MSE 23000 Homework Assignment – Week 13 (10 pts)
Thermal Properties Over the next week, think about the following problems and provide your responses as prompted below using this
document as a template
. Responses can be typed and/or inserted as scans or images (
e.g.
, of hand-written calculations or sketches). These questions are reflective of typical exam questions – hence, the students who complete their homework assignments are the best prepared for their upcoming exams. Additionally, you are encouraged to attempt all homework problems before attending your weekly recitation
so that you are prepared to ask questions and seek guidance & hints from your recitation instructor. This assignment is worth 10 points and will be graded for completion only. Submit your assignment as a single PDF document
by using the appropriate link on Brightspace.
(2 pts) 1. Callister 19.1: Estimate the energy required to raise the temperature of 6 kg of the following materials from 40 to 200°C: aluminum, steel, soda-lime glass, and high-density polyethylene. (1 pt) 2. Callister 19.7: An aluminum wire 20 m long is cooled from 30 to -6°C. How much change in length will it experience?
(1 pt) 3. Callister 19.9: Briefly explain thermal expansion using the potential-energy-versus-interatomic-spacing
curve.
(4 pts) 4. Callister 19.14: Multi-step problem about Thermal Conductivity
a)
Calculate the heat flux through a sheet of steel 10 mm thick if the temperatures of the two faces of the sheet are 400 and 200°C; assume steady-state heat flow.
b)
What is the heat loss per hour if the area of the sheet is 0.55 m
2
?
c)
What will be the heat loss per hour if soda-lime glass is used instead of steel?
d)
Calculate the heat loss per hour if steel is used and the thickness is increased to 60 mm.
(2 pts) 5. Callister 19.D1: Railroad tracks made of 1025 steel are to be laid during the time of year when the temperature averages 10°C (50°F). If a joint space of 8.7 mm is allowed between the standard 13.5-m long steel
rails, what is the hottest possible temperature than can be tolerated without the introduction of thermal stresses?

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.

Two sport utility vehicles (SUVs) are being considered by a recent engineering graduate. Using the following data evaluate which sport utility vehicle is better. Use six attributes in your a
point, overall appearance, comfort, safety, reliability, and fuel mileage. Larger scores on overall appearance, comfort, safety, reliability, and fuel mileage are preferred to smaller ones.
Click the icon to view the table with data you have gathered about the SUVs.
Determine attribute weights and use the nondimensional scaling technique to find the resulting set of vehicle scores. Fill in the table below. (Round to two decimal places.)
