Catapult Optimization Tutorial

[sspoldi]

Hi Everyone,
Last year a lot of people inquired about the design and optimization of the electric catapult we used in Stronghold. Since the basic architecture shows up a lot (like in our hammer in 2014), I thought I would attempt to develop a description/tutorial that other teams could use to help their design process.

I've attached a tutorial PDF and an Excel spreadsheet that walks through the preliminary sizing and design we used to validate the concept. Please let me know if it helps, I will try to be more diligent about posting our optimization programs before the end of build season, so other teams can benefit (or at least share our misery!).

Full Disclosure: I wrote the spreadsheet using LibreOffice on my Linux laptop and exported to Excel format. Laura had no problems opening it up on her machine (Windows 10?), but if anyone has a problem, I'll convert it to real excel and post.

Thanks, see you all in about 3 weeks!

Cheers,
Steve.
