How does one topple a pyramid?

Pushing very, veeery hard.

Last _{quite different from a food chain} Post

If you do not push at a point high enough this will not help at all.

How does one topple a pyramid?

Turn it upside down and give it a little push (a light tap is sufficient obviating the need for Zono's hefty expenditurre of energy).

Last Post

The turning upside down part would be the toppling. How do you achieve that?

You push a lever very hard to topple the pyramid on it's side.

What is the force to topple a 4 sided pyramid in relation to that needed for a cube of the same height and mass?

Last _{tricky question since one has first to calculate the geometry of the pyramid} Post

Edit: if my calculation is correct, then the pyramid has to get tilted almost 74° before it topples over while the cube topples already at 45°.

[Sibling Zono (anon1mat0)]

Depends on the slope of the pyramid.

Build the pyramid on a glacier?

For the given pyramid (even in volume/mass to a given cube) the slope is fixed (leading to the toppling angle I calculated).
Another thing that makes any pyramid more stable than the corresponding cuboid is that in the latter there is mass beyond the perpendicular balance plane the moment the tipping begins (any angle above 0) while in the pyramid this only occurs once the sloped face gets perpendicular (i.e. at 90°-slope angle).

Then you better slope off and leave  me with the Last Post.

[Sibling Zono (anon1mat0)]

But at this time of the year there is no snow in the slopes.

Or to the UAE with their indoor Alps

Last _{most wasteful guys in the world} Post

Alps built of sand are not ideal.

[Swatopluk]

Press the sand enough and it will become rock.

Last _{and I presume that those indoor ski slopes in Alpine format are mostly concrete} Post

Would you say that claim is set in stone?
