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

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 to address Newton’s Law of Gravity because it is a
foundation principle of mechanics.
The customer
needs a series of
experiments that
demonstrate key
engineering
concepts.
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
experiments that can

implemented by May
2012 to establish RIT
as a national
education standard.
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 that
help students obtain
and analyze data
from lab hardware
while developing
other important
technical skills.
The customer needs experiments that increase in complexity because this will help
ease students into more complex concepts.

The customer needs open source, ABET approved experiments that can be
implemented by other universities because RIT would like to become a national
standard in education.
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 utilize National Instruments DAQ
hardware and commercial off-the-shelf parts to meet lab production time and
resource constraints.
