(CBS News) While we like to have a lot of fun in terms of the content we highlight here at The Feed, every once in a while we need to take time to educate, too. And that time is now. So let's find out just how much pressure it takes to crush a concrete cylinder in this science video above. Do you want to try and take a guess? The results come in at about 1:40 into the clip.
I attended the University of Illinois Urbana-Champaign in March 2013 to give a talk about asteroid impacts. It was part of their very popular Engineering Open House day, which had lots of activities. One of these was crushing concrete cylinders with a mechanical press that can apply 3 *million* pounds of force. I figured the cylinder would just crack and crumble.
I was wrong.I would have guessed the same, honestly. But now the next time someone asks how much pressure it takes to crush a concrete cylinder, you've got a solid estimate. (Oh, and it was awesome to watch the cylinder explode, but concrete maintain, too!)
