A study of the graphic language of engineering and technology to include linework, lettering, geometric construction, orthographic projection, pictorial, sectional and auxiliary views and dimensioning techniques. Laboratory time is divided between technical sketching and drawings produced using AutoCAD software. A study of working drawings as they relate to the mechanical field to include detail, assembly, exploded pictorial and welding drawings. Also included are limits, precision, geometric tolerances and fits of mating parts. Laboratory projects develop and demonstrate graphic skills.
Computer software is used in several analysis and design projects.
Oral presentation required. An introduction to hydraulic and pneumatic fluid power systems, liquid and air distribution systems, and the selection of the system components. A study of the displacements, velocities and accelerations associated with the motion of mechanisms including four bar linkages, cams and gears. Also included is an examination of the dynamic forces generated by the mechanisms. Solutions to dynamics problems are obtained by making use of analytical techniques, using a programmable calculator, as well as appropriate computer software.
