Multiple choice questions, please help thank you!! 1. The chemical potential (μ) of smaller size clusters is bigger than that of bigger size clusters because of  (a) their small size  (b) the fewer number of atoms in them (c) surface area is smaller (d) their surface is more curved 2. Which of these characteristics would you associate with SEM: A surface imaging tool Maintained under vacuum Provides imaging and compositional data Uses a scanned electron beam All of the above   3. Secondary electrons (SE) are best described as Low energy electrons from the sample surface  High energy electrons from the sample surface  Low energy primary beam electrons  High energy primary beam electrons 4. Atomic force microscopy (AFM) is the most widely used form of scanning probe microscopes for the characterization of nanomaterials since it require: (a) electrically conductive and optically transparent samples (b) neither electrically conductive nor optically transparent samples (c) electrically…

True/False 1. ____ Metals have long and thin bubbles in Strength-Modulus Chart because the processes used to manipulate their properties have almost no effect on the modulus but have a dramatic effect on strength. 2. ____ Cross-linking, blending and filling of polymers with particulates or fibers do not change their modulus or strength. 3. ____ The strength of ceramics depends on porosity, generally the higher the porosity, the higher the strength. 4. ____ Three basic ways to manipulate the mechanical properties of metals are: solution hardening, precipitation hardening, and work hardening. 5. ____ Foaming reduces density of metals, ceramics, and polymers but does not affect modulus. Your answer

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…
