RC Baja
To satisfy the Mechanical Engineering Technology program requirements a senior project was accomplished with an RC car build. An RC car was designed, manufactured, and tested to meet all requirements set forth by American Society of Mechanical Engineers (ASME) RC Baja competition. A two-person team was assembled to build the RC Car. Teammate Paul Lervick was responsible for the suspension and chassis components and the other was responsible for the drivetrain and steering components. During the fall quarter drawings and general designs were created. Many different RC cars and motorized vehicles were referenced when initially coming up with aesthetic ideas. After having a general idea on appearance, engineering analyses were calculated. Several torque analyses were made on gears to assure they would hold up under the power of the 3800Kv motor. Steering component geometry was analyzed after finding the desired steering arm length of 93.75mm. After several analyses were made, decision matrices were created to decide which materials were most appropriate to manufacture components out. After design and analysis came manufacturing and construction. Most components were 3D printed and purchased. Multiple machining processes were utilized to modify parts for fitment and aesthetics. With a fully constructed RC car, testing began. The RC car met the steering requirement of articulating left and right at the desired 60 degrees, and also reached 25 mph top speed as calculated. Additional tests include a slalom course and a drop test
Wilderness & the Geotag: Exploring the Relationship between Georeferenced Social Media Data and Recreational Visitation in the Alpine Lakes Wilderness, WA
Many have raised concerns about the impact of geotagged social media images on public lands. They claim that geotags increase recreational visitation which subsequently contributes to negative recreational impacts including crowding, trampled vegetation, erosion, and litter. Others, however, claim that geotagging on social media has made the outdoors more accessible to less privileged communities and raise concerns that restricting geotags will perpetuate the exclusion of certain groups from nature. This debate is particularly relevant to federally designated wilderness. Wilderness is legally defined as untrammeled by man, and this problematic construction has helped justify indigenous land dispossession and restricted access for other marginalized populations in wilderness areas. This paper will present the results of research that explores the relationship between geotags, visitation, and the perception of recreational impacts within the Alpine Lakes Wilderness in Washington. It uses a GIS kernel density analysis to determine which locations are most frequently geotagged on Flickr and Instagram and then surveys visitors at these sites to ascertain if geotags played a role in individuals\u27 decisions to visit. It also explores whether recreational impacts negatively affect visitor experience at these sites and explores visitors’ expectations for wilderness. The findings of this study suggest that social media does play a role in some visitors travel decisions, however few visitors consider geotags specifically when making their decisions. Furthermore, this research suggests that, despite individuals\u27 concerns that geotags are ruining nature, the majority of visitors\u27 expectations are still being met within frequently geotagged sites in the Alpine Lakes Wilderness.
