I realized my error about the size-scale, but them being built like a Roman centurion in Asterix and Obelix especially the Emperor titans makes me wonder how they ain't toppling over. I mean a guy with the build of an Emperor Titan would be wheelchaired. Hehe wheelchair-titan would be cool to make.

Just thought about the structure of an Imperator Titan (the one with a flipping citadel on its head).

...

Yep. I agree with you. That thing should have fallen on its face about ten thousand years ago.

And create flesh eating viruses that act so fast as to violate the rules of microbiology, more or less figure out the physiology of the tyranids not long after meeting them, and engineer a plague to cripple a pyramid synapse web.

Magnetism isn't a mystery. It is very closely linked with how electric fields work and involves the spin moments of electrons; the strength of the magnetic field generated by a material depends on how many unpaired electrons the material has (as electrons existing in a pair have to spin opposite directions to each because of their quantum properties and thus their moment is cancelled out). Diamagnets (all material that is not generally considered magnetic) exhibit very weak magnetic behaviour because while it may not have unpaired electrons, the orbital moment of the electrons around the nucleus will cause a very weak magnetisation when you apply a magnetic field.

So do I, however it is never a bad thing to educate yourself. Especially in a subject people tell you is hard when it is actually pretty simple.

Well fair enough.

Giant walking robot's have a vulnerability to being tripped.

Ah the IOM is stupid-argument I love that. The IOM is struggling because it's so corrupt. A Primarch coming back would turn it around in an instance. Loves hearing about the rated stupid and superstitious IOM. Hehe, but I basically almost believes in the Machine Spirit existing IRL.

Some people in America have rickets, does that mean America's understanding of medicinal biology is poor?

No, it just means those people may have a lack of vitamin D. Or rigorous exercise.
But you'd think that after 40,000 years, the IOM would be good at this.

I just am curious how they don't collapse under their own weight and doesn't avoid stumbling.

Magic - and a little thing called "suspension of disbelief".
(SoD is what keeps the powers-that-be - ie, Physics - from raising its ugly head and saying "that isn't how it works!")

Hehe I kind of liked the willpower-idea. Too bad if it fails. *Princep loosing faith, and the Imperator behaving like a lethargic 90 yo suffering from epilepsy sprawling all over the dance-floor!* I would actually pay money to to see that, damn I must hate Titans with a passion.

Modern materials can build tower blocks 800m tall. The only thing we're lacking in the construction of giant stompy robots is an appropriately compact power source. the main reason we're not looking for such uses at this point is that we have guided missile technology allowing kneeseeker missiles to be constructed to counter giant stompy robots.

Are you still trying to apply real world physics to 40k? Have you not gotten the memo that a combination of greatly more advanced technology, literal magic being an integral part of the setting and rule of cool being law make trying to force the laws of reality on a setting that cannot function on said laws a really silly move? Titans just don't fall over that much, end of story, maybe they have some kind of magical gyroscopic stabilizers, but in the end they don't have stability issues.

Because we all know that if you believe in something hard enough, it becomes true

Assuming there is some fictional materials that allow them to be constructed, in the books and fluff the pilots and supports crew are plugged into MIU which basically controls the titan through cybernetics as if it were their own body. Think Avatar as opposed to say Gundam (well excluding G Gundam).

The problem is really more terrain centric, and I don't mean the house in the way, but ground requires an a disruption of weight to not just crash through so it seems far more likely that a titan walking would be like you walking through the mud; constantly stuck.

The Tau suits make sense in that they are smaller but have jump jets basically so they have controlled landings and ascents and isn't really a walking platform save to fire. IoM titans, however, just don't work from a physics standpoint unless they have some sort of gravity nullifier to help with that massive weight.

But hey this is 40k so rule of cool and all that.

Well, we know that the IOM did once have access to anti-grav. And to some extent still do. (HH hover bikes, Land Speeders, IOM spacecraft etc).

The IOM still can construct titans, just not the high-end ones. I mean the superstition of the tech-priests are in place for a reason. This is a setting where a soldier mishandling a lasgun can 10 years later have the malicious machine Spirit firing a burst into a commanding officer because you mishandled the gun once by dropping it. The Machine Spirits are scary vengeful things.

So there are suspensors, but you akso just need to get the right size of foot.

Typical bearing pressures for Earth terrain range from about 100kn/sq.m for soft silt up to about 600kN/sq.m for solid bedrock.

So for a 400 metric ton titan required foot sizes range from about 7x7m to 3x3m. This is about the mass of a fully laden heavy lift 747, so probably a reasonable guess for a knight or maybe a warhound at about 50m high.

For a 160 thousand metric tonne titan you would need 125x125m down to about 55x55m sized feet if it only ever tiptoed on granite. However, this is equivalent to the weight of a 240m tall, or 60 storey building with 50m to a side, so probably a bit unwieldy, even for a giant stompy robot. It would also need each foot to have a larger surface area than itself, but I'm sure it could be finessed.

So smaller titans would be easy while the larger titans would likely need some technosorcery assistance, which also has precedence in the fluff anyway.

I think the more interesting question is how does the thing even walk. The problem with bi-pedal robots is center of gravity. When standing still you would assume that the center of gravity is in the center of the robot. But once it picks up a foot, that center line must move to the center of the standing leg otherwise it topples over. Now that can be done with shifting weights. But with these things they have giant guns on their arms, swiveling torsos, etc., not to mention a stance tens to hundreds of meters wide. The three dimensional swinging counter balance necessary would be staggering.

This assumes 100% mechanical operation, and nothing like thrusters, anti-grav, or woogy woogy magic tech is in play. Because once you go all woogy woogy, all natural laws go right out the window.

The titans of the IOM is the tip of the iceberg, look at the Eldarish titans, they are freaking spindly. Though I admit I like the willpower-fueled titans that go belly up as soon as the willpower fails as that would please me mightily. Muhahahahaha.

It's interesting to see that essentially nobody in this thread has a clue what they're talking about....

Titan crew are categorically not psykers. The princeps, moderati and steersmen are connected in various physical ways, from MIU to levers and buttons.

Titans are incredibly sophisticated and possess rudimentary awareness - they take suggestions and commands from the crew and, to some extent, the titan carries them out.

They have incredibly complex balance and control system which keep them stable when standing, moving, fighting etc. They don't 'fall over in a breeze' nor are they 'spindly'.

They're multi megatonne war machines built by the finest the Imperium can offer.

Ork ones, however....

The Ork ones doesn't look like it would topple over, and actually seems semi-plausible.

It looks like a scrapheap, and has the mobility and structural integrity of one.

It's held together by spit, grot-tape and hope.

Yeah but they are the only ones I can see actually working in real life.

This isn't real life though. And why would you want it to be? Real life has a distinct lack of jetpacks and power armor.
