Engineering Drawing. The use and care of drawing instruments, instrumental exercises, conventional life, lettering, practice, construction problems and problems in orthographic and projection study. Three laboratory periods a week. Three quarter hours. Autumn, Winter, Spring. Alexander, Atkins lb. Elementary Drafting for Forestry Students. Care and use of instruments, lettering. Drafting fundamentals. One laboratory period a week. One quarter hour. Autumn. Alexander, Atkins 2. Engineering Drawing. Auxiliary projection, revolutions, intersection, developments, perspective, isometric projection, and oblique principles of working drawings. Prerequisite: Engineering 1 or la. Three laboratory periods a week. Three quarter hours. Winter, Spring. Alexander, Atkins 3. Descriptive Geometry. Auxiliary views, fundamental constructions, point line and plane relations, developable surfaces, intersections, and angles between planes. Prerequisite: Engineering 2. One lecture and two laboratory periods a week. Three quarter hours. Spring. Alexander, Atkins 4a. Surveying. The theory and use of surveying equipment, including the chain, plumb-bob, hand level, engineer's level and engineer's transit. This equipment is used to measure horizontal and vertical angles and distances, run traverses, and shoot grades. One lecture and two field periods a week. Prerequisites: Engineering 1, Mathematics 3 or 3a. Three quarter hours. Autumn. Staff 119 4b. Surveying. The theory and use of surveying equipment including the chain, plumb-bob, hand level, engineer's level and engineer's transit as used to measure horizontal and vertical angles and distances, run traverses and shoot grades. Laboratory office practice includes computation of areas, volumes, and curves. One lecture and two field periods or laboratories a week. Three quarter hours. Autumn. Staff 5. Surveying. A continuation of Engineering 4 and 4a, the field periods being replaced by office practice including adjusting and plotting of field data, computation of areas and volumes, earth fill dam volumes, reservoir area-capacity curves, and use of the polar planimeter. Prerequisite: Engineering 4a and 4b. One lecture and two laboratory periods a week. Three quarter hours. Winter. Staff 6. Surveying. A continuation of Engineering 5. Office practice is replaced by field work. A large scale topographic survey is made by running horizontal and vertical control, taking solar observation for meridian, and by shooting details with the transit and plane table. The topographic map is completed. Prerequisite: Engineering 5. One lecture and two field periods a week. Three quarter hours. Spring. Staff 10. Pattern Making. Pattern details, problems in pattern design, and the making of simple and complex patterns to be used in the foundry. One laboratory period a week. One quarter hour. Autumn. Alexander 11. Machine Shop Methods. The theory and practice of machine shop methods. It includes use and exercises with hand tools, and such power machines as lathes, grinders, drill press, and milling machines with exercises in center, face plate and chuck work, turning, tapers, thread cutting, boring, reaming, drilling, slab cutting, gear cutting, grinding, finishing, precision measuring and inspection. One shop period a week. One quarter hour. Autumn, Spring. McCormac 12. Foundry. Foundry processing including molding and melting methods, sand preparation, tempering sand, use of parting sand, core sand, sea coal, and special preparation of foundry equipment. One shop period a week supplemented by lectures and industrial plant visits. One quarter hour. Winter. Staff 13. Forging and Welding. Theory and practice dealing with fluxes, swedging, upsetting, heat treatment, and applications of forge welding to steel and steel alloys. Two periods a week. Two quarter hours. Winter. Staff
