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

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

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.

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 discuss a current business process in a specific industry. Note the following:

-The current business process itself.

-The industry the business process is utilized in.

After explaining the current situation, take the current learning from the course and:

• Explain a new technology that the business should deploy. Be specific, don’t only note the type of technology but the specific instance of technology. (For example, a type of technology is smart automation a specific type of automation is automated light-dimming technology).
• Note the pros and cons of the technology selected.
• Note various factors the business should consider prior to deploying the new technology

The above submission should be three pages in length. Remember the total length does not include the APA approved cover page or the references. There should be at least three APA approved references to support your work.

A 4-12 page paper covering the concepts and topics since the beginning of the course!

Each topic DOES NOT need its’ own section. For example, it may be easiest to talk about curvilinear motion in one section, or you may find it easier to separate curvilinear motion into two sections. Do what works best for you!

The paper should be single spaced, size 12 font, Times New Roman. You do not need to have a specific format for your reference section (if you use one), but you should include one if you are using outside references besides the class book.

Additionally, 1 example problem from the topics above should be included in the paper and explained in detail. That is 1 example problem in total!

Complete the following assignment in one MS word document:

Chapter 10 –discussion question #1-2 & exercise 1 & 7

Chapter 11- discussion question #1-4 & exercise 4

When submitting work, be sure to include an APA cover page and include at least two APA formatted references (and APA in-text citations) to support the work this week.

All work must be original (not copied from any source).

write about Automated biaxial strain device for microscopes.

1.Overall Objectives

Discuss the overall project (vs. the specifics of your approach)

Include brief discussion of any economic scenario your project is oriented towards (product commercialization, non-profit tech transfer, etc).

Explain what your team hopes to accomplish.

Highlights of Two brief examples:

Residents of urban areas experience increased street, basement and river flooding during small to mid-range storms due to excess impervious cover. Minimizing this flooding will increase safety and reduce economic loss.

Patients who take maintenance doses of medicine often forget to take their medicine at the prescribed time which can result in symptom flair ups and ineffective treatment.  Addressing this problem will minimize this risk and improve health outcomes.
