Introduction: The purpose of the Boomilever Project is to build a cantilevered truss that is light-weight while still able to support 15 kilograms. With this project it serves to reinforce the cumulative concepts that have been taught throughout this semester of Engineering Statics. It has been necessary to research designs, types of wood, and types of adhesive that will create a final result that is consistent with the desired result. Literature Review: The design concept behind a cantilever truss consists of a series of triangles joined together. The strength of these individual triangles, when combined, creates a very strong final result. Triangles are a very important part of many types of construction as they are the “only geometric figure that cannot be pulled or pushed out of shape without actually changing the length of one of its sides” (Bridges - Trusses, n.d.). As well as the advantage of the added strength, truss also do this without much additional weight. These concepts combined allow for trusses to be a very efficient way of adding strength. A cantilevered beam is what of which is supported on one end (usually a fixed support) and end is left hanging on the other end (Hibbeler, 2014). Cantilevered beams are able to support a load on the free-end. Cantilever trusses are popular in bridge and building architecture and possess many different uses. A cantilever truss with only a fixed end and a free end supporting a load and the negative y direction will translate the load across the supporting cantilever member and will thus have a positive y reaction at the fixed support since the sum of all reactions in a truss must equal zero (Hibbeler, 2014).
