Alterations to Original Design

Added Jenga to cup


Cut portion out of backing


Added weight and momentum
Was creating drag
Switched to a larger screw

Gave hammer more room to swing
Energy Lost / Efficiency

When the hammer collides with the Egg


75.17212 ft-lbs
Our Efficiency

.75%
So as you can see, there are better
ways to crack an egg, but this has
a hammer involved !!
