University of Virginia Library

FOURTH YEAR COURSE.

To the studies of this year only those men are admitted who
have completed the required work in Pure Mathematics and have a
good knowledge of Mechanics. Courses 2 and 3 in Applied Mathematics
are essential for success in the technical engineering courses.

Applied Mathematics 4. [Thornton, 9.]

This course constitutes a complete survey of Analytical Mechanics.
The Fall Term is given to Analytical Statics, the Winter Term to

the Dynamics of a Particle, the Spring Term to the Dynamics of a
Rigid Body. For illustrative material use is made not only of such
classical topics as harmonic motion, projectile motion, planetary
motion, meteoric motion, motion in resisting media and so on; but
examples are taken also from engineering practice in the Kinematics
of Machines, the Dynamics of the Steam Engine, the Balancing of
Single and Coupled Engines, and others of the great problems of
scientific engineering.

Chemistry 2. [Mallet, 3.]

This course in Industrial Chemistry is concerned with the application
of chemistry to the arts and manufactures. Among the topics
discussed are the metallurgy of iron, steel, copper, tin, aluminum, and
the precious metals; the manufacture of limes and cements, bricks,
artificial stones, and other building materials; the chemistry of explosives,
lubricants, paints, and other preservatives. The lectures are
copiously illustrated by charts and drawings and by specimens furnished
from an extensive and costly Museum of Industrial Chemistry.

Economic Geology 2. [Watson, 1.] Required for E. M.

This course deals specifically with Economic Geology, the course
in Economic Geology 1 or an equivalent being prerequisite. It is designed
to give a general but comprehensive account of the origin,
distribution and uses of the metallic and non-metallic products of the
earth, with especial reference to those of the United States. Three
lectures are given each week and nine additional hours are allowed for
laboratory work, field surveys, collateral reading, and private study.

Civil Engineering 2. [Newcomb, XI.] Required for C. E.

Masonry Construction is studied in the Fall Term. The materials
used, the methods of inspection and testing, the standard specifications
for the work, and the analysis and design of walls, piers and
arches are minutely discussed. The methods for the construction of
foundations are thoroughly studied; and the design and execution of
works in reenforced concrete receive adequate attention. In the
Winter Term the topics are Water-works and Sewers. The collection,
purification, conveyance, and distribution of city water supplies are
discussed. The problems of city sewerage and sewage disposal are
also carefully investigated. The Spring Term is given to a study of
Long Span Bridges. The more intricate designs of simple trusses
are examined and the cantilever bridge, the steel arch, the continuous
girder, and the swing bridge are analyzed. Each student is required
to work out the stress sheets and the general drawings for some
specified type of long span bridge.

Mechanical Engineering 2. [McKergow, I.] Required for M. E.

The Fall Term begins with a review of the principles of hydraulics
and applies them to a thorough study of the design and construction
of such Hydraulic Machines as presses, pumps, motors, and hydraulic
power transmissions. The subject of the Winter Term is Mechanical
Power Plants; the location of such plants, the choice of units, and the
lay-out are discussed, and one or more typical plants designed. The
Spring Term is given to Locomotive Engineering, and studies the
operation, performance, construction, and design of steam locomotives;
special attention being given to the balance of the machine
and to the valve gears.

Electrical Engineering 2. [Holladay, XI.] Required for E. E.

The Fall Term is given to a more advanced study of Alternating
Current Phenomena as they present themselves in Transformers,
Induction Motors, Alternators, Synchronous Motors, and Rotary Converters.
In the Winter Term the phenomena of Electric Transmissions
for Light and for Power at both high and low voltages are
studied, together with electric incandescent and are lamps and their
photometry. The Spring Term is devoted to Electric Traction including
the study of motor capacity and design, train performance,
controllers, brakes, power houses, sub-stations, transmission, rolling
stock, roads, and the economics of the electric railway. The laboratory
exercises run parallel with the lectures through the entire course.

Mining Engineering. [Thornton, I.] Required for E. M.

The topics studied are in the Fall Term the Exploitation of Mines;
included are the principles to be observed in prospecting; the opening
of the mine; the extraction of the mineral; timbering and lighting;
mine explosions and other accidents; mine surveys and maps
and plans: in the Winter Term Mining Machinery; including the central
power plant and power transmission; the machinery for haulage
hoisting, drainage, and ventilation; and for hydraulic mining, quarrying
and ore dressing: in the Spring Term the uses of Electricity in
Mining for power, light, and signaling.

Thesis Work.

Every candidate for a degree in Engineering will be required at
the beginning of his graduating year to submit to the Dean some
subject for independent study suited to the student's especial course
and aims. After such subject has been approved by the Dean and
the Professor in charge, the student will be expected to carry out

for himself the necessary literary and laboratory researches and to
present his results in the form of a thesis. Such thesis must be
typewritten on standard sheets, 8 by 10½ inches, bound in a proper
cover, and handed in for final approval not later than May 25th.
All necessary computations and drawings must accompany the thesis.
Serious weight will be given to this work in estimating the student's
fitness for graduation.
