A useful reminder that LEGO is actually a set of injection moulded parts with extremely fine tolerance, such that even the printing must be taken into account. It looks like they've run some of those models through finite element analysis software to calculate the force too.

Some of my mechanical engineering friends think of working at LEGO the way others think of working at Space X or NASA. I’m pretty sure all of those models have run through finite element analysis.

Stupidly tight tolerances, tons of computer analysis, modular parts and making things out of plastic are a fresh out of school ME's wet dream.

It takes age and experience to develop a taste for making things that are loose and cheap but through creativity of design still somehow manage to do the job.
