ME Program Educational Objectives:        


Broad and in-depth knowledge of engineering science and principles in the major fields of Mechanical Engineering for effective engineering practice, professional growth, and as a base for life-long learning.

Hands-on experience with available instruments and lab techniques to bridge classroom learning and practical, “real-life” problems.

The ability to utilize analytical and experimental methods and modern computer technology for decision-making and engineering design and to solve realistic engineering problems.

The ability to work effectively with others in a team while simultaneously maintaining independent and creative thought.

The ability to communicate effectively and to articulate technical matters using verbal, written, and graphic techniques.

An adequate background to pursue graduate studies in engineering and other fields.

A sense of professional and social responsibility, including a commitment to protect both occupational and public health and safety, developed through consideration of moral, social, and ethical paradigms related to the engineering profession and practice.
