Jcati Carbon Fiber Recycler- Fiber Conveyance, Taylor Miller

All Undergraduate Projects

Sponsored by the Joint Center for Aerospace Technology Innovation (JCATI), this project stems from a partnership between Central Washington University’s Mechanical Engineering Technology program and The Boeing Company. The goal of this partnership was to create a device that repurposes carbon fiber from wing trimmings from the 777. The device features four different students’ projects including the crusher, shredder, oven heating system, and the fiber conveyance system; the focus of this project. The JCATI Carbon Fiber Recycler needed a device to transport material from the shredder to the oven to make for an easier, more seamless production process. To solve …

Balsa Wood Bridge Senior Project, Ryan Moe

All Undergraduate Projects

For all of human history, people have been working to increase efficiency. This project followed in that pursuit by forcing engineers to create a 400 mm long bridge out of only balsa wood and glue that could withstand over 20 kgs of force with the bridge weighing a maximum of only 85 grams. The bridge also needed to have a lifting mechanism to raise it 140 mm above the starting position.

To accomplish this task, a strong truss needed to be built. Balsa wood is strong in compression so a truss with more beams in compression was used. Statics was …

Rc Baja: Drivetrain And Steering, Mathew Morgan

All Undergraduate Projects

The RC Baja competition is a contest where undergraduate mechanical engineering students design, build, and compete against one another. The objective of this competition is to create the most efficient RC car possible. A gear train analysis was done and showed an 8:1 gear ratio would be the most efficient ratio due to the chosen motor having a higher torque output. Also, a stress analysis was done and showed that 2011 T3 aluminum passed the stress and weight criteria. These analyses ensured the RC Baja car was efficient. Most of the parts for the drivetrain and steering subassemblies were machined …

Truss Alignment Tool, Jason Hedin

All Undergraduate Projects

The purpose of this project is to follow the engineering process from start to finish, and create a fully functioning truss alignment tool that has been designed, constructed, and tested successfully. The first phase involves the design of the truss alignment tool. The main design requirements of the tool includes taking an input force of 60 pounds and outputting the 630 pounds of clamping force needed to realign a set of two stacked trusses and pull their bottom edges flush. The second phase involves the construction of the tool. This involves all machining processes associated with the cutting, shaping, and …
