Background RIT changing from quarters to semesters in Fall 2013 First year students currently take Physics, Problem Solving with Computers and Measurement Instrumentation and Controls ME 102 will replace these courses Lab hardware needs to be developed for five labs  Three labs to be integrated into ME 102  Two in class demonstrations  Statics  Thermodynamics

Benchmarking Empathy Exercise Examined current lab facilities in the RIT ME Department Researched existing lab experiments used by other universities  Did not find any labs that addressed the needs of ME 102  Did not find any universities that had a course comparable to ME 102 Researched existing lab kits and demonstrations  Pasco  ENGAGE

Mission Statement The Mechanical Engineering Department at the Rochester Institute of Technology will be implementing a new course curriculum by Fall 2013, including lab experiments for first year students, because it will be a more effective way to introduce key engineering principles early in their education. The ME Lab Hardware family of projects will be responsible for the design, development and production of this lab hardware.

The customer needs experiments that are robust and easy to assemble so that a significant number of students can have a hands-on experience with one piece of hardware in under 75 minutes. The customer needs experiments to address Newton’s Law of Gravity because it is a foundation principle of mechanics. The customer needs experiments to address Newton’s Three Laws because they are a foundation principle of mechanics. The customer requires that the student must demonstrate knowledge of and ability to apply the Work Energy Theorem. The customer requires that the student demonstrate an ability to conduct scientific experiments, using appropriate technology to collect sensor data in order to achieve the desired outcomes. The customer needs students to have data acquisition, data processing and technical writing because they are critical engineering skill sets. The customer needs the experiments to be ready by May 2012 because the experiments are going to be implemented by the Fall of The customer needs experiments that increase in complexity because this will help ease students into more complex concepts. The customer needs the experiments to utilize National Instruments DAQ hardware and commercial off-the-shelf parts to meet lab production time and resource constraints. The customer needs a series of experiments that demonstrate key engineering concepts. The customer needs experiments that can be effectively implemented by May 2012 to establish RIT as a national education standard. The customer needs experiments that help students obtain and analyze data from lab hardware while developing other important technical skills. The Mechanical Engineering Department at the Rochester Institute of Technology will be implementing a new course curriculum by Fall 2013, including lab experiments for first year students, because it will be a more effective way to introduce key engineering principles early in their education.
