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…

Part II. Longer problem focused on problem solving multiple steps. This problem will be graded based on process, clarity of work, and correct answer and units. a. A spring is stretched, with a force, F = 442 lbf, along the outside of a pipe as shown with a = 53° and ẞ 69° and the coordinates of the force are (15,37,-71 ). How far does the spring stretch if the spring constant is k=67 lb/in? Hint: The force that stretches the spring is the projected force along the pipe F (x, y, z)
