5 psi doesn't seem like much at all! I wonder if that's a pressure survivable by a human.

Likely depends on how many square inches of the human are covered, and where on the human they are located.

Surely not? The point of pressure is that it's constant per area, so no matter how much is covered, the pressure felt is still 5 psi.

No. Put 5psi on a 1 inch x 1 inch area of my hand and I will be okay.

Put 5psi on a 12 inch x 24 inch area of my torso, and I will be very much not okay.

I would love to see that first bulldozer at work. I'm a little amazed because snow becomes incredibly heavy and hard to move/push when it's packed. As the blade moves forward, that dozer will quickly have to use incredible force to move forward. I experienced this first-hand last summer when I was driving my old Land Rover across the country. I was solo, way up in the very remote Henry Mountains [1] of Utah, about to…

Keep in mind that bulldozers routinely shove other, equally dense, materials around.

To be fair, much denser materials. A cubic meter of ice (which is clearly heavier than snow) weights 1,000 Kg, any terrain/gravel/sand will weight between 1,600 and 2,000 Kg per cubic meter.

Sounds like you bottomed out. At that point ordinary vehicles no longer get traction from the wheels because they don't have enough weight on them, in addition to the fact that being caught in the snow means you need more traction to move. Treaded vehicles don't have this problem if the snow is reasonably compact or they have wide enough tracks to avoid sinking in, as do snowcats or snowmobiles.

No, in my case, the axle, steering, and bumper sank into the snow and were encased. The motor simply did not have enough torque to turn the wheels. To get out, I had to excavate the entire front of the truck and then dig out a path for the front wheels to roll backwards.

For arguments' sake, the whole human.

This kills the human (joking... I don't really know)

this is correct

But people are fine with Mount Fuji... Incidentally, most people are also fine dropping the "Mount" prefix for Everest, Kilimanjaro amongst others...

Mt Fuji works because of the historical context. There are plenty of words and loan words now that would be different if they were translated using best practices today. I for one am fine with dropping the Mt prefix. Most of the people mountains are named after are dead now so there is no need to disambiguate them. I have spent a lot of time thinking about this issue; signposts here translate e.g. 長良川 as Nagaragawa R…

I can see your point, but and maybe I'm being fastidious, but I Nagaragawa River also irritates me. It's only born of ignorance - no one calls it Mt Montblanc.

I get it - the original meaning of the word is as relevant to its name as is the combination of the words forming its proper noun. To the Japanese Fujiyama is Fujiyama, and so there goes an argument for transliterating the name. And as point out, good luck communicating with a local when you ask where the "Nagara" is.

But look at the converse: Loch Ness 尼斯湖nisihu in Chinese

ネス湖 nesuko in Japanese

Let's say an human with height 170cm and hip width of 85cm (these are between the averages men & women) gives a rectangular area of about 1.4 m^2; the head and legs aren't as wide as the hips, but this doesn't include the arms, so let's take it as a guess of the weight-bearing area for a prone or supine human. This area times 5 psi is more than 5,000 kg (more than 11,000 lbs). So yes, I think it would kill someone.
