It goes further than that. Young’s modulus does indeed determine the elasticity (springiness) of a material but don’t go ahead and think it’s only relevant for systems with moving parts that deform and go back into their original shape. Young’s modulus is literally at the very heart of every structural engineering calculation, static or dynamic.

The stiffness of any structure is determined (among others) by E*I, I being the second moment of area determined by the shape of an object and E being Young’s modulus of the material. The tension in any structure is also determined (among others) by (load)/E*I. So Young’s is proportionally responsible for an objects ability to resist deformation under force and inversely proportional for the stress inflicted to the material by those forces. Both deflection and stress are potential causes for failure. If your structure loses a significant amount of its structural rigidity, it might fail. If the stress in parts of your structure rises significantly, they might fail.

So steel may only melt at 1400C, but it has already lost half its load bearing capabilities at around 550C. Whether a structure collapses entirely is mostly a question of what factor of safety the engineers have applied when dimensioning the components. If the temperature was 550C (hypothetical, for this example) and the steel beams did indeed lose half of their ability to resist deformation by the loads they were bearing, and the tension in them did double, even a relatively high factor of safety of 2 ( i.e. everything is built twice as strong as it needs to be) would be the tipping point for catastrophic failure. In reality the factor of safety was probably lower, between 1.5 and 2.

That’s the whole point, what good would it be to compare equivalent vehicles, when people don’t drive equivalent vehicles? They drive bigger and heavier vehicles on average, negating efficiency gains of newer vehicles.

That would genuinely be so good.

Ha! Nice

This is such a miserable experience. The price was about the same, btw.

Tbh if it wasn’t for horrendous delays I’d still prefer a 14 hour night train over a 1.5 hour flight that in reality is usually a 5 hour test of my ability to kill time waiting. I’d rather get on at 8 pm, watch a movie, fall asleep, get up, have breakfast in the bistro car and get off at 10 am. Especially if it’s the same price. Usually night trains are considerably more expensive if you desire any kind of comfort or privacy.

You can’t transfer it entirely, could even crash your game from my friend’s experience. Best pick out your most important commands, put them in an autoexec.cfg for CS2, and see what works and which commands have become invalid.

And what is the problem with a gas hybrid heat pump? It’s an ideal solution for places that get very cold, use the gas furnace for the weeks when it’s below -5 and use the heat pump for many months around that. It’s one of the most efficient ways to use a heat pump as you don’t have to bully it through the coldest part of winter with very bad COPs, you’re only using it when it’s most efficient. And when your heating period is very long, that will only benefit your seasonal COP. So of course it’s more expensive than a simple furnace, but it will also save loads of energy and redeem itself after 5-10 years.

The best part about this is you already have an AC, aka a heat pump, but you don’t use it for heating?

Focus on doing what you can, not on thinking what to focus on.

Okay, I suppose you wouldn’t do that when replacing and old furnace but rather go for a hybrid system. In Europe loads of people are reacting to hiked gas prices and have perfectly fine furnaces in place that they don’t want to get rid of.

People think that’s a killer argument against heat pumps when it absolutely isn’t.

In that sort of climate you get a hybrid system or just leave your old furnace in as backup. You’ll use the furnace for the couple of days/weeks when it is below -25c/-13f and use the heat pump for the 6 months around that time window and save huge amounts of energy because you only use the heat pump when it’s most efficient. A hybrid system will improve efficiency because it combines the technologies at transition temps while just keeping the old furnace as backup is obviously much cheaper, since you can also get a smaller unit than you normally would because you don’t have to worry about the coldest period.

The number of registered cars has risen considerably, even in the last 10 years or so, and cars are getting increasingly bigger. IIRC registered cars in Berlin for instance has risen from 1.2 to 1.4 m in the last decade or so without the city expanding or gaining any meaningful parking space. Law enforcement is typically fundamentally carbrained, so they are lenient on such violations, thinking you can’t punish the poor people who have to park their car somewhere. With modern technologies it could be battled quite effectively, but it’s simply not politically desired in the Autoland. Instead, privacy and bureaucratic overload are made up as excuses on how it’s impossible to get a hold of it.

I think it goes past mildly on the concern scale. Car centricity in German cities already starkly reduces the quality of life there, and we still haven’t even collectively recognised it as a problem, instead it is still getting worse in 2023.
