Find an important engineering failure that involves some of the topics discussed in MSE 350. Describe the failure, why it occurred, the damage (human, environmental, and economic) and the changes that could have been made in the design to avoid the failure. Was the failure caused by lack of engineering knowledge at the time, engineering error, or management/government error? Discuss!!

For each of the following common items, identify what they are commonly made of, the material type (composite, metal, semiconductor, polymer , ceramic, glass. Describe why that material type is used. Include at least two references for your answers (websites are fine, but try and find good ones). If more than one material type is used in the items, include them all! Be careful to use proper engineering vocabulary when answering this question!

Automobiles Integrated circuits

Airplanes Bridges

Solar panels

Latex paint

Soda bottles

15) A spontaneous chemical reaction:

a) will never occur on its own

b) could occur on its own, but might take a long time

c) has to occur immediately

13) Disulfide bridges stabilize which of the following levels of protein structure?

a) primary

b) secondary

c) tertiary

d) all of the above

e) none of the above

d) has an overall positive free energy change (ΔG)

e) decreases entropy, according to the 2nd Law of Thermodynamics

14) In your research, you expose a culture of amoebae to mutating radiation and then isolate a mutant cell that is unable to move (it cannot crawl around), but otherwise grows, divides, and appears normal. You suspect that most likely, this cell has a mutation in a gene that encodes a protein involved in:

a) actin filament formation

b) microtubule formation

c) ribosome assembly

d) intermediate filament formation

e) DNA formation

2. Describe ASK, explain how it works and why we use it:

3. Explain what PCM does and how it works:

4. Which of the following networking device(s) block(s) broadcast traffic, thus dividing networks into separate subnets? (Hint: only OSI Network layer devices can divide networks into separate subnets): Routers, Switches, Wireless Access Points (bridges)

5. List the three types of multiplexing from the text and explain how they work:

. List two network layer protocols and explain what they do:

6. Explain what the acronym “ARQ” stands for and explain how it works:

7. The Session and Presentation layers are explicit layers in the OSI model, but are embedded within the Application layer of the TCP/IP protocol stack. Explain what the Session and Presentation layers do.

Session:    

Presentation:    

8. How does the application layer handle security?

You have been talking to a student from the engineering program at UBC who has also taken up temporary residence at the North Pole in between active semesters of her studies. Because of her engineering background, the elves have given her the nickname “Casey Jones”. Casey scoffs at the α = .05 significance level that psychologists use in their hypothesis testing procedure. She tells you “That means you will, in the long run, make an error one time in twenty. If engineers had an error rate like that think of all the buildings and bridges and such that would be falling down! Why don’t you psychologists be more like engineers and set your error rate to something like one in a million instead of one in twenty?” Explain to Casey Jones why, in the context in which psychologists use it, an alpha level of one in twenty makes more sense than an alpha level of one in a million.

Hoover Company signs a four month promissory note for $ 270,000 on January​ 31, 2016. The company is required to pay $ 67, 500 on the note each month. The first payment is on February​ 1, 2016, and the final payment is on May​ 1, 2016. How will this note be reported on the balance sheet at January​ 31, 2016?
