Hello everybody I am Christina, I am new to this forum and I could need some guides in an old exam question. The thing is that I have an old exam left to do. And I have on old exam to practice on/ an old exam. The thing is that I donâ€™t have the right answer to the question and I am a bit rust. I am a bit insecure in this question/the outcome. And need some other opinions other than my one. My professor has not answer me so I have to tur to other solutions. I am pretty sur that I have the 3 first slowed, Should Shoe minimum temperature change under transient heat exposure= Thermal conductivity Must be light and stiff= Young`s modulus Should not break when dropped= Fracture toughness Then on the rest I get a bit insecure, some that can give me an insight or something.
