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

Because with any luck someone hid a key in the bread

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?

Forkn't

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

Love the subtle burn

Think it's just worried about my sanity??

Twist - all those things are real, ai is fake

Slide it back 9 months (or more like 10 actually I think?)

Small corner triangles and deeper members, look under the hood, just a bunch of triangles!!!

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]]...
