DRAWING AND SHOP WORK.
The first courses here listed are designed to furnish to the beginner
in engineering studies training in those preliminary disciplines,
which form a necessary part of his equipment, whatever the
speciality which he may later elect.
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 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.
In the Freshman year the work is distributed over the three terms
as indicated below, one finished plate 15″ by 20″ being required
of the student each week. The theoretical instruction is comprised
in courses 600, 601 and 700. The practical teaching is given at the
drawing board. The Sophomore course in Drawing requires each
week three hours of lecture work and nine of study and practice, of
which six are in the drawing-room under the tuition of the instructor
Courses in engineering practice are given throughout the year as
indicated below.
600 Practical Geometry. [Thornton.]
Lectures 11-12, Tuesday, Thursday, Saturday.
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; the mensuration of solids and Simpson's rule; the graphical
solution of equations, both algebraic and transcendental; and the
theory and use of the Polar Planimeter.
[Required, Fall, in Courses I, II, III, IV, V (1).]
601 Machine Construction. [Hancock.]
Lectures 11-12, Tuesday, Thursday, Saturday.
A study of the hand and machine tools in the wood and machine
shops and of the testing machines in the laboratory, 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.
[Required, Winter, in Courses I, II, III, IV, V (1).]
603 Graphical Statics. [Thornton.]
Lectures 11-12, Monday, Wednesday, Friday.
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 velocities
and accelerations, and of forces and moments. Applications follow
to the determination by graphical methods of centers of gravity and
moments of inertia, to the construction of stress sheets for the
simpler forms of roof trusses and bridges, to the study of the stability
of reservoir dams and retaining walls, and to the calculation
of internal stress in girders and shafts.
[Required, Fall, in Courses I, II, III, IV, V (2).]
604 Descriptive Geometry. [Thornton.]
Lectures 11-12 Monday, Wednesday, Friday.
The required preparation is given by the Freshman Drawing courses.
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.
[Required, Winter, in Courses I, II, III, IV, V (2).]
605 Structural Drawing. [Thornton.]
Lectures 11-12, Monday, Wednesday, Friday.
The methods of Graphical Statics and Descriptive Geometry are
applied to the design and analysis of a series of simple structures
in masonry, timber, steel, concrete, and so on. Incidental instruction
is given in the elements of stereotomy, the construction of
joints in carpentry, and the analysis of simple types of roofs and
bridges.
[Required, Spring, in Courses I, II, III, IV, V (2).]
650 Mechanical Drawing. [Hancock and Assistant.]
Hours 11-2, Monday, Wednesday.
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.
[Required, Fall, in Courses I, II, III, IV, V (1).]
651 Machine Drawing. [Hancock and Assistant.]
Hours 11-2, Monday, Wednesday.
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.
[Required, Winter, in Courses I, II, III, IV, V (1).]
652 Topographical Drawing. [Hancock and Assistant.]
Hours 11-2, Monday, Wednesday.
This course consists of six hours a week in the drawing-room
throughout the Spring Term of the Freshman year, and is devoted
to a study of the conventional methods employed in making topographical
maps. Each student is required to make a number of
plates, and to become reasonably proficient in the preparation of
such maps. Particular attention is given to the study of contour
maps, and the solution of problems relating thereto.
