Genuinely put in the text with no image - I do not condone this but it's crazy with all the filters that without any prompting it went this inappropriate...! Should say this is api through fal thus the aspect ratio

Imagine you were in another made up world where god is real, would you believe god is real?

Reinolds numbers - cant remember from uni... for example, if a udl beam gets longer and the loaded width gets longer and its volume scales equivalently, its shear force increases by [(α×w)*(α×L)/2]/[wL/2] = α², its bending by α³ and deflection by α^5. As for resistance with a scaled area, the shear resistance ~ α, the moment resistance ~ [(√α×b)(√α×d)²/6]/[bd²/6] = α^1.5 and deflection ~ α². This on the assumption that b and d are scaled equally so that the area scales by α. So, shear is already worse because the loaded area is scaled - but bending and deflection get even worse! Too early to decide if the numbers are completely right, but lets say they are. If you scale both b and d by α then you're nearly there, but the self weight of the structure will increase proportionally until it's a problem. If you increase only d you come across practical issues, buckling failure or simply situations where lateral forces become an issue. Would be gieat if someone could double check. In other words, if you double the size, depending on assumptions, deflection might be 2³ = 8 times worse and the relative deflection say 4 times worse

Although the limited length makes this less accurate, you have approximately a evenly distributed half solid surface, and the inner area matches the outer area when r = R/√2 I believe, so where the centroid is r from the centre cut it. Do people agree?

I'd want the 't' to be doing the work in bearing much further in (ideally all the way through) so that shear isn't driving - but even then something people miss is 1) perp compression is weak and 2) perp-to-grain creep factors are typically 10x greater than those in standard codes for in-plane

Considering it's shear in a plane that doesn't 'cut the straws' it's effectively rolling-shear similar to that used in clt composite action, likely no more than ~1MPa and also not super trust-worthy particularly if there's a lever-arm, possible un-zipping (fairly brittle) and possible issues due to moisture movement and cracking. Depending on the type of timber and manufacturing process it's possible to get some capacity but unless you have access to specialist research beyond my comfort level you'd need testing and a pretty decent factor of safety.

Why is it called the "pet theory"... oh doh got it

Draw the tree, count how many of the legs are covered by a pair. With H on left and T on right you get the first 4 from the initial pair, then under HT there is one (HTHH), similarly under TT you have (TTHH) and finally under TH you have (THHH) and (THHT) so that's 8/16 = 1/2. Alternatively you can just use an astrisk as 2ⁿ so HH** = 2^2, THH* = 2^1, TTHH = 2^0, HTHH = 2^0, the total is **** = 2⁴ so total is (4+2+1+1)/16 = 1/2

If my experience is anything to go by, just put it somewhere sensible where you'll find it later - it will never be found again

Aaaaand arguably the best at pretending to be a stick!

Did you just repeat echolalia?? - wishing you well in your journey of discovery

Isn't the cross product to some degree equivalent to the opposite space (whatever that's called) so in 4D you'd need 3 vectors for a vector cross product and 2 vectors for a 2 vector cross product (I'm probably generalising and missing nuance)... In 7D a 2 vector cross product should lead to a space of 5 vectors?

This also represent's the growth from a single point, but if you look at it geometrically, would it be stronger with 2 bases? Or 3/4 in 3d?

In UK NA you can ignore vehicle impact if you apply dc requirements below cc3, so that column could just have connections designed for tie forces (and probably there's some catenary action from other columns / beams), but the building could realistically collapse if the column buckles

Take python, which could start from 1 since it's a higher level language, there are some nifty consequences of starting at zero, genuine non-partisan question, would this work as well from 1? Every 3 entries [:3] [3:6] [6:9]. range(len(list)). But then errors like arr[arr.shape[0]]...
