch 4 of the Wheatstone Bridge.

4. Verify that the gauge factor knob is set to 2.08.

5. Plug in the tension strain gauge wires on branch 3 of the Wheatstone Bridge. Note that the tension gauge is on top of the beam.

6. Use the strain measurement wheel to center the needle on the balancing meter to the null position.

7. Write down the reading from the strain indicator window. This is the DATUM.

8. Place the load on the cantilever beam.

9. Use the strain measurement wheel to center the needle on the balancing meter to the null position.

10. Write down the reading from the strain indicator window. This is the reading WITH LOAD.

11. Calculate the strain by subtracting: STEP 10 – STEP 7. Note that the coarse knob settings cancel as long as it was not adjusted during the experiment.

12. Repeat steps 5 thru 11 for the compression strain gauge. Note that the compression gauge is on the bottom of the beam.

13. Upon finishing, remove the load.

14. Turn off the strain indicator box. And then I attached the lab template
