Mechanical Engineering
Mechanical engineers design, analyze, and develop, control and maintain machines, structures, devices and mechanical systems.
This is the broadest discipline dealing with virtually all productsAutomobilesJet enginesGas turbinesLight/Heavy machinery
BicyclesFluids (also bio-fluid)Power plantsDisk drives

Mechanical Engineers are needed everywhere
Mechanical Engineers are professionals devoted to employing principles of motion, forces and energy.
M.E. are interested in the design, analysis and fabrication of machinery.
Since machines are omnipresent, they work in all fields like Transportation (air, rail, road, water) Communication (electric, voice, video) Manufacture (mills, materials, all products) Power generation and distribution Light and Heavy industries
Mechanical engineers at university teach and prepare next generation engineers.
They impart their knowledge and experience through training students, writing books, papers and conducting new research and creating knowledge.

Basic Curriculum in M.E.
Mechanical Engineers have their roots in millwright as iron smelters, rail road millers in the industrial age.
Today, they require formal training (about 4 years) Some students with two-year college and trained in
Calculus Chemistry Physics Statics and Dynamics
transfer to a four-year university degree program. In the last two years of study, mechanical engineers specialize in
Mechanics and Materials Fluid mechanics and heat transfer Thermodynamics Vibration and Controls Computer aided design/manufacture Capstone Design Project

M.S. and Ph.D. in Mechanical Engineering
Upon B.S., students go to work for companies, governments or pursue graduate (M. S. & Ph. D.) degree.
Typically M.S. takes 2 years and Ph. D. 3 to 4 years to complete. There is also a direct B.S/M.S. program in 5 years. Some industries prefer students with advanced degrees. They
even pay for such degrees. During graduate studies, students typically get financial
assistance in the form of teaching assistantship research assistantship research fellowship scholarship
During M.S. and more so in Ph. D. student specialize in specific fields within mechanical engineering, say Nanomaterials, Finite Element Methods, Controls.

Engineering- Learning is A Life-long Process
Since mechanical engineers work in areas linked to technology, the changes are constantly occurring.
When I went to scale, I used slide rule which is now a part of museum. Computers were never there! Calculators could be owned by only ‘rich and famous’
Beyond formal education, additional education occurs at work, meetings.
Just before graduation, students take Fundamentals of Engineering, the first step to become a Professional Engineers.
Professional engineers (who are involved in design) are mandated to attend continuing education courses to update their knowledge.

Professional Responsibility of Engineers
(Mechanical) Engineers have a responsibility to society to design, build safe, reliable machinery.
Any device built should not pose any threat to the unsuspecting public.
Professional ethics goes beyond prevailing law to use common judgment to determine suitability of a process and product.
It is not sufficient law of the land but the law of universal survival.
Mechanical engineers should also consider long term effects of their design on
Pollution Environment Global warming

Transition from high school to college to engineering college
University is a different ball game from high school Higher standards are expected

At the School of engineering!!
Need different skill sets at university Study skills/strategies Attitudes Communication Skills Time Management techniques
Professors assume that you have the requisite background and skill
Take off from Day 1 Very little time to catch up Semester is too short Homework/Tests start from very beginning and affect the grade Excuses are rarely accepted (Responsibility is yours) Grading is based on relative performance (much talented students
with tough competition)
