What is Mechanical Engineering?

Turning Ideas into Reality– The broadest of all the engineering disciplines in its range of

activities and functions – Concerned with design, manufacture and operation of a wide

range of components, devices, or systems: • microscopic parts to gigantic gears • more efficient heating, ventilation, refrigeration • laser technology • biomedical applications • automotive industry • computer-aided design, automation, robotics • predictive maintenance and reliability technologies

I decided to major in ME because..

• …“I was always interested in how things worked so I looked at various engineering disciplines and saw that ME affords the best fit for what I wanted in terms of a career choice and interests. The ME curriculum covers some electrical, some civil, some aero.. so I got some practice and have some opportunities in a lot fields.”Senior ME, class of ’09

• …“Mechanical Engineering offered me the most diverse choice in job opportunities. Selecting between medical, military, automotive, and robotics isn’t easy but they all related through mechanics. This choice offers me the opportunity to travel the world and become involved in many different projects.”Robert Newby, Senior ’08

• …“I was good at math and science but mainly I was very interested in how things work and were put together. I have been very curious throughout my life. I was also big into trying to invent new things.”Sophomore ME, class of ‘11

Mechanical Engineering is Cool

Problem: Ozone Depletion

Solution:

Ben & Jerry's

A fire-hydrant-size apparatus called a thermo acoustic freezer made its debut at a Ben & Jerry's in Manhattan. Inside the core of the steel cooling unit, which was attached to a standard ice-cream cabinet, a loudspeaker emitted a 195-decibel screech to keep quarts of ice cream cold. From the outside, you could hear only a soft hum.

Mechanical Engineering is Cool

Problem: Global Warming

Solution

Biomass feedstock is fed into a plasma reactor, which holds one or more plasma arc torches. These plasma torches heat the biomass to roughly 5,000 degrees Celsius. All organic components are transformed into a clean and useful synthetic gas (also known as syngas) containing principally carbon monoxide and hydrogen gases.

Mechanical Engineering at UMD

Imagine a machine so small that it is imperceptible to the human eye. Imagine working machines with gears no bigger than a grain of pollen. Extensive applications for these devices exist in both commercial and defense systems. Recent studies by Systems Planning Corporation have estimated the market for Intelligent Micro-machine based systems to be around $100 Billion/year

Bugs can go places that humans can’t; they cooperate better than almost any other organism; some of them can even fly. It’s those desirable traits that are driving robotics toward a future that looks more like A Bug’s Life than The Jetsons.

Within a decade or so, swarms of mechatronic bugs outfitted with sensors and wireless transceivers will likely be burrowing through the rubble of buildings to search for earthquake survivors and scrabbling over the hull of a spacecraft to repair damage in-flight. They’ll also be the home inspector’s trustiest tool. Imagine the bots scurrying into a house’s plumbing looking for leaks, boring into the insulation in search of asbestos, or checking out that sketchy crawl space.

Flexible Macro-electronics

At the 2007 Pitti Uomo Fashion Show last week, Italian manufacturer ZEGNA, in collaboration with SOLARC (a Berlin based technology firm), presented an article of clothing that can take in solar energy and convert it into electrical energy. Plugging in iPods and mobile devices into one’s clothing to recharge their respective batteries is now an actuality and this is the first generation of “wearable electronics”.

• Diseased valves replaced with artificial prosthesis surgically

• Improperly designed valves increase risk of failure, or causing clot formation (thrombogenesis)

Flow around Prosthetic Heart Valves – (Balaras)

Flow over a Golf Ball

• How do you make a better golf ball?– Dimples play complex role in

flow transition• How does placement affect

drag and lift at typical stroke conditions?

• Computations – Computations require 1 month

on a 1000 processor cluster

Careers in Mechanical

Engineering

Mechanical Engineering at UMD

This course is aimed at providing junior-level undergraduate engineering students with some of the fundamentals needed in developing new products. Through a cooperative education partnership arrangement with Black & Decker, a new product is introduced to the class. Engineers from this corporation present a series of lectures on their real-life experience with this product. The students work as teams to complete assigned course projects related to the new product development. During the redesign Pro/ENGINEER, a method of rapid prototyping, are introduced. These tools aid the students in developing new components and in visualizing their ideas in the learning process.
