Cracking Humpty Dumpty Emilee Baldwin Patricia Eimer Raymond Stocker Aaron Lyda

Supplies… Plywood 3 screws 3 Jenga blocks 1 Styrofoam cup Fishing line Empty Playdo can with 5.50 in dimes A hammer 1 sad egg A funnel A bowl

Diagram Overview Kinetic Energy of rope pulling hammer Energy Loss of perfectly inelastic collision Kinetic Energy of trigger Gravitational Energy of falling weight Gravitational Energy of the domino fall Kinetic Energy of rope pulling out board Gravitational Energy of the cup falling

Alterations to Original Design Added Jenga to cup Added weight and momentum Cut portion out of backing 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 !!
