3 Credit Hours
This course is open to high school and post-secondary level students.
MEC 3489 - Mechanical Systems (3 hrs.)
This course develops students’ understanding of the basic concepts of mechanical physical properties relating to Mechanical Systems. Students will explore these concepts as they relate to mechanical, electrical, fluid (hydraulic and pneumatic), and communications systems, as well as to the operation of commonly used tools and equipment.
This course is designed to help the student develop understanding of the basic concepts of mechanical physical properties relating to Mechanical Systems.
Upon completion of the course, the student will be able to demonstrate proficiency in mechanical, electrical, fluid (hydraulic and pneumatic), and communications systems, as well as the operation of commonly used tools and equipment. They should be able to develop scientific-inquiry skills as they verify accepted laws of physics impacting the technological applications of mechanical systems as it applies to safety and the environment.

Maximum class size:
Based on classroom occupancy.
Course Time Frame:
The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
