2- A piece of muscle specimen has the initial length of 30mm and square cross section with original side of 12 mm was tested using a tensile test.

Question 1 You are working on a design team at a small orthopaedic firm. You have been asked to select a cobalt- chrome-molybdenum (CoCr) material that will not experience plastic deformation under a specific mechanical test, as follows... A tensile stress is applied along the long axis of a solid cylindrical rod that has a diameter of 10 mm. An applied load of some magnitude F produces a 7x10³ mm change in diameter (see figure below, original shape is blue, elongated shape is unshaded). Q1H: Provide a brief rationale based on calculations used to support your answer. That is, how would you explain the behavior of the "new alloy" material to your design team?

2) A biomedical company is planning to design a robotic arm from polymeric biomaterials based on their stress-strain curves. You as a bioengineer/researcher in this company, are requested to choose the best material from different biomaterials (A, B, C, D, E, and F) based on their mechanical properties. Express your opinion shortly on the following questions? a) Difference between A and C? b) Difference between B and D? c) Difference between F and E? d) What would be your recommendation for the robotic arm?

Yield strength, ultimate tensile strength, linear coefficient of thermal expansion, modulus of elasticity (E), proportional limit, and rupture strength are all examples of mechanical properties of engineering materials. O True False A non-destructive test is any examination of an object in any manner which will not impair the future usefulness of the object. Non-destructive tests include: magnetic-particle, impacting testing, radiography, eddy current, and fluorescent-penetrant. O True O False One way to make a metal stronger is to increase the metal's grain size. O True O False --- OL T A metal that has a crystalline structure is called amorphous. O True O False

1-8 Discussions Discuss or explain each of the followings: 3. Differentiate between the behaviors of metallic and non-metallic materials under tensile test. 4. Affect of prior history of plastic deformation on the shape and magnitude of the

In your summer internship, you are tasked with measuring the ultimate tensile strength of a material to determine if it meets your company’s (Superior Super Ships Inc) specification. Your boss is worried that the new low-cost supplier, Shoddy Alloys Inc, may not be reliable but it is the only way to source on-time the SS304 needed to make finishings for Jeff Bezos’ new yacht, the Black Pearl. You collect several load versus displacement curves, as illustrated below. The initial diameter of the round gauge section is 0.25 in. You also collect the instantaneous diameter of the specimen during the test using a laser. Using the provided data, calculate what is the ultimate tensile strength measured in this test?

When an external force acts on a body, the body tends to undergo some deformation. If the external force is removed and the body comes back to its origin shape and size, the body is known as elastic body. This property, by virtue of which certain materials return back to their original position after the removal of the external force, is called elasticity. We can explain these behaviours using following elastic constants. Young’s modulus or Modulus of elasticity (E) Shear modulus or Modulus of Rigidity (G) Bulk modulus (K) You are required to submit a report explaining these elastic constants and explaining the relations between these elastic constants. (You can use the relation with Poisson’s Ratio and get the relation between E, G and K.)

1- What is management engineering? Is it an engineering branch, is it a profession, or what? 2- Define your duties as a management engineer? Whyshould Corporation need a management engineer? What is it you offer for the Corporation? 3- Mehmet is a manufacturing engineer at a bicycle company. Part of his job is to inspect broken bikes and draw up design plans for their repairs. One day, Mehmet gets instructions from his supervisor to fix a bike with brake cables off. When Mehmet inspects the bike, he notíces that the cables are broken because they are made of low-quality material, He suspects that this bike is specialy designed and that the customer does not know which materials will be most suitable for brake cables. That's why Mehmet decides to use a more durable material for cables when preparing design plans for the repair of the bike. When Mehmet goes to fix the bike, he learns that the customer specifically wants the bike to be repaired, but that no aesthetic changes should be…

Brinell Hardness testing can be used for both ferrous and non-ferrous metals. The test for ferrous metals requires a 500 kilogram load for 30 seconds and the test for non-ferrous metals requires a 3,000 kilogram load for 15 seconds. True False   Please answer the photo question
