CAD 270 - Machine Elements and Design Credits: 4 Lecture Contact Hours: 3 Lab Contact Hours: 1 Description: This course is designed to introduce the student to the various machine elements and the mechanical/working relationship between elements that make up a mechanism. The machine element concepts covered include fasteners, gears, cams, linkages and bearings. The introduction to the design process includes problem definition, needs analysis, design/performance objectives, cost analysis, design alternatives, feasibility analysis and design selection. Simulation is used to test design proposals for strength and reliability.
Prerequisites: CAD 210 or CAD 220 or CAD 230 . Corequisites: None. Recommended: None.
Course Category: Occupational This Course is Typically Offered: Fall Only Check Course Availability
