The purpose of this exam is to evaluate a student's ability to design engineering systems efficiently and effectively. The exam will cover the conception, planning, evaluation and implementation of engineering system designs. Emphasis is placed on engineering systems which are interdisciplinary and typically require the consideration and integration of several of the traditional engineering disciplines. Therefore, to a large extent, success in this examination will depend upon a student's ability to apply design methods and integrate basic knowledge of the engineering sciences. Specific areas which are emphasized in the examination are as follows: 1. 2. 3.
The examination will assume knowledge of material normally covered in the undergraduate core curriculum in mechanical engineering at Georgia Tech, but will presume the maturity and experience commensurate with a graduate student at the master's level. The primary courses to which this examination will relate are: ME 3180 (Machine Design)

The purpose of this examination is to evaluate the student's understanding of the principles governing the dynamics of rigid and elastic systems and to synthesize those principles to predict the response of mechanical systems. A key aspect of the required expertise is demonstrated by the ability to anticipate and explain response characteristics based on physical arguments. Topics will be drawn from the following: 1. Kinematics of particles and rigid bodies: Analysis of velocity and acceleration for curvilinear motion, motion relative to a moving reference frame, angular motion, linkages, rolling bodies. 2. Kinetics of particles and rigid bodies: Free-body diagrams, inertia properties, equations of motion for planar and spatial motion, static and dynamic balancing, gyroscopic effect, linear and angular impulse-momentum principles, work-energy principle. 3. Vibration of one-degree-of-freedom systems: Free response with damping, response to harmonic, periodic and transient vibration, vibration measurement and control. 4. Vibration of systems having several degrees of freedom: Evaluation of natural frequencies and modes, modal response to excitation, harmonic forced response, vibration absorbers, Raleigh ratio. 5. Vibration of simple continuous systems: Natural frequencies and modeshapes for simple structures such as strings, rods, and flexural beams. Estimation of natural frequencies using approximate techniques such as assumed modes, or Rayleigh-Ritz.

-Numerical Methods: Formulation and solution of engineering analysis problems using various numerical methods, including methods for numerical differentiation and integration, solving of ordinary differential equations, linear regression, root finding, optimization, eigenvalue, and boundary value problems. The student should understand sources of error and their implications for practical implementations of typical numerical methods. After finding the solution to an analysis problem, the students should be able to interpret the results: What does this imply for an engineering problem? How sensitive is the solution to changes in loading and boundary conditions? Or to changes in parameter values? -Finite Element Analysis: Formulation and solution of finite element models. Given a "real-world" analysis problem, you may have to select appropriate element types and identify appropriate boundary and loading conditions. Insight into identifying the governing physical phenomena for engineering systems will also be important. The student should understand the governing principles and assumptions underlying the finite element technique. -Geometric Modeling: Curve and surface modeling techniques. Given an engineering design problem, which curve/surface modeling technique would be appropriate, based on an understanding of fundamental technique properties and analysis of problem requirements? Why are components shaped the way they are and how would their shape be described (using CAD systems)? Other topics include the limitations of curve and surface models and the application of geometric modeling to shape design and component analysis, with analysis related to the formulation of finite element and other types of models.
