ELT 782 - Electro-Mechanical Systems Lab

Credits: 2
Lecture Hours: 0
Lab Hours: 4
Practicum Hours: 0
Work Experience: 0
Course Type: Voc/Tech
Application of the basic theories, concepts and principles of electro-mechanical devices. Projects are applications of principles used in business machines, security systems, and medical electronics systems including construction of various examples of compound machines using wheel and axle, gears, levers and belt drives. Projects using basic sensors, pneumatic valves, cylinders and actuators will be constructed. Students will participate in a minimum of four, two-hour, job-shadowing experiences, which may take place outside of regular class time.
Prerequisite: ELT 387 , ELT 388 .
Corequisite: ELT 781
