Drawing 2. [Thornton and Gallalee].

This course 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. The distribution of topics is as below: Hours,
12-2, Tuesday, Thursday, Saturday. Lectures, 11-12, Monday, Wednesday,
Friday.

Fall Term.—Graphical Statics.—The necessary preparation is such
knowledge of experimental mechanics as is given in Physics 1. 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.

Winter Term.—Descriptive Geometry.—The required preparation is
given by Drawing 1. The fundamental problems on the point, line, and
plane are carefully studied, with applications to the construction of
shadows on polyedra 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 Term.—Structural Drawing.—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.
