DRAWING AND SHOP-WORK.

Systematic instruction in Engineering Drawing is given through the
Freshman and Sophomore years. The student is carefully trained in the
technique of good draftsmanship. Especial attention is paid to free-hand
lettering. The importance of neatness, accuracy, clearness and completeness

is constantly impressed upon the student's mind. Frequent exercises
in tracing and blue printing are required. As the student advances in the
course he is taught more and more to use the graphical method not merely
as a means of representation, but as an instrument of research both in
Geometry and in Mechanics. To the Junior and Senior students are
assigned by their respective professors such further drawings as are needed
for the full development of the courses of instruction.

Freshman Drawing: Lecture Courses.

11-12, T. Th. S.

600. Practical Geometry. [Thornton.]

This course presupposes good high-school training in plane and solid
geometry and in the rudiments of plane trigonometry. It embraces a
review and extension of the fundamental problems of plane geometry with
applications to the mensuration of rectilinear and curvilinear figures; an
elementary study of the conic sections and of the methods of constructing
these curves; the orthographic projection of polyhedra and of the three
round bodies in erect and oblique positions; sections of curved surfaces by
planes and intersections; the mensuration of solids and Simpson's rule;
the graphical solution of equations; and the theory and use of the Polar
Planimeter. (Fall.)

601. Machine Construction. [Hancock.]

A study of the hand and machine tools in the wood and machine shops
and of the testing machines in the laboratories, involving careful investigation
of their functions, construction, and operation; free-hand sketching
of machine parts; elementary problems in the computation of shafting,
belting, rope drives, toothed gears, etc. Illustrative and descriptive lectures
are given and a large number of questions and problems are assigned the
student to guide him in the study of each machine. (Winter.)

700. Plane Surveying. [Newcomb.]

Described under Civil Engineering. This course develops the theory
of the construction of the plans, profiles, and maps used in the course of
Topographical Drawing (652). (Spring.)

Freshman Drawing: Practice Courses. [Hancock and Assistant.]

Each student executes one finished plate 15″ by 20″ weekly. These
plates are drawn under the supervision of the assistant instructor and
must be neatly finished, lettered and dimensioned. Every student is required
to make tracings and blue prints of a certain number of his own
plates.

650. Mechanical Drawing.

11-2, M. W.

This course embraces careful training in technique, assiduous practice
in lettering, and the graphical solution in the weekly plates of a series of

carefully selected problems in practical plane and solid geometry, and in
graphical algebra and trigonometry. (Fall.)

651. Machine Drawing.

11-2, M. W.

Carefully constructed and finished plates consisting of detailed working
drawings of machine parts. The drawings are made, in part, from
free-hand sketches from the machine itself, and, in part from designs and
specifications worked out by the student in the class in Machine Construction,
601. (Winter.)

652. Topographical Drawing.

11-2, M. W.

In this course the conventional methods of making topographical maps
are carefully taught. Each student is required to become reasonably proficient
in the preparation of such maps. Particular attention is paid to
the study of contoured plans and the solution of problems based on them.
(Spring.)

Sophomore Drawing: Lecture Courses.

11-12, M. W. F.

603. Graphical Statics. [Thornton.]

The necessary preparation is such knowledge of experimental mechanics
as is given in Physics, 200. The theory and use of graphical
methods in mechanics are carefully taught and illustrated by means of
problems in the composition and resolution of forces and moments.
Applications follow to the determination by graphical methods of centers
of gravity and moments of inertia, to the construction of strain sheets
for the simpler forms of roof and bridge trusses, to the study of the stability
of dams and walls, and to the calculation of internal stress in
girders, and beam deflections. (Fall.)

605. Structural Design. [Thornton.]

The methods developed in the course on Graphical Statics are applied
to the analysis and design of simple beam bridges; of reinforced concrete
slabs and beams; of plate girders; of retaining walls for earth; and of
simple types of framed structures. Special attention is given to the
structures important in Highway Engineering. (Winter.)

604. Descriptive Geometry. [Thornton.]

The fundamental problems on the point, line, and plane are carefully
studied, with applications to the construction of shadows on polyhedra and
to the graphical statics of force-systems in three dimensions. The projections,
tangencies, sections, and intersections of curved surfaces are then
taken up, with applications to the determination of shades and shadows on
such surfaces. The course concludes with an elementary theory of linear
perspective. (Spring.)

Sophomore Drawing: Practice Courses.

12-2, T. Th. S.

653. Graphical Statics. [Thornton and Assistant.]

Fall.

655. Structural Drawing. [Thornton and Assistant.]

Winter.

654. Descriptive Geometry. [Thornton and Assistant.]

Spring.

The work of the course is the execution each week of a plate 15″ by
20″, the problems assigned being such as serve to illustrate the topics
discussed in the associated lecture-courses and develop power in the use
of graphical methods. Each student is required also to trace a certain
number of his plates, to make blue prints from his tracings, and to use
the planimeter for the mensuration of areas and volumes bounded by
curved lines and surfaces.

Shop Instruction is given for its educational value. The purpose of
this Department is to train engineers, not artisans; and the claims of
the shops are not permitted to infringe on the truly vital functions of the
laboratories, the drafting rooms, and the lectures.

Freshman Shop-work. [Hancock and Assistants.]

3 hours a week.

660. Wood Shop.

Bench exercises in sawing, planing, boring, chiseling, tool sharpening.

Lathe exercises in turning between centers and on a face plate.

Machine tool exercises in the production of useful articles.

661. Machine Shop.

Bench exercises in chipping and filing.

Engine lathe exercises in turning, boring, and thread cutting.

Machine tool exercises in drilling, planing, shaping, and milling.

These exercises, which are required of all students in engineering,
occupy three hours a week throughout the Fall and Winter Terms. During
the Spring Term the class is divided into small squads, each of which
devotes three afternoons a week to exercises in Field Surveying. (Civil
Engineering: Course 750.)

Junior Shop-work. [Hancock and Assistants.]

3-6, M. W.

662. Machine Shop.

Bench and machine-tool work in the construction of articles of commercial
value. An extension of 661. (Fall.)

663. Pattern Making; Foundry; Forge Shop.

Simple solid and split patterns and core boxes; core making, moulding,
and casting; exercises in forging iron and steel; forging and tempering
center punches, cold chisels, lathe and planer tools. (Spring.)

These courses are required of all students of Mechanical and Electrical
Engineering.

Senior Shop-work. [Hancock and Assistants.]

12 hours a week.

664. Machine Shop.

A continuation of the Junior Shop-work (662). More intricate and
complicated pieces are constructed and a broader understanding and improved
technique are developed. (Winter.)

This course is required of students of Mechanical Engineering only.
