2. In studying for your CBEMS 125B exam, you get hungry and decide to boil some water in a pot to make instant noodles. You put your aluminum spoon, with a long handle (i.e. good to use "long fin approximation"), in the pot in anticipation of stirring the noodles into the boiling water. However, your phone rings, and you leave the spoon in the boiling water on the stove for quite a while (i.e. the system reaches steady-state conditions) before you come back to it. The boiling water is at 100°C and room temperature is 25°C. The spoon has a square handle that is 0.6 cm per side. At a handle height of 8 cm, the temperature of the long aluminum spoon is 62°C. The Royal Society for the Prevention of Accidents lists a maximum surface temperature of 58°C as a "safe" touchable temperature for metals. Is the spoon safe to pick up at a handle height of 12 cm? Justify your answer with calculations. Assume (1) No radiation effect, (2) convection heat transfer coefficient is uniform in the pot…

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 Ti-6Al-4V…

I need parts 1, 2, and 3 answered pertaining to the print provided. NOTE: If you refuse to answers all 3 parts and insist on wasting my question, then just leave it for someone else to answer. I've never had an issue until recently one single tutor just refuses to even read the instructions of the question and just denies it for a false reasons or drags on 1 part into multiple parts for no reason.

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.   In talking with the workers, Jeff learns of some of…
