Team Chain Reaction is tasked with making improvements upon the current Pennsylvania State University (PSU) Human Powered Vehicle (HPV). Fixing the major components, implementing an aerodynamic windshield and adding aesthetics are the main challenges the team is faced with. After initially meeting with the team’s sponsor, Dr. Anne Martin, the team discovered that the major components to be fixed are the braking system and seat adjustability. The main deliverable of the project is a working and improved HPV that will succeed in the American Society of Mechanical Engineers Engineering Festival (ASME E-Fest) North Human Powered Vehicle Challenge (HPVC). The HPVC will take place at Michigan State on April 3 - April 5. The team has a limited budget of $1000 that will be spent primarily on materials since registration and travel fees are mostly covered. The team anticipates needing to spend about 80% of the total budget to successfully complete the project. Most of the budget will be spent on creating the aerodynamic windshield. The rest of the budget will be allocated towards the other major components, safety requirements, aesthetics, and a poster. In order to complete the required tasks on time, a Gantt chart was created and is constantly being updated. Using a Gannt chart allows the team to layout major milestones and tasks that need to be completed within the restricted time frame. The Gannt chart assists the team in differentiating tasks for the HPVC and the Penn State Mechanical Engineering (ME) 440 Capstone course. The overall deliverable deadlines for the HPVC and ME 440 Capstone are April 3 and May 5, respectively. The Gannt chart ensures the students are on track and will succeed in both the HPVC and ME 440 Capstone. 2 Table of Contents Commented [NG4]: Uses Microsoft Word automated Table of Contents…good!

These vehicles fall under a variety of categories: land, introductory paragraph instead of awkwardly jumping right into the next sub-section. water, rail and air.

Kayaks and canoes are examples of water HPVs used for leisurely activities. Human-powered submarines have given engineers a true challenge due to the constraints of pedaling underwater (Bennett). A draisine is a rail HPV that is used to carry workers to maintain the railroad tracks (Elder). The Icarus Cup is a competition in the United Kingdom for various forms of human-powered aircraft (British Human Powered Flying Club). The American Society of Mechanical Engineers (ASME) Engineering Festival allows for engineering students to put developing technical skills to the test through an assortment of competitions. In addition to the engineering competitions, the ASME Engineering Festival provides additional opportunities for students to network. The first networking opportunity is “Lightning Talks” where professional engineers in industry discuss new technologies in the field (ASME E-Fests). The second networking opportunity is career mentoring where practicing engineers describe the working environment in industry upon graduating. The final networking opportunity includes a resume and professional development workshop. With all these professional experiences, the ASME Engineering Festival also provides social activities and performances for engineering students to meet other engineering students. The team is registered for the Human Powered Vehicle Challenge (HPVC) that takes place at Michigan State University from April 3 to April 5. This competition tasks the team with utilizing engineering skills to create a human-powered form of transportation (ASME E-Fests). This year’s competition requires the teams to create a recumbent tricycle. Recumbent tricycles are similar to bicycles, but recumbent tricycles contain three wheels and the rider lays back while riding Commented [NG7]: Microsoft Word has underlined this (Recumbent Gourmet). Considering the competition has speed events, the HPV must be capable to indicate there is a potential issue here. of traveling at high velocities for maximum success. Overall, the HPVC expects teams of I stopped editing for commas at this point. There are many online comma usage sources out there including engineering students to develop an efficient and feasible form of transportation. http://writingcenter.unc.edu/handouts/commas/ The HPVC is scored upon two different stages: design report and performance. Due by February 18, the design report is graded using specific scoring criteria. There are three major components of the design report: design, analysis and testing. In addition, the vehicle will be analyzed on safety and aesthetics. The performance of the vehicle is assessed by a drag race and an endurance race (ASME E-Fests). For both race categories, a male and a female from the team must compete. Trophies are given to the top three teams for each event with the first-place team each receiving a cash prize. The top three overall teams both receive a trophy and a cash prize. Knowing this, the team has an additional incentive to work hard on the Capstone Project and succeed at the HPVC. 4 1.1 Initial Problem Statement Dr. Anne Martin, a mechanical engineering professor at Penn State, explained during the initial sponsor meeting the main problem of the Capstone Project is the major components of the previous HPV must be improved. Primarily, an aerodynamic windshield must be implemented to protect the rider and increase the overall efficiency. Secondly, the braking system is faulty and must be fixed before the competition.
