The box is in a room with air at approx. 25C. Do you know where I can find some derivations or how to begin? I havn´t studied thermodynamics, but maybe I can derive something if I just know the start of it and if there any special assumptions to be made. Thanks.

OK. This plate is a cover for a box so the temperature on the inside of the box is higher than 400C. I have a media (liquid) inside the box that I need to calculate the temperature on the inside of the plate that is on the box. 1. unknown. This is what I want an estimation of. 2. The...

Hello, I need some help in a matter. I don´t have any great knowledge in thermodynamics. If I have a plate of stainless steel (2mm thick). On one of the sides of the plate the temperature is 400C. I need to have a "simple" derivated calculation regarding how much the temperature is on...

Hello, I have a mounted specimen that I have etched. I need to make a calculation/estimation of the amount of ferrite in the sample. How do I do a simple analysis? Thank you

Thank you.

I understand a little bit. Should I do a equlibrium equation? F-R=0 in the horisontal direction? R being reaction force on the wall. I need some more assistance before I can go on. Thank you.

I´m sorry. The Force applied to the left in the figure can be neglected. It should be completely constrained in that position.

Hello, I need some help (or a lot) of calculating where and how much the maximum stress is in a plate as seen in my attached figure. It´s a thin plate (1mm) that is designed as my picture and it has two forces acting in opposite direction. How do I calculate where the maximum stresses...

ok. Thanks for the help. Ill check it out. Lets say it is water that becomes ice. Is there any easy way to derive an equation for predicting the increase in volume?

Hello! I need some help regarding a simple matter... How do I derive an equation for the increase in volume when a liquid goes to a solid state when I know the density of the liquid?

Thank you for your answer. I know it is fatigue, possible a combination of thermal and pressure fatigue. I would like to know if you could study the crack visually and make some conclusions. I know that you could see striations with a SEM and so on. I will check those books. Thanks

Hello! I am wondering if anyone could recommend som literature for me to get my hands on. If there is any literature regarding how the appereance of a crack in a piece of thin metal (~0,4mm - 1mm) could be related to pressure fatigue or thermal fatigue. Does the crack due to thermal fatigue...
