Some of you might've heard of this. It's a piece of software for designing simple bridges and testing them in a simulator which measures stress on individual components of the structure. It is aimed at novices that have no engineering background and it a great way to learn about some the work civil/structural engineers do. There's also an annual competition organized by the Westpoint military Academy in the US if you really get into it.
It's quite fun to mess around with and make the bridge collapse when the truck passes
