Engineering

Professors Wiggins, Gallagher, Hennings, Royce and Werner

Engineering science courses deal with the application of knowledge gained in the basic sciences to the solution of engineering problems, using the theories and techniques of mathematical analysis. The principles learned are later applied in ship and power plant design. Engineering drafting and laboratory skills are included in this group of courses.

The extensive use of computers in the engineering and business communities makes it essential that all Webb graduates be literate in computer use and skilled in using complex programs. Some exposure to and practice in varied computer capabilities are stressed, including scientific and engineering problem solving, word processing and computer-aided graphics.

Freshman Year

           PROGRAMMING AND APPLICATIONS

This course provides an introduction to computer programming and focuses on the development of the logical problem-solving skills that are essential in engineering.  Topics covered include logical expressions, conditional statements, variable types, looping, subroutines, and functions.  The ability to properly annotate and debug coding will be stressed.  Student skills in the application of widely-used, commercially-available software such as Excel®, MathCad®, Visual Basic for Applications (VBA®), and Maple® are developed and exercised to facilitate their use in subsequent mathematics, science, and engineering courses.  Two hours of class and one hour of laboratory per week in the first semester.        

          STATICS

This is a course in applied vector mechanics with emphasis on static equilibrium.  Topics include forces, moments, couples, equivalent force-couple systems, controls, distributed forces, and Coulomb friction.  The application of the free body diagram in the analysis of static equilibrium of frames, machines, and trusses is stressed.  Three hours of class per week in the second semester.

Sophomore Year

          STRENGTH OF MATERIALS

Stress-strain relationships of engineering materials are treated. Rods, shafts, beams and columns subjected to tension, compression, torsion and shear loadings are examined. Introduction of the finite element method is presented and some simple problems are solved. Mohr's Circle analysis of stress and strain is developed. Thermal effects, column buckling and limit design concepts are also treated. Three hours per week in the first semester.

          ENGINEERING GRAPHICS (CAD)

This course develops the student's power of visualization.  Students are introduced to fundamentals of computer-aided-drafting (CAD), and use a PC-based CAD program (AutoCad) to produce orthographic and isometric views of 3-D objects. A final project drawing is a typical midship section using CAD, incorporates skills developed in class. Two hours of computer lab per week in the first semester.

          THERMODYNAMICS

Properties of fluids, concepts of the system, control volume, work, heat, energy, entropy, the laws of thermodynamics, and reversibility are studied and applied to topics in power cycles, combustion, and psychrometry. Three hours per week in the first semester.        

          DYNAMICS

The motion of particles and rigid bodies is studied. Topics include: kinematics and kinetics of particles, kinetics of systems of particles, plane kinematics and kinetics of rigid bodies, and three dimensional dynamics of rigid bodies.  Three hours per week in the second semester.

          FLUID MECHANICS

This course examines both real and ideal fluids. The Bernoulli Equation is developed and applied to fluid measurement. Finite control volume and differential analysis is developed and applied to fluids in motion.  The velocity potential and stream functions are introduced and applied to simple planar flows. Other topics include fluid statics, kinematics, dimensional analysis and modeling, and viscous flow in pipes. Three hours per week in the second semester.

Junior Year

          VIBRATIONS

This course examines single and multi-degree of freedom models.  Free and forced system response is developed for simplified systems and extended to topics relating to ships. Complex algebra and Fourier series are used throughout.  Vibration measurement is discussed and demonstrated.  Exact and approximate methods for determining mode shapes, natural frequencies, and modal analysis are included.  Analysis of continuous systems is introduced. Three hours per week in the first semester.

          HYDRODYNAMICS

This course introduces ideal and viscous flows related to ships. Boundary layer theory is developed in relation to lifting surfaces and hull forms.  Lift and drag topics include NACA foil sections, lifting line theory, Joukowski airfoils, and Glauert's method for optimum planform.  Green's functions are introduced for simplified potential theory problems.  Potential theory is further developed for added mass and damping on a circular cylinder.  Prediction of impact force is presented in terms of von Karman's impact theory.  Forces on a column are examined using Morrison's equation.  Computational Fluid Dynamics is introduced for simplified problems. Three hours per week in the second semester.
