How do self supporting shelves work?

[Commander Kinsey]

How can these possibly stay up?

Ask yer wife. Same way she keeps her strapless evening gown up ;-)

It's obvious. There are steel rods deeply embedded in the wall and the shelves..

Neither of the 2 methods had anything embedded deeply in the walls - just ordinary screws into studs :

You'd think the weight of a full shelf of books would yank those screws out of even wood. Too much leverage, there needs to be a support lower down, like this:

That does not stay up if weight is applied by my foot. The perky nipples are not enough to keep it there.

"* These capacity ratings are based on evenly distributed loads. Keeping the load more toward the rear of the shelf will increase the capacity and decrease deflection."

"100 lb for a 4" deep shelf" seems optimistic unless you keep it very close to the wall so the loading is mostly in shear.

I grabbed 11 trade sized paperbacks off my shelf that looked approximately like the photo and they weighed 6.5 pounds so that is nowhere near to claim.

I wonder what shock load a cat can produce when launching from a shelf?

Are you saying my wife has steel rots deeply embedded in her chest!

I hope not. Please don't generalize from, perhaps, your wife. Quickly, please, take your wife to the orthopedist or blacksmith.
