Catalog Course Description

Focuses on the study of mechanisms, their motion, and related skeletal construction. Calculations are made to determine size and capacity requirements in the design of machine elements. Industrial techniques are applied to detail drawing of various machine parts. Drawing assignments are done extensively on CAD.

Core Course Learning Objectives (Separated)

- Identify critical surfaces and relationships between mating machine parts

- Apply steps for the design of a mechanism in a sequential order

- Differentiate a part that needs to be manufactured for a mechanism from a part that can be purchased or taken from a standard book

- Select a part needed for a mechanism from a commercial catalog or standard book

- Utilize a purchased part in a mechanism using the data from a commercial catalog

- Identify moving parts from static parts in a mechanism

- Identify load-bearing members in a mechanism

- Calculate values and load/power requirements in the design of a mechanism

- Design a mechanism to satisfy a design problem taking into account its function and load/power calculations

- Express a design for a mechanism with a finished mechanical drawing
