Task 1
You are employed as a mechanical engineer within an unnamed research center, specializing in the
development of innovative air conditioning systems. Your division is tasked with providing computer-based
modeling and design solutions using computational fluid dynamics through ANSYS software. Your primary
responsibilities involve the analysis of horizontal channel dynamics to meet specific criteria. Under the
guidance of your immediate supervisor, you have been assigned unique responsibilities within an ongoing
project. As a member of the research team, your role includes constructing an appropriate model and
executing a sequence of simulation iterations to explore and enhance channel performance. Figure 1
provides a visualization of the horizontal channel under consideration. Consider 2D, incompressible, steady
flow in a horizontal channel at a Reynolds number of 150. The schematic below illustrates the channel flow,
not drawn to scale. For simplicity, neglect gravity. The…

Task 1
You have been moved into the laboratory for the fluid testing for hydraulic devices and a considerable amount of research has been
carried out in an attempt to understand the exact nature of the temperature variation of viscosity. Inspect the table given below and
note the relative values of viscosity for each Newtonian fluid at a given temperature. Compare the results of a viscosity test and
comment on why the viscosity of ethanol and water is considerably lower than motor oil and explain any discrepancies.

Case Study – The New Engineer
Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator. This is Jeff's first position after completing his engineering degree. He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job.
Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace. They have never had an individual dedicated to this task full-time. They will implement his recommendations if he can justify them.
As Jeff begins to get familiar with the operations, he spends considerable time on the production floor. He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum. They also use this liquid to clean residue from their skin. They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke.

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…

Question 3
You are working on a design team at a small orthopaedic firm. Your team is starting to work on a lower limb
(foot-ankle) prosthesis for individuals who have undergone foot amputation (bone resection at the distal tibia). You remember hearing
about "osseointegration" in an exciting orthopaedic engineering class you attended at Clemson, so you plan to attach the foot
prosthesis using a solid metal rod inserted into the distal tibia. You think stainless steel or titanium alloy might be a useful rod material.
You decide to begin this problem by identifying typical tibial bone anatomy and mechanical behavior (as provided in the tables and
image below). You assume the tibial bone can be modeled as a hollow cylinder of cortical bone, as represented in the image. You
anticipate the length of the rod will be 1/2 the length of the tibia.
Q3G: Critical Thinking: What would you propose to your team as the next step in this analysis? Is it reasonable to assume the rod
will experience the…
