so cetrifugal force doesnt exist?
seriously?
are you retarded?
swing a ball on a string, and see if you feel a force.
release the string and what happens to the ball?
turbine blades do EXACTLY the same thing when they release themselves (in whole or in part) from their hubs and axles

note that melting point...
"The desire to produce a high engine efficiency demands a high turbine inlet temperature, but this causes problems as the turbine blades would be required to perform and survive long operating periods at temperatures above their melting point. These blades, while glowing red-hot, must be strong enough to carry the centrifugal loads due to rotation at high speed."

ZOMG!! looks like Stanford University recognizes centrifugal force, are they deceiving us?
is this part of some vast conspiracy to trick us into believing in magic?
or are you really that stupid
yes, they are lying to you.
aluminium is brittle. high
velocity rounds shatter aluminium into fine particles which can then catch fire.
http://www.g2mil.com/aluminum.htm
thin aluminium (like a pop can) yeilds to even a moderate force long before it can disintegrate, but why dont you go shoot an aluminium engine block and see how the hole looks (fine powderey particles a neat round hole, and a big ass crack running the length of the block)
cast aluminium, when it breaks clearly displays it's grainy structure (as any motorcyce mechanic can easily show you) and that grainy structure and low resistance to force is why nobody makes aluminium armor (that and the flamability, toxic fumes when burning, low resistance to corrosives, etc...)
"compressing" aluminium is not what happens when you shoot it, just like you can set dozens of bricks on a water glass without a problem, but one brick in motion turns that water glass to a pile of shattered fragments.
