Center lift pontoon trailers have a high center of gravity, therefore have the potential for the pontoon and trailer to tip while cornering. There is need for a component to stabilize the pontoon on the trailer while towing. Different concepts of a support system were sketched to determine the best option. The characteristics that were deemed important for the support system were narrowed down to determine the best concept and the connections of the best design were sketched in greater detail. The forces that the support system would have to withstand to stabilize the pontoon on the trailer were calculated. …

Recumbent Bicycle Balancing Aid, James Hager
Williams Honors College, Honors Research Projects
For our senior design project, our team will be consulting to create a balancing aid system intended for the recumbent bicycle shown below in Figure 1. The owner of the bicycle is Robert Henderson, a former United States Navy sailor from Northeast Ohio who picked up biking and skiing while he was stationed in Maine in the late 80’s. While there, he took to the mountains on the rugged terrain and brought this passion of biking back home to share with his wife, Johanna once he completed his service to his country. Biking became an integral part of the …

Using ceramic matrix composites (CMCs) for high-temperature applications in jet engines increases durability and reduces weight and cooling requirements resulting in improved efficiency and fuel savings. Understanding, detecting, and monitoring different types of damage is essential to achieve optimal performance of CMC components. The Direct Current Potential Drop (DCPD) method is a non-destructive technique of estimating damage in composite materials.
DCPD technique works by measuring nodal potential differences when current is flown through the material. Direct current spreading in different woven and laminate composites is modeled to follow a ladder resistor network in which the nodal voltages decrease exponentially as …

Fluid Power Vehicle Competition, Madison Graham, Wayne Ritchie, Emily Dicks, Ariana Cupello
Williams Honors College, Honors Research Projects
Our senior design project for the Honors College and the Department of Mechanical Engineering was to design a fluid powered vehicle. Our design was tested in an official capacity against other universities’ vehicles at the Fluid Powered Vehicle Challenge hosted and funded by the National Fluid Power Association (NFPA) and its industry partners. This competition had six different evaluations for our vehicle design; three race events, midway presentation, final presentation, and safety inspection. The three different race events were the sprint race, the efficiency race, and the endurance race. The sprint race was a 475 feet speed test, the efficiency …

“Aeroponics” is a plant cultivation technique where roots hang suspended in the air while the nutrient solution is delivered in the form of a fine mist. NASA has done experiments in space and found out that plants grow very well with aeroponic technology. However, “Hydroponics” is the most preferred method, where plants are grown in a non-soil medium, and mostly in nutrient liquid that flows through rectangular channels. There are advantages and disadvantages to each system. With the intention of combining the efficiency of aeroponics and the compactness of hydroponics, a hydro-aeroponic system was created to grow spinach and lettuce. …
Laser Ablation Of Aluminum, Erika Nosal, Zachary Rahe, Arthur Pamboukis
Laser Ablation Of Aluminum, Erika Nosal, Zachary Rahe, Arthur Pamboukis
Williams Honors College, Honors Research Projects
The laser ablation of metal carries relevance in a variety of engineering industries. This includes, but is not limited to, processes such as micromachining, or implementation on aircraft weaponry. The latter application is the reasoning for why aluminum is the specific metal in consideration, as it is commonly used for the construction of aircraft components.
The scope of this project was to optimize the energy dispersed through laser ablation on aluminum by mathematical modeling. The transient conduction process in the aluminum was modeled using a 2-dimensional cylindrical coordinate system in both MATLAB and ANSYS/Fluent. These models were adopted to simulate …
