ME 10 Mechanisms. Prerequisites Math 21, Mech 20.

This course is essentially one of preparation for the
succeeding work in machine design. It includes the study of
links, bands and contact motion; of gears and gear teeth,
epicyclic trains and cams. The recitations and lectures are
supplemented by work in the drafting room where numerous
problems are solved graphically.

Mechanisms”._

ME 14 Machine Design. Prerequisites, ME 2, ME 10 and concurrent with Phys 30.

A course for senior mechanical engineering students.
This course continues the work of the previous year in
Mechanisms. It is outlined to place emphasis on the
strength as well as the motion of machine elements and
their final assembly into the complete machine. The
theory of the graphic solutions of problems is developed
and applied to the analysis of the stress in machines,
including the effects of friction. Both theoretical and
empirical methods are applied to the design of machines.
Its purpose is to instruct students to attack problems in
a direct and orderly manner. Three hours of lectures and
recitations and three hours of drafting room work per week
throughout the year.

ME 16 Machine Design. Prerequisite, ME 2 and Concurrent with Phys 30.

A course in design for non-mechanical students. This course
is subdivided into two parts. Part one deals with general
design and is further divided into two sub-groups. The
first part of this sub-group deals with what is commonly
called Mechanisms and the second part deals with subject
matter which is usually associated with Machine Design
courses which should lead to the ability to proportion
parts of machine elements. Part two is for the purpose of
making the student acquainted with materials and their
characteristics through microscopic examination. In this
part of the work the student is required to examine not
only steels but non-ferrous materials such as brasses and
alloys of aluminum as well. This information coupled with
that given in Course Phys 30 should acquaint the student
with materials from any points of view and should make him
conscious of the important part played by materials in
design work.

ME 18 Graphics and Structural Design. Prerequisite, Phys 30.

The theory of graphic statics is developed. It is then
applied to beams, columns, roof trusses, cranes, etc. The
theory of re-enforced concrete is studied. Design problems
on conveyers, foundations, cranes, chimneys and walls are
worked out. A classroom and drafting room course for senior
mechanical engineering students.

Notes”._

ME 20 Physical Metallurgy. Prerequisite, CH 11.

This course deals with the study of metals by means
of microscopic examination. The subject is introduced
by a discussion which aims to define a metal. This is
followed by an explanation of metallic properties and the
distinction between metals, non-metals, and metalloids. The
standard equilibrium diagrams for binary alloys are then
studied and include the liquid to solid and the solid to
solid transformations that take place. This is followed
by a detailed study of the iron, iron-carbon diagram. The
effect on the microscopic structure due to the addition
of a third element such as nickel, manganese, chromium,
vanadium, tungsten, etc., is then studied.

The equilibrium diagrams of the copper-zinc and aluminum
copper are then studied in detail.

In addition to these discussions the student is required
to prepare for microscopic examination and to take
photo-micrographs of such materials as cast iron, cold
rolled steel, carbon steels, standard S. A. E. Steels such
as nickel, nickel-chromium and molybdenum steels, brasses
and aluminum alloys, etc.

ME 22 Metallography. Prerequisite, ME 20.

This course consists of three hours a week of work in the
Metallographic Laboratory. The subject matter includes
the determination of critical points; calibration of
thermo-couples; study of gas and electric heat treating
furnaces, and the effect of heat treatment on steels,
brasses and alloys of aluminum. The student is required
to prepare specimens for microscopic examination to study
them under the microscope and photograph them in order
to determine whether or not he has secured the required
structures in heat treatment. The change in such physical
properties as hardness is also studied. This course
emphasizes the fact that microscopic examination is a
valuable adjunct rather than a purely laboratory procedure.

ME 30 Thermodynamics. Prerequisites, Math 21, Phys 3.

A Junior Course for mechanical engineering students. The
thermodynamic theory of gases and vapors is studied with
respect to both source of energy and the methods of making
it available. The subject matter includes a study of energy
and its availability; the properties of gases and vapors;
energy changes during expansions and compressions; the
various ideal cycles for converting heat into work; and the
general theory of the flow of fluids. A lecture, recitation
and problem course.

ME 34 Heat Power. Prerequisite, ME 30.

This course consists of applying the principles of
thermodynamics to heat power problems. The subject matter
covered includes combustion, heat transfer, steam engine
principles, air compressors, air engines and refrigeration.

studies and tests of instruments and apparatus used in heat
power engineering and the flow of fluids.
