Partial Question 9 Which choices are correct explanations about the scanning electron microscope (SEM)? (Select all that apply.) Visible light is the main light source. The microscope can investigate non conductive samples as good as the conductive ones. Samples need to be polished. The condensed beam does not pass through the specimen, but is reflected from a surface of the specimen and was collected to obtain the picture. Useful resolution range is much wider than the optical microscopes.

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 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).
