Why when you compress materials like concrete do they fail in shear? Can the thing you're compressing be too small to fail in this way?

I had no idea Google did that! Thanks TT! :cool:

Thanks for the replies guys, much appreciated :wink:

Hi everyone, :smile: Apologies if this is in the wrong section, I'm still relatively new to the forum. :blushing: I'm an engineer studying Young's modulus in building materials. I have a passing interest in physics, but let's say my knowledge of the subject is far from exhaustive...

Hi, I've been looking for a good laymans book on Astronomy for ages now, but haven't been able to find one that isn't seriously heavy going on the physics front. I have plenty of astrophysics books, but not one dedicated to simple observational astronomy. Can anyone recommend a good, easy...

Hi guys, Thanks for your replies; I only wanted a quick rough idea of how to work this out so they were really helpful. Dadface, the furnace is an option but I wanted to work this out before commiting to anything. :) Thanks again guys. Fish

Hi, I want to electrically heat a uniform block of a known material to a high temperature (about 2000 K). I want to get a rough idea of how much electrical energy I need to supply to raise the material to this temperature so as to gauge what apparatus I will need. How would I go about this...
