Write one paragraph of annotations notes for “The One-Handed Girl”. This should be a paragraph of 5-7 sentences, noting what you liked about the story, what you didn’t like, any observations you made or new things you learned, and an idea of how you might focus a literary analysis paper, should you choose to write about this fairy tale.
It is known that the yield strength of an iron is related to grain diameter as shown in the table. Determine the grain diameter that would have yieldstrength of 205 MPa.Grain Diameter (mm)Yield Strength (MPa)5 x 1021358 x 103260
2.(a) What is the approximate ductility (%EL) of a brass that has yield strength of 275 MPa?(b) What is the approximate Brinellhardness of 1040 steel having yield strength of 690 MPa?Hint: refer to Figure 7.19 in the textbook.
3. (a) What is the maximum tensile load Pthat canbe applied without causing yielding of the material?(b)Indicate in the drawing where you expect cracks to initiate and the direction of crack propagation if an excessive load is applied. Yield strength of the material is 475 MPa.
4.While inspecting a machineusingx–ray, you found an internal crack of length 4 mmperpendicular to a stress in service. If the material has a plane–strain fracture toughness of 28mMPa, what is the limiting stress for a factor of safety of 1.
5? The geometric correctionfactor for this crack is 1.12. 5.A 12.5–mm–diameter cylindrical rod of 2014–T6 aluminum alloy is subjected to a repeated tension–compression load cycling along its axis. Computer the maximum and minimum loads (force) that can be applied to have a fatigue life of at least 1.0 x 107cycles. Assume a mean stress of 50 MPa. Hint: reference page 32 of lecture file 140305.
6.A flat plate is subjected to constant–amplitude uniaxial cyclic tensile and compressive stresses of 120 and 35 MPa, respectively. If the largest initial surface crack is 1.00 mm and the material has a plain–strain fracture toughness of 35 mMPa, estimate the fatigue life. The Paris equation, in MPa and m units, for the material is da/dN = (5.0 x 1012)(K)3.2.The geometriccorrection factor is 1.4.
7.A flat plate is subjected to constant–amplitude uniaxial cyclic tensile and compressive stresses of 120 and 35 MPa, respectively. Compute the critical internal crack length if the fatigue life must be a minimum of 0.7 x 106cycles. The maximum initial internal crack length is 0.8 mm. The Paris equation for the material is da/dN = (7.5 x 1013)(K)1.8in MPa and m units. The geometric correction factor is 1.12.
Write a 4-page (MLA style) Argumentative Essay on a specific technology and its effects on humanity. The technology chosen can either be harmful or beneficial. Provide evidence to back up your claim from 3-5 cited sources.
If the transition of production to Mexico creates net incremental value:
a. What additional opportunities should be explored to increase the potential net cash flow beyond the actions listed in the case?
b. What actions would you recommend to ensure success and/or mitigate risk factors?

Technology and Cost Containment
Post a cohesive response that addresses the following:
• Briefly summarize a significant challenge to containing health care costs. How do policy makers envision technology could be utilized to address this challenge? Provide at least one example to support your response.
Discuss Immigration and its connections to foreign policy
Approximately 30% of all college athletes are on some type of anabolic steroids.
Discuss the biochemistry and physiology of anabolic steroids.
How do anabolic steroids work? That is, how do they make muscles grow? Do muscle cells undergo mitotic cell division? What is the connection with cholesterol, testosterone, and estrogen? What is the difference between anabolic steroids and the steroids your doctor prescribes to you for inflammation? What is the problem with over-the-counter supplements like androstenedione? What are the side effects of steroid use? How are anabolic steroids linked to neoplastic disease? Do you think professional athletes should be tested for anabolic steroid use?
Be sure to reference scientific sources.
