Dang it! It's really buildable too! Like I don't have enough on my plate these days!

That actually works 

St Chamond + legs looks very insect like. Another pair of legs and you could have a War Beetle ?

And it probably wouldn't bog down when the nose of the tank is on a downslope, like the original

Nailed it!

Or the illustrated version could be the War Wombat!

From what I've been told about Wombats that could make it a very dangerous creature indeed

Yeah, it'd just bog-down the first time it hit soft ground.

Slightly off topic, but the issue of walking machines and soft ground explains why no AT-ATs on Tatooine.

Snow shoes! 

Seriously, though, has anyone tried calculating the ground pressure of the various sci-fi walkers? AT-ATs, AT-STs, Gundams, Labors, Mechs, Landmates, the spider tank from GitS.....

There's an idea for a Reddit thread if I were a Reddit user. That said, somebody has calculated the AT-AT to weigh 114 tons. The feet are roughly the size of an Snowspeeder which is about 5m square.

So: 25m2 x 4 = 100m2. Each foot is putting between 28 and 38 tonnes of pressure on the ground.
That means a very light PSI of 1.6 if all 4 feet are on the ground, and a 2.2PSI with 3 feet.

Feel free to check and correct my figures!

Do AT-ATs only ever lift one foot at a time or do they trot, canter, and gallop as required?

I just love this!!

The psi is fairly meaningless in this situation as it's still 25% of the total weight on each
foot when stationary, shifting up to 33+% on each of the planted feet when one is raised,
the weight on each foot is concentrated in a circle roughly 5m in diameter, and when the
AT-AT is moving it's a dynamic load not a static load which adds in another set of factors
as the load path moves past center. Most critically the load path is never straight down,
and the vehicle has overhangs to the front and rear, especially the front, which make the
load path even worse.

An AT-AT isn't a tracked vehicle which spreads the load in a different fashion, a load that
doesn't shift position while in motion and is always straight down through the centre of
mass.

I always regret having missed the days when Star Wars and Star Trek fans really duked it out, with higher numbers meaning advantage to own side... So, some guy somewhere, depending on leg thickness and various other issues, calculated the AT-AT to be something like 3000 tons. 3 zeros there. Misjudging the "compansators" the same set of people then went on calculate because of the way the Millennium Falcon reacted to a hit, a "flak" bolt from a turbolazer was the equivalent of 60 megatons. Making bigger guns to come at giga, tera and petaton range...

Someone was on drugs!

[tahsin]

Extremely involved calculations l must say. Millennium Falcon running away from Death Star and gots hit and it shudders somewhat and they are discussing how much do photons weigh, or some other particles to give such a momentum... Some others go a much simpler route and take the example of a Stardestroyer that simply wipes out an astreoid. Actually cheating out in that case by assuming it was just an iceball frozen solid. Because if it was iron, the results would have to be higher. I think all of them were made during the time about the Attack of the Clones.

[tahsin]

DON'T believe a word of it and divide by billions and trilions where ever necessary but turns out the fun has been kept alive... 98 megatons is a maximum Star Trek can manage by blowing up your beautiful Cruiser in a suicide mode but AT-AT maximum firepower varies between 16 to 130 kilotons... As established by taking measurements from each frame where they destroy the shield generator on Hoth and it seems there are indeed bigger terms than a peta something...
