The boomilever is a cantilevered wooden structure suspended from a wall that is used to support weight. It is one of the many competitions at the 2007 Science Olympiad. The name comes from a combination of the word "boom", like the end of a crane and the wordcantilever, which is a type of beam that is attached to a wall and has a load applied to the end.
Competition
The objective of the boomilever competition is to develop the lightest boomilever that will support the most mass. The structures are to be made of wood no wider than 1/4" and no taller than 1/4" . The boomilever will be attached to a wall with a 1/4" diameter bolt and a bucket will be hung from the far end of the boomilever by chain, into which sand will be poured. When the boomilever breaks, the sand in the bucket will be weighed. The score is determined by the structure's efficiency, or by dividing the amount of mass supported by the mass of the structure itself. The boomilever with the highest efficiency wins the competition. By competing in this event, students will hopefully develop their engineering skills and understanding of architecture.
