The course includes study of and practice in lettering, line work, projection, conventions, tracing, sketching, shop standards, the use of notes, the reading of blue prints, the reading of layout drawings, pictorial representation, developments, and checking as applied to commercial engineering drawing. _Text: Freshman Engineering Drawing Notes._ ME 2 Engineering Drawing. Prerequisite ME 1. The principles laid down in the previous year’s work are applied to a series of problems in structural drafting, concrete work, gear drawing developments, and welded steel work. Such additional work in descriptive geometry as is necessary for each drawing is given as the work develops. An opportunity is given to learn modern drafting practice, the way a drafting room is managed, and to develop the basis for future courses in design and engineering. _Text: Sophomore Engineering Drawing Notes._ ME 7 Shop Practice. A course for sophomore mechanical students, given in two parts. Part 1--Surveying and Machine Layout. Three hours a week for half a semester are devoted to laboratory work in machine layout. This includes surveys of existing equipment and exercises in establishing lines and elevations for setting machines and equipment. Part 2--Machine Tools. Three hours a week for half a semester are devoted to a laboratory course in machine tool practice. Experiments are carried out in the machine shop and visits are made to industrial shops. _Text: Busse, “Surveying Notes”; “Shop Notes”, Turner, “Machine Tool Work”._ 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. _Text: Schwamb, Merrill and James, “Elements of 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. _Text: Faires, “Design of Machine Elements”, Fairman and Cutshall, “Graphic Statics”._
