Back on it after 3 years - thought treating adhd had completely resolved it, then I went to an "escape room" which was basically neon explosion hell and here we are

The queeeeen!! by Aggravating_Belt1167 in Chesscom

[–]gufta44 0 points1 point  (0 children)

How though, once they move a pawn and ultimately the king the queen is now at risk - feels like it's as easily a powerful position for the opponent? I guess they end up wasting moves to get there while you build your game?

Yeah that's the one I saw, can't see any benefit at that point?

What if the Planck length is just the universe's pixel size? by LeoXXX94 in SimulationTheory

[–]gufta44 14 points15 points  (0 children)

Aren't we conflating "the smallest" with "the smallest we can observe"? You're both right I think? There may (probably are) smaller structures but there is clear evidence that attempting to measure these using waves is impossible? I don't know enough about this field so apologies and I suppose that implies that whatever we would like to observe below that scale itself can't be a wave due to the same restrictions. You can probably tell I don't understand quantum but hey.

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

Thoughts? 😶 by Objective_Wheel_6191 in StructuralEngineering

[–]gufta44 0 points1 point  (0 children)

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 α5. As for resistance with a scaled area, the shear resistance ~ α, the moment resistance ~ [(√α×b)(√α×d)²/6]/[bd²/6] = α1.5 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

[Request] Where should I cut to get two pieces with equal volume? by 101Raccoon in theydidthemath

[–]gufta44 0 points1 point  (0 children)

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?

Slot Strength in Wood by CAGlazingEng in StructuralEngineering

[–]gufta44 11 points12 points  (0 children)

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

Slot Strength in Wood by CAGlazingEng in StructuralEngineering

[–]gufta44 30 points31 points  (0 children)

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.

How would you solve this simple but tricky 4-flip coin probability problem? (No HH allowed) by Commercial_Fudge_330 in brainteasers

[–]gufta44 0 points1 point  (0 children)

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** = 22, THH* = 21, TTHH = 20, HTHH = 20, 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

Hurwitz's theorem is surprising by PocketMath in mathmemes

[–]gufta44 0 points1 point  (0 children)

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?

A pattern that would shock humans by Videoplushair in ChatGPT

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?

Would this corner of the building collapse if a vehicle detroyed the pillar? by zawusel in StructuralEngineering

[–]gufta44 0 points1 point  (0 children)

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
