Boomilever is a structural building event where the competitors design and build a boomilever prior to the competition, with the intention of supporting the most load with a small weight (i.e. maximize efficiency).
What makes a strong Boomilever?
Basic Design: It is generally accepted that the tension boomilever is inherently better than the compression. This is because the strength of wood in compression decreases per length unit the longer the piece of wood is. However, wood holds the same strength in tension no matter the length of the piece.
What is detector building Scioly?
Science Olympiad’s Div. C event, Detector Building, combines coding, engineering, math and science into a functional sensor that is calibrated and coded to collect data. During the competition, teams may adjust their code and calibration equation.
What are the different types of boomilevers?
Objective: To build a boomilever with the greatest efficiency. There are two basic types of boomilevers. First is the tension boomilever, where the tension chord is longer than the compression chord. Second there is the compression boomilever, which is the opposite of the tension.
How do I make a boomilever structure?
Start by modelling (building) your structure in SkyCiv Structural 3D (S3D). To do this, you can enter the node locations, or use the pen tool to draw out the nodes and members of your Boomilever structure. As an example, I will build mine in the x direction, then up in the y. A few things to remember here:
How do I support the boomilever on a 5 cm x 8 cm?
Since at the end of the boomilever, the loading block cannot be supported (as the loading block is 5 cm wide, and the boomilever is 8 cm), you can use a piece of balsa to bridge across that gap, so that the boomilever is supported there.
What are the most commonly used boomilever bridge designs?
These bridges utilize much of the same engineering that boomilevers will require in the compression. In the 2018-2019 season, two of the most commonly used designs were the designs shown in the above photo’s top left and bottom right – commonly called “tower chimney” and “two column” styled boomilevers, respectively.
