This course covers the four fundamental operations on integers, rational numbers, and real numbers. It includes the study of weights and measures, exponents and radicals, factoring, and linear equations, with an emphasis on technical applications.
This course is a continuation of MA105 Technical Mathematics 1, with further topics from algebra as well as from geometry and trigonometry, and an emphasis on technical applications. Prerequisite: MA105 Technical Mathematics 1.
An introductory course designed to provide the student with basic knowledge and skills necessary for personal growth in any electrical service technician program. The course includes an in-depth study of electron theory, Ohm's Law, series and parallel circuits, electrical energy and power relationships. Methods of generation of electromotive force, electromagnetism, motor principles and capacitance as these apply to D.C. circuits are included in the course. Uses, construction and calibration of voltmeters, ammeters and wattmeters are also investigated. Corequisite: MA105 Technical Mathematics 1, or permission of instructor. (Fall semester only)
Introduction to the theory and practices of metal removal, as practiced in industry. The set-up and safe operation of conventional machine tools is stressed, along with their capabilities and limitations. Common processes such as drilling, grinding, milling, threading and turning will be utilized on a lab project. Topics include: speeds and feeds, metal cutting theory, cutting fluids, selection of tooling, fixturing, precision measurement, layout procedures and N/C programming introduction. Prerequisites: MT121 Mechanical Drafting or MT101 Engineering Drawing, (or equivalent), MA105 Technical Mathematics 1 or permission of instructor. (Spring semester only)
This course covers the basic physics as applied to the refrigeration and air conditioning industry. Flaring and soldering techniques, compressor construction and domestic refrigeration, including characteristics of automatic controls as applied to domestic refrigeration. Prerequisites: MA105 Technical Mathematics 1 and ET101 Technical Electricity 1, or permission of instructor. (Spring semester only)
