Professors Wiggins and Williams

Under this heading are grouped the courses in physics, chemistry, and materials science.  These courses introduce scientific methods and provide training in the fundamentals upon which engineering knowledge depends. The courses in chemistry and materials science prepare the naval architect and marine engineer to cope with the materials used in shipbuilding.

Freshman Year


This is an introductory course in general chemistry. Topics covered include stoichiometry, inorganic reactions, ideal gases, condensed phases, chemical equilibrium, and acids and bases. Solubility, thermochemistry, and electrochemistry are also covered. Three hours of class per week and two hours of laboratory every other week in the first semester.


The course provides a rigorous introduction to elementary mechanics.  Vector algebra is introduced and used where appropriate. Newton’s Laws of Motion are introduced and applied to the kinematics and dynamics of particles and rigid bodies both for linear and rotational motion.  The subjects of forces on bodies, momentum, work and energy are described and applied to problems.   Three hours of class per week in the first semester. 


An introduction to wave theory starting with simple harmonic motion, mechanical waves, sound waves, light waves, traveling and standing waves.  Doppler effect, geometric and physical optics including reflection, refraction, diffraction and interference are also covered.  Two hours of class per week in the second semester.  Supporting laboratory exercises are conducted in the Science Lab course.


The structure-property-processing relationships of engineering materials are investigated.  Emphasis is placed on understanding the general behavior and capabilities of the different types of materials.  The primary focus of this course is on metals, especially steel.  Major topics include crystal structures, including crystal imperfections; diffusion in solids; mechanical properties, including tensile, hardness, impact, and fatigue testing; work hardening and annealing; phase equilibrium; and heat treatment, including non-equilibrium transformations such as martensite.  Other topics include introductory coverage of stainless steel, cast iron, polymers, and composite materials.  Optimal use of materials in ocean-going systems is stressed.  Three hours of class per week in the second semester.  Supporting laboratory exercises are conducted in the Science Lab Course.

          SCIENCE LAB

This course supports Physics II and Materials Science by providing hands-on laboratory exercises for both courses.  While half the class is performing a series of physics experiments dealing with basic wave mechanics, the other half is performing laboratory exercises to address material properties—from crystal structure modeling to microstructure imaging.  Mechanical properties of materials are also studied.  Two hours per week during the second semester.

Sophomore Year


This course covers electrostatic and electromagnetic fields; resistors, insulators and capacitors; magnetic properties of matter and inductance; instruments and measurements; circuit analysis using mesh currents and node voltages; transients and network theorems. Two hours of class and two hours of laboratory per week in the second semester.
