Question 3You 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 hearingabout "osseointegration" in an exciting orthopaedic engineering class you attended at Clemson, so you plan to attach the footprosthesis 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 andimage below). You assume the tibial bone can be modeled as a hollow cylinder of cortical bone, as represented in the image. Youanticipate the length of the rod will be 1/2 the length of the tibia.Q3C-F: You decide to confirm the solid metal rod can endure the magnitudes of torque and displacement that can cause tibia bonefracture (Table 1).C-D: Calculate the minimum and maximum torsional shear stresses if those loading conditions were applied to the rod.E-F: Calculate the minimum and maximum torsional shear strains if those loading conditions were applied to the rod.

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.
