I am a retired Professor of Mechanical Engineering, who wants to help college students over the "rough spots" in their curricula. Blessed with many years of teaching diversified technical courses, and also much industrial practice, I enjoyed my work very much. Now I would like to help budding students with their problems, for the good of our country's future. My areas of expertise are: strength of materials, kinematics and dynamics of machinery, vibration, thermodynamics, fluid mechanics, heat transfer, control systems, physics and mathematics.
