Intended Outcomes for the courseUpon successful completion of this course the student shall have satisfactorily accomplished the goals and objectives listed in the Course Content and Outcome Guides, including;
- Demonstrate a through understanding of threads and fasteners, including; types of threads, types of fasteners, and practices involved when choosing and drawing fasteners.
- Understand basic spring theory and be able to draw a representation of a helical springs.
- Understand and identify types of keys and key sizes.
- Understand working drawings, assemblies and details, and correctly produces both types of drawings.
Course Activities and Design
This course will be presented by means of lecture presentations and coordinated laboratory exercises. Lectures are supplemented with selected reading assignments. Individualized instruction will be provided while the student is working on lab projects. This course utilizes freehand sketching techniques learned in previous drafting classes. The majority of assignments will be completed using the AutoCAD 2-D format.
Outcome Assessment Strategies
Evaluation procedures and grading criteria will be discussed during the first class meeting. Individual and classroom discussions, completed assignments, attendance and classroom participation. exams, quizzes, and worksheets may be used to assess outcomes.
