Admittance to Degree Program
Students are expected to meet minimum college entrance requirements. After being admitted to the college as pre-mechanical engineering students, students wishing to pursue a degree in mechanical engineering must further be admitted to the degree program. Students who have completed 43 credit hours applicable to their mechanical engineering degree are considered for formal admission to the mechanical engineering degree program. Typically, this occurs the semester the student is enrolled in MECH 200 or MATL 360. Those exceeding 61 credit hours must receive formal admission to the mechanical engineering degree program if they are to continue to take mechanical engineering courses. Transfer students must have at least 12 credit hours of course work from the University of Nebraska–Lincoln on record before an application will be considered. Applications are judged on a competitive academic performance basis; consult the Department of Mechanical and Materials Engineering website for specific details.
One major focus of the Department is to provide students with many hands-on opportunities both within the curriculum (through formal laboratory courses) and through extracurricular activities. Brief descriptions of some of the laboratories in the department are given below.
The Materials Laboratory is designed to study the development of microstructures during processing, and to correlate the properties of materials with the observed structures. Undergraduates utilize arc melting facilities for solidification processing and alloy formation, rolling mills for deformation processing, and a variety of furnaces for thermal treatments. Characterization facilities include x-ray diffractometry and optical microscopy, while property measurements are completed using hardness testing (including microhardness), tensile testing, and impact testing facilities. Other facilities associated with the materials laboratory include rapid solidification processing facilities and electron microscopy facilities.
The Measurements Laboratory is associated with the required MECH 380 Mechanical Engineering Measurements course which includes two hours of lecture and two hours of laboratory work each week. The course covers the fundamentals of mechanical engineering measurements including data analysis (statistics, graphing, spectral analysis), signal conditioning, data readout, and the measurement of length/displacement, rate of rotation, stress/strain, temperature, pressure, fluid velocity, fluid flow rate, vibration/acceleration, and sound. The MECH 380 Lab has four workbenches. Each workbench has set of basic measurement equipment including a digital oscilloscope, an electronic counter, a digital multimeter, a DC power supply, a function generator, and a computer-based data acquisition system consisting of a personal computer with data acquisition software and interfaced analog-to-digital converter and digital counter cards. In addition, on a week-to-week basis, specialized equipment is brought out of the cabinets and set up for each of the nine (some one week, some two week) labs.
The Kinematics and Machine Design Laboratory is a teaching laboratory for undergraduate students. The laboratory consists of equipment and instruments for conducting experiments in kinematics and machine design. One piece of major equipment is the rapid prototyping machine, which accepts design specifications from a computer and forms a prototype of the design using plastic injection. This machine provides the student with experience in design integration from concept to product. We have also recently upgraded the rapid prototyping laboratory with the acquisition of the MakerBot Thing-O-Matic 3-D printer kit. This 3D printer uses ABS plastic to create rapid prototyped objects with better than 1 mm feature resolution; it accepts standard CAD models converted to g-code and is a low-cost alternative to high-end rapid prototyping services or equipment. Accessories in this laboratory include desktop computers, a wide-carriage printer, and other instruments. Kawasaki also donated a retired robot that is now utilized in this laboratory.
The Thermal Fluids Laboratory involves design, execution and evaluation of physical experiments in the areas of thermodynamics, fluid mechanics, and heat transfer. There are three major, heavily-instrumented experiments: 1) a two stage air-compressor with intercooling, 2) a versatile air conditioning unit, and 3) a Ford gasoline engine with a Superflow water brake dynamometer, supported with a data acquisition system. The course involves design, execution and evaluation of physical experiments in the areas of thermodynamics, fluid mechanics, and heat transfer. In addition, the facilities include “table top” instrumentation for viscosity measurement, measurement of pressure distribution on an airfoil, flow visualization and head loss across a valve on which students conduct experiments.
The Mechatronics Laboratory is well-equipped for teaching courses in mechatronics and robotics. It is used primarily for MECH 457, but is also used for other courses, and by both undergraduate and graduate students working on research projects. The laboratory contains desktop computers, modular robots, digital oscilloscopes, function generators, computer controllers, soldering systems, and many other accessories.
The Department also has computational facilities available to students. The computer lab has a suite of personal computers with a full complement of computing resources available to students.
Research Laboratories. These laboratories, extensions of those described above, are equipped for research in the fields of fluid mechanics, heat transfer, thermodynamics, turbulence, flow visualization, fluid mechanics, measurements, turbomachinery and engine research, combustion, materials, mechanical design, dynamics, computational, solid and applied mechanics, biomedical engineering, and controls. Many of our undergraduate students gain valuable experience working on research projects under the guidance of professors. These are funded by research grants or the University’s UCARE program.
Some of the extracurricular opportunities for students to gain hands-on engineering experience include SAE Baja, SAE Formula (both through Husker Motorsports), NASA microgravity, AIAA competitions, and others.
College Entrance Requirements
Students must have high school credit for (one unit is equal to one high school year):
1. 4 units of mathematics: 2 of algebra, 1 of geometry, 1 of precalculus and trigonometry.
2. 4 units of English.
3. 3 units of natural science that must include 1 unit of physics and 1 unit of chemistry (chemistry requirement waived for students in construction management).
4. 2 units of a single foreign language.
5. 3 units of social studies.
6. Students having a composite ACT score of 28 or greater (or equivalent SAT score) will be admitted to the College of Engineering even if they lack any one of the following: trigonometry, chemistry, or physics.
A total of 16 units is required for admission.
Students must have an ACT (enhanced) score of 24 or greater (or equivalent SAT). Students who lack entrance requirements may be admitted based on ACT scores, high school rank and credits, or may be admitted to pre-engineering status in the Exploratory and Pre-Professional Advising Center. Pre-engineering students are advised within the College of Engineering.
Students who lack entrance units may complete precollege training by Independent Study through the UNL Office of On-line and Distance Education, in summer courses, or as a part of their first or second semester course loads while in the Exploratory and Pre-Professional Advising Center or other Colleges at UNL.
Students should consult their adviser, their department chair, or the Office of the Dean if they have questions on current policies.
Other Admission Requirements
Students who transfer to the University of Nebraska–Lincoln from other accredited colleges or universities and wish to be admitted to the College of Engineering (COE) must meet COE freshman entrance requirements and have a minimum cumulative GPA of 2.5. Students not meeting either of these requirements must enroll in the Explore Center or another UNL college until they meet COE admission requirements.
The COE accepts courses for transfer for which a C or better grade was received. Although UNL accepts D grades from the University of Nebraska at Kearney and at Omaha, not all majors in the COE accept such low grades. Students must conform to the requirements of their intended major and, in any case, are strongly encouraged to repeat courses with a grade of C- or less.
All transfer students must adopt the curricular requirements of the undergraduate bulletin current at the time of transfer to the COE—not that in use when they entered UNL. Upon admission to UNL, students wishing to pursue degree programs in the COE will be classified and subject to the policies defined in the subsequent section.
College Degree Requirements
In the event of a dispute involving any college policies or grades, the student should appeal to his/her instructor, adviser, and department chair (in that order). If a satisfactory solution is not achieved, the student may appeal his/her case through the College Academic Appeals Committee on his/her campus.
Students must fulfill the requirements stated in the bulletin for the academic year in which they are first admitted at UNL. In consultation with advisers, a student may choose to follow a subsequent bulletin for any academic year in which they are admitted to and enrolled as a degree-seeking student at UNL in the College of Engineering. Students must complete all degree requirements from a single bulletin year. The bulletin which a student follows for degree requirements may not be more than 10 years old at the time of graduation.
