Balsa Wood Bridge Senior Project, Ryan Moe
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 …

The Electrathon Vehicle: Electrical Power proposal is an in depth dive into theorizing, constructing and testing the design of an electrical circuit. A breakdown of this report gives an extensive and thorough analysis of the problem. How do you efficiently deliver 1kw/hr of power to an electric motor? The methods used to face this challenge and the results seen after are laid out in this report.
The challenge of competing in the Electrathon Race is delivering power to an electric motor for an entire hour without exceeding 1kW/hr of power. The goal is to travel as much distance in the …

Dual-Axis Solar Tracker, Alazone Smith
All Undergraduate Projects
The global energy crisis and continued supporting evidence of global climate change have begun to shift the world economies towards solutions that solve both challenges. Solar power has become one of the most recognizable and popularized renewable energy methods to date. In comparison to other photovoltaic systems, this project demonstrates the performance advantages of a dual-axis solar tracker. It also addressing its viability on a non-commercial scale. The objective was to improve upon previous solar tracker projects at Central Washington University by adding another axis to the system. This system implements both an actuator and a stepper motor to examine …
