Asme R/C Baja Car, Torrie Large Jan 2018

Asme R/C Baja Car, Torrie Large

Engineering Technology, Safety and Construction Senior Projects

How does one build a car? Do they start with the tires and build inward or do they develop separate aspects at the same time? This remote-controlled car was designed and built with the intention of competing in the annual Baja Competition. There are three competitions: sprinting, slalom, and an obstacle course. The suspension system of this car must be designed to support the car for both the physical build and the competitiveness. It must do this without interfering with the drive train and steering mechanism designed by Doug Erickson. The suspension system employs suspension arms attached to the chassis ...

H.F. Hauff Pruner Cutting Blades, Wyley Stewart

Engineering Technology, Safety and Construction Senior Projects

Apple orchards are a critical component of agriculture in the United States, and keeping the apple trees in the best shape for optimum growth and production is hard work. Neil Hauff, an agriculture industry expert, challenged students at CWU to engineer a power assisted tree pruner. Across the country, apple orchards need pruned every season. The pruning of the trees is strenuous manual labor that requires many man hours. The proposed solution is to create a power assisted tree pruner that would minimize the amount of work needed to trim each tree branch. This project has been separated into three ...

Title by Author: Shear Energy by Jason Wittig

Abstract/Artists Statement: Efficiency, function, and weight of fruit-tree pruning devices are scrutinized very closely by the purchasing end user. Efficiency, being the most valuable quality to focus on; an efficient cutting device can lead to smaller batteries and lighter materials on the tree pruner. The objective of this project was to produce a cutting head that surpassed the benchmark device by 10% in four categories: Axial cutting “green-wood,” Axial cutting “dry-wood,” Axial opening force, and Handle twisting torque. The benchmark’s use of the “scissor-type” design was changed to a double ...


Senior Project Hauff Tree Pruner, Brian Woolery Jan 2018

Senior Project Hauff Tree Pruner, Brian Woolery

Engineering Technology, Safety and Construction Senior Projects

Neil Hauff, a business owner and entrepreneur from the Yakima valley challenged a team of engineering students from Central Washington University to design a motorized apple tree pruner. This report will discuss the engineering and construction that went into creating the housing of the tree pruner. The housing component needed to be able to protect the moving parts of the pruner, while withstanding the rotational torque produced by the Makita power drill used to drive the pruner. The biggest constraint in designing the housing was to keep the weight of the housing component under 1.5 lbs, while still keeping ...


Asme Rc Baja Challenge: Suspension And Steering, Hunter W. Jacobson Jan 2018

Asme Rc Baja Challenge: Suspension And Steering, Hunter W. Jacobson

Engineering Technology, Safety and Construction Senior Projects

The American Society of Mechanical Engineers (ASME) usually hosts an RC Baja challenge each year, testing a RC car in three events: slalom, acceleration and Baja. Although ASME will not be holding an event this year, CWU will be holding a similar event with three RC Baja car teams from CWU. The RC car that is tested in these events is designed and manufactured typically in teams of two. The RC car that each team submits must be able to complete these events while also remaining competitive. One part of great importance for the RC car is the suspension and ...


A Comparison Of Traditional Education And Project-Based Education In Construction Management, Trey Miller Jan 2018

A Comparison Of Traditional Education And Project-Based Education In Construction Management, Trey Miller

University Honors Program Theses

Construction is a rapidly moving and constantly changing industry. The skills needed to manage the complex task of running a job site safely, on schedule, and within budget, are unique to the field. Construction Management as an academic field is relatively new discipline. Therefore the field is still rapidly evolving. In many cases, classes are taught by engineering professors, which leads to an engineering-focused education as opposed to a Project Management focused education. Therefore Construction Management students are not receiving the “hands-on” experience early enough in their studies. By structuring classes around an applied project, students will attain a more ...
