2023_Student Test Results and Submission for Tensile Properties of Materials

Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the…

Select All the correct statements from below.  a. If the averaged distance between partial dislocations for material A observed under TEM is smaller than material B, the estimated stacking fault energy of material A is lower than material B. b. K_IC is a material property that doesn't change with testing conditions c. The main difference between high cycle fatigue and low cycle fatigue is the difference in the number of cycles to failure d. A negative R value in fatigue test indicate the minimum stress is compressive in nature

Kindly do not re-submit your answers if you have solved the problems in this post. I post multiple questions of the same type to get an idea from other tutors. Thank you, Tutor! S.1   Statics of Rigid Bodies Content Covered: - Method of Joints Direction: Create 1 problem based on the topic "Method of Joints" and then solve them with a complete solution. In return, I will give you a good rating. Thank you so much! Note: Please bear in mind to create 1 problem based on the topic "Method of Joints." Be careful with the calculations in the problem. Kindly double check the solution and answer if there is a deficiency. And also, box the final answer. Thank you so much!

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?

Match the following statements with the term that best describes each statement. (Enter Number ONLY) 1) Hooke's Law 2) Creep 3) Impact Strength 4) Proportional Limit 5) Fatigue 6) Elastic The tendency of a solid material to move slowly or deform permanently under the influence of mechanical stresses below the yield strength of the material. The behavior of materials that deform when loaded but return to their original shape after the load is removed. The linear relationship between stress and strain in the elastic region below the proportional limit. The phenomenon where cracks propagate under loads less than the yield stress due to cyclic loading. The material property determined using the Charpy or Izod test. The point at which the stress vs strain becomes non-linear in an elastic material,
