    5:39 isn’t one of the many values/points of an engineer is to size things appropriately? Wouldn’t need engineers if everything was stupid overbuilt (looking at you, Empire state building), but would also be way too expensive to build most things. I like how he breaks down rebar but kinda misses the point.

    Isn’t the numbering of rebar based on the diameter in 1/8th inch increments? So a #4 bar is 1/2 inch and a #9 bar is 1 1/8 inch diameter.

    Here’s my dilemma here’s my dilemma how come scientists haven’t created a way to start pumping groundwater back in when we’re having heavy rains and flooding pump the water back into the ground water systems to be able to utilize the Earth as a built-in Reservoir now that we’re starting to have additional rains why don’t we replenish our ground reservoirs underneath cities in States why can’t we pump the water back into the Earth if we can take it out we can put it back in

    What other options are there if you cannot deconstruct a building with explosives? For example, what if a building on Long Island needs to be taken down? Those skyscrapers seem to be awfully close to allow for explosives.

    Traffic signalization can also address issues of speeding (so you’ll hit more red lights if you drive higher than the speed limit) or are prioritizing other modes of transport, such as pedestrians, bike lane users, and buses (and so vehicle drivers will experience more red lights).

    8:00 Another explanation is, you’re just remembering the times you’re stopped at red light, and forgetting the times you run a green.

    Hitting red makes you feel inconvenienced, frustrated, and wronged. Hitting green elicits 0 emotion.

  74. Samuel Clark

    Great engineering knowledge and great explanation skill but a lot of these answers should’ve been directed at urban planners. The line for example, is significantly less efficient than a regular “hub and spoke” or circular design when considering transit. Building up is great, but building too far out always creates problems. He mentioned good reasons to not have elevated subways in NYC, but a reason he missed is the impact of all that above ground infrastructure on the already very narrow streets.

    He worked at the university I went to and talked to my freshman class a few times. If I’m not mistaken he judged a competition we had and I was the third place winner. I got my engineering degree but am not using it. Glad someone as smart and nice as Nehemiah is though.

    Why would you ask a structural engineer about urban design? Completely different disciplines.

  82. John Scaramis

    March 10, 2023 at 4:24 am

    6:04 Concrete’s compressive strength is higher than is quasi-nonexisting tensile strength. However the compressive strength of concrete is still much smaller than that of steel (however there are some high-tech concrete variants that can reach the strength of mild steel).
    Then why use concrete? Because the ratio of costs to strength is much lower for concrete compared to steel. And it’ easier to pour concrete and make planar substructures 😉

    10:52 I’ve been regurlarly working in Dubai for the last years. No drainage at all. For the short rainfalls here and there this is OK. But if the rainfall lasts a few days (which happened a few years ago), life becomes complicated, as nobody is prepared for such amounts of rain

    This guy has not watched “not just bikes”
    Actually he might have, but the editor did not.
    He is correct naming Amsterdam, but like 9 1-word cuts later he’s talking about canals.
    The reason Amsterdam is such a good design, is because it prioritizes pedestrian and bike traffic, not motorized vehicles. That might be due to canals in a round-about way, but its not because “canals.”

    A lot of math also goes into designing a bridge for wind and variable load conditions. Two examples where the engineers fell down were the wibbly wobbly London Millennium Footbridge and the 1940 Tacoma Narrows Bridge, and we still have bridges where soldiers are advised to “break step” when crossing them to avoid resonances.

    What is the civil engineer plan for the very near future for our cities, say 2030s-2090s?
    Do you support the abolishment of cars? If so, what is the plan for giving the people back their land, all the land ceded to car and oil companies?

    There is only about 3 billion EVs’ worth of mineable lithium reserves, so unless the plan is to simply return to fossil fuels by the end of just this century, surely there is some plan to revert our city design back to before we let capitalists turn all our roads into death traps and 50% of open space into parking lots.

    Or is that just a problem we leave for our grandchildren?

    Can conform a whole lot of maths is involved. At schoold I had a class called dimensioning of structures, where we were taught how to dimension structures, considering the different forces applied on it (wind, its own weight, cars,…). It was a NIGHTMARE of calculations. Maths everywhere. Yikes.

    the one about above or under ground for NYC trains, it really depends, even with weather bc the amount of times routes were affected by a flood, it is ridiculous

    Wait, you’re a civil structural engineer?
    I really hope there’s not that many uncivil structural engineers; that’d be uncomfortable.

    I loved Dr.Mabry’s video (‘Every Bridge for Every Situation’) for WIRED a couple of years ago, that and PolyBridge reignited an old interest in civil engineering – nice to see him back!
