Egg Impact Crash Test
My project was constructed by using simple materials that could be found around the house and were transformed into a protective device for two Grade A Large Eggs. The materials of my project are cardboard, tape and a hot glue gun. I used a cardboard box whose flaps folded in over top, but taped open the flaps so that the height would meet the 20 cm minimum requirement. I made sure the width was less than 50 cm so that the bumpers would not exceed the maximum. I then cut pieces of cardboard equal to the length of the long and short sides of the box. I loosely rolled each piece of cardboard and taped them so that they would not roll open. Next, on the long sides of the box I taped the rolls of cardboard to the box horizontally and on the short sides I taped them vertically. I applied a lot of tape to make sure they would be held in place during the crashes. To keep the eggs from rolling around the big box, I secured them in two smaller boxes. I secured the eggs in the smaller boxes by rolling a piece of cardboard about an inch in width around the egg to create a holder. The egg can easily slide in out of the holder, but not easily enough to fall out once a force is applied. I taped the holder to smaller squares of cardboard and taped them down to the bottom of the smaller box. Each small box had the same construction. Finally, to secure the smaller boxes in the big box, I hot glued them down in the center of the box. When assigned the project of creating a device to secure eggs in a collision with a pendulum at increasing velocities, I immediately thought of a car crash. Cars must be built that so that they will protect the passengers during any type of collision, like my project must be built to protect the eggs. Upon this thinking I decided to design my egg crash project like the design of a car. I would create an inelastic collision between the pendulum and project, meaning
