It's not the height it's the area of the foot on the ground.

I.e. total weight divided by contact area will give you the ground pressure.

A quick measurement says that the thing is 88mm tall (on the screen) and the foot is 0.5 mm diameter.

So that means that the foot is (0.5/88) x 2000 = ~11.4m dia = 102 m

^{2}.

Can't decide if there's 5 or 6 legs, but say 6 = 612 m

^{2}.

That's ~49,000 tonnes/ m

^{2} = 480,526,000 N/m

^{2} = 480 MPa.

That's enough to seriously damage steel.

Even worse is that to

*shear* through steel is dependent on the edge length of the feet (circumference of 1 foot is ~35.8 m so six feet gives 214.8 m).

From memory (and it's definitely a long-term memory since it's an Imperial value!) [mild] steel requires 22 tons/ sq. inch to punch holes in it.

So, with a bit of juggling we determine that if this thing walked on steel it's capable of punching holes straight through a "surface" (i.e. plate) that's 12773.6 inches thick.

That's 0.2 of a MILE!
