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…

please help solve A-F. thank you You are an engineer working on a project and your prototype has failed prematurely. You question whether or not a key component of the prototype was manufactured with the correct material. There are two way to check for the material properties. The first way is to have a material certification done to confirm the exact material composition. This will take some time. The second method to confirm the material properties is to make an ASTM test sample and test for the material properties. This tensile test was completed on a test sample with an initial diameter of .501” and an initial length of 2”. The Load-Deflection data for this tensile test is below. Use this data to answer the first set of questions on the Final Exam in eLearning. A. Determine the Ultimate Tensile Strength B. Determine the 0.2% Offset Yield Strength C. Determine the value of the Proportional Limit D. Determine the Modulus of Elasticity E. Determine the Strain at Yield F. Calculate %…

QUESTION 3 A Type I offshore life jacket (i.e. personal flotation device) is the type worn by commercial fishermen - it is designed for extended survival in rough, open seawater. Consider such a life jacket that uses an impermeable foam material with a density of 32 kg/m³ - the other parts of the life jacket (straps, fasteners, etc) weigh 0.6 kg and are of negligible volume to the design. a) Draw a free body force diagram for the life jacket. b) Determine the minimum volume of foam material (in L) that is needed for the life jacket in order to provide a minimum 98 N net upward force when it is fully submerged in seawater (as required by US Coast Guard regulations).

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…
