Title: So I found the stress that will be induced on my robot's chassis...
Post by: MaltiK on February 21, 2009, 06:23:16 AM

...how do I implement that into finding suitable material for building the chassis?

 You have done the hard bit. Now all you have to do is pick a matertial with a tensile strength great than the stress that will be induced in it. I'd recommend you work in a factor of safety of a least 2

Go to http://www.matweb.com/ (http://www.matweb.com/) and you can search materials and find their material properties,  including tensile strength.

Hope this helps  :)

Hmmmm but you can't calculate stress unless you already know the materials properties and dimensions . . . do you actually mean forces?
