This is what is being used in smart munitions now. Survives well over
15,000 Gs.

I saw this in the
"For comparison, dropping a laptop produces a shock of about 2 to 4 g's. "

Where did they come up with that nonsense?


U B Idiot. A drop from 3 feet up generates about 3 to 4 G's.
Square wave, sudden stop. A typical Hard Drive at rest can handle
40Gs.

Maybe by dropping it into a box
of styrofoam peanuts.


You ain't real bright.

Just dropping it a few inches on a hard surface is
many more G's than that.


You aren't very bright at all. Here's some figures for you to
utilize.

For only 14,000 G's, they must have crashed their
high-speed ordinance into something fairly soft.


14k was the limit of their test gear. The munitions get more, but the
MEMs still work! They saw 100kGs likely.

It's like the collapse of a flux wave on a transformer with DC on
it. Theoretically infinite voltage is induced, but we know it is
less, and less still with loading.

A drop to a sudden stop is theoretically infinite G force, but we
know that it gets dampened and is far less, depending on the
conditions involved.
