 My first small step was taking agricultural building structures and learning about stress and structural analysis. My second small step was being a structural engineer for Cummins where I designed three engines. My third small step was leaving Cummins and working on a joint strike fighter jet doing a finite element analysis and then I started doing it for oil refineries and other companies. And last I came home and I built and designed barn dominions for people. I am Bob Malcolm. I am an agricultural and biological engineering graduated 78. I am a Purdue engineer.
