Engineering Drawing. Use of drawing instruments and instrument exercises, lettering practice, geometric constructions and problems, orthographic projections and multi-view drawing, primary auxiliary views, and secondary auxiliary views. Two laboratory periods and one lecture period a week. Three quarter hours. Autumn, Winter. Alexander, Atkins, Cutler lb. Elementary Drafting for Forestry Students. Care and use of instruments, lettering, drafing fundamentals. One laboratory period a week. One quarter hour. Autumn. Alexander, Atkins 2. Engineering Drawing. Revolution problems, sections, isometric and oblique drawings, dimensioning principles and limit dimensions, threads and fasteners, working drawings, graphs, and engineering graphics. Prerequisite: Engineering 1. Two laboratory periods and one lecture period a week. Three quarter hours. Winter, Spring. Alexander, Atkins, Cutler 3. Descriptive Geometry. Review of orthographic projection, auxiliary view solutions, solutions by the revolution method; line, plane and point relationships; graphical computations, polyhedrons, curved surfaces, and warped surfaces; analytic solutions, and practical applications. Prerequisite: Engineering 2. One lecture and two laboratory periods a week. Three quarter hours. Spring. Alexander, Atkins, Cutler 4. 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. Cutler ♦A student who transfers to U.S.U. in Engineering should consult his adviser concerning the General Education requirements. In place of three hours of the approved electives, a student transferring to U.S.U. in Mechanical Engineering should take Enginer- ing 4. 113 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. (Not offered 1959-60.) Atkins, Cutler 5. Surveying. A continuation of Engineering 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. One lecture and two laboratory periods a week. Three quarter hours. Winter. Cutler 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 tables. The topographic map is completed. Prerequisite: Engineering 5. One lecture and two field periods a week. Three quarter hours. Spring. Cutler 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.
