Hydraulic Balsa Wood Rising Bridge, Kaitlyn Greenfield
Hydraulic Balsa Wood Rising Bridge, Kaitlyn Greenfield
All Undergraduate Projects
What is the solution to allowing tall vessels to navigate past a vehicle bridge that is less than 10 [ft] above the water? To answer this question, a balsa wood bridge was designed, constructed, and tested. The bridge needed to articulate by mechanical means, allow for travel through the bridge, and be able to withstand ample force while the main structure only being constructed of balsa wood and glue. The project was analyzed in sections. These sections include: the bridge structure and its members, the hydraulic lift, and the pins needed for the bridge and hydraulic lift to operate. The …

The need for hands-on and face-to-face experiences in the engineering classroom is very great. The equations, principles, and concepts can all be learned, but without the visual and tactile application, these don’t always sink in or become concrete. A small-scale tensile test machine was designed, sourced, manufactured, and tested for the purpose of being applied in classroom settings to provide this experience to engineering students. Extensive research was performed concerning tensile machines on the market, the essential elements of which are the load cell, grips, crosshead, extensometer, motor, and frame. The raw materials for the frame were purchased and drawings …

Feed Control: Composite Recycle, Rosy Perez
All Undergraduate Projects
The Boeing Company gave Central Washington University an opportunity for students to research and come up with an idea to reduce costs and landfill waste caused by the trimmings from the 777x composite wing pieces. The engineering and manufacturing for this project is about transporting composite material through to the delamination and chipper process. The delamination process uses a ram to press two claw shaped devices together that bends and deforms the material in opposite directions. The chipper process uses counter rotating saw blades spaced 1/8” apart to produce small shredded material. It is important for this newly designed feed …

Throughout the evolution of high performance racing, a large emphasis has been on reducing the weight of the vehicle in order to improve its performance. Over the years, new designs and materials have been introduced reducing weight in a variety of different locations. Comparing weight reduced in different areas has shown that some areas are more valuable to reduce than others are. Perhaps one of the most beneficial locations are the wheels. This is because the mass of the wheel is considered unsprung and rotational. Because of this, large improvements towards the reduction of wheel mass have been developed in …

Design Of A Uv Curing Cartridge For 3d Inkjet Printing, Richard Wiswell
Thinking Matters Symposium Archive
In printing multi-layer electronic circuits, each layer must be formed as a continuous pattern in high resolution from ink jetted liquid droplets and be in precise alignment with the other layers, precluding substrate removal for UV curing. This research seeks to determine the optimal method for in-situ UV curing of the ink jetted material in a single pass. The inkjet replacement cartridge designed for this purpose was constructed of aluminum, fit into the printer head assembly in good alignment with the other ink cartridges, and contained a UV LED for in-situ curing and a cooling fan to maintain safe operating …
