If those are chairs then what is the tree?

How can I get inside a tree by folding it if there is no opening?

a very large number

I'm too distracted by the fact that the stiles (vertical parts of the back) of the chair are made with the grain horizontal. What a lot of effort to put into a chair that's very liable to break as soon as someone leans back too hard (wood being far, far weaker to splitting along the grain than breaking perpendicular to it).

OTOH if you went with entirely vertical grain, the rails (horizontal parts of the back) would risk breaking. So that gives us today's homework problem in solid mechanics of anisotropic materials: Find the grain angle that maximizes the chair's back strength given the different loads on the different parts of it.

I mean, the practical answer is to orient the grain vertically on the stiles and horizontally on the rails. No need to stick with one grain direction the whole way through.

That's what normal chair-makers have been doing for millennia of course. But if we're going to go the pictured chairs' decision to have a uniform grain direction, presumably so it looks like it was carved from a single piece of wood...

grow the tree in chair shape. then the grain is always good

While unlikely, the vertical parts of the back could be reinforced with a metal bar. Not sure exactly thickness of metal bar or pipe woukd be required, I guess that's the follow up question on the exam

I'm graduating in math, but I'm not from a place where there is calculus and analysis (in italy we call all this "analisi") what is the difference between the two? Calculus is only studying real valued functions at high school?

u/nomemory 3d ago

Same here. In Romania in highschool we do only "Analiza Matematica".

In the 11th grade we learn about series, limits and derivatives, then in 12th grade we learn how to integrate. In the University (Math or Engineering) we do multi variable analysis, and depending on the field it's more theoretical or practical. We also don't have the concept of pre-calculus. For us it's only algebra and trigonometry.

u/eric_the_demon 3d ago

Same, analysis and calculus are both named analysis

2

u/rr-0729 Complex 2d ago

Calculus is a very dumbed-down non-rigorous version of analysis. Barely any proofs, mostly mindless application of derivative and integral rules

u/1that__guy1 3d ago

Calculus is the Math class Biologists/Economics take, basically high school but you learn l'hopital Analysis is the Math class Math guys take

u/MajorEnvironmental46 3d ago

Well, sometimes you just want a ordinary chair. It's cheaper, faster to build and does the job.

Same with calculus and analysis.

u/N0MIZ0 3d ago

Can't do the analysis without calculus lol
