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 2013.
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.
