Aerogels can support 2000
times their own weight and depending on their composition they can
exceed an upwards of 5000 times its weight. Physicists are
experimenting with Aerogels in Kinetic energy absorption tests, that
one day might make Aerogels useful in vehicle safety devices. Its
energy absorption tests have seen positive results and further
experimentation with its properties are currently being carried out.
A 2.5 kg
brick is supported on top of a piece of aerogel weighing
only 2 grams. How much greater is the weight of the brick than that of
the Aerogel?
F=ma
a=9.81m/s
M=Brick=2.5kg
m= Aerogel=2g=.002kg
Fbrick=Ma=(2.5kg)(9.81m/s)=24.525
Faerogel exerted on the table=(M+m)a=(2.5kg)(.002kg)(9.81m/s)=24.54462
Faerogel*Alone*=ma=(.002kg)(9.81m/s)=.01962
Force of brick/Force of aerogel alone= Magnitude that Aerogel is supporting
24.525N/.01962N =1250
The Aerogel in this picture is supporting 1250 times its mass!
