For my materials science course, one of our exam questions is to come up with a question and answer itWe will be graded based on the difficulty of the question and the completeness of the answer.My question is.Why do metals typically have a much higher coefficient of thermal expansion when compared to ceramics?Please rate the DIFFICULTY of this question on a scale of 1-101 easy10 hardI have the answer to this question completedI just need to make sure it is not an quot;easy questionquot;.Lastly my exam is tomorrow, so I would appreciate as much help as I can get.Thank you everyone!
Do you have a Michaels, close to you? They have a lot of knowlegable women in this departmentJust askUsually, you would want something of a heavier weaveAnd to have a strong wooden handle to help as supportThe color choice is completely up to your own ideaGravitat.
I would suggest you practice in acrylic until you get the right pattern [take LOTS of notes]When it is right, you can make a new one in woolThat way all re-do's will be with the cheaper yarn and the final cozy will be in the wool.
I would go with an acrylic yarn for a couple of reasons - it's less expensive than wool, so being new to the craft, if you don't get it quite right at first, you've not wasted money on a really nice yarnAlso, because you're using it around coffee, you won't cry if and when it gets stained! I tend to go for the least expensive supplies when I'm starting out new at something, then work my way up to the higher quality supplies as I get better at it.
There is a superwash merino wool called Zara that I really loveIt's sportweight, which is slightly heavier than most sock yarns, but that means you can also use bigger needlesI made my first socks from a WWI Red Cross patternIf you google Red Cross sock knitting, it's easy to findIt's a very straighforward top-down pattern on size 3 dpn'sIf you use the Zara with this pattern, you'll come out with really great boot socksI also love self-striping wool sock yarn, which you can find just about everywhereI haven't tried Lion Brand Sock-Ease yet, but I've had very good results with other Lion Brand yarns and would definitely suggest it.
What you failed to mention is what level is this materials science courseI presume it's an introductory college course, in which case I would give this question a rating of 8, because one would have to thoroughly understand the connection between bond energies and coefficients of thermal expansion, and how bond energies differ between ceramics and metalsIn other words, if you can already answer this question in depth, then you're pretty well grounded in introductory materials science On the other hand, if this is for graduate studies, where one is expected to be familiar with this stuff, the rating should be downgraded to perhaps a 3For a high school class? That's a jokeNobody in American high schools these days can even understand this stuffEdit: Thanks for the updateI still think this question requires a comprehensive understanidng of materials to even answer, so I give it a 8 for someone just introduced to the subjectIt would be like asking first year calculus students to explain Stokes Theorem.
