Mechanical engineers study the behavior of solids, liquids and gases when forces are applied to them and when they are heated and cooled. They learn how to convert energy efficiently from one form to another. Using these knowledge bases, mechanical engineers play key roles in the design of transportation systems, including automobiles and space vehicles; environmental control systems, including air conditioners and furnaces; manufacturing machinery and processes, including robots; energy conversion technology, including engines and power plants; biomedical devices; and the list goes on. This tremendous breadth in the scope of the mechanical engineering profession gives the mechanical engineer access to employment in every major industry imaginable. Mechanical engineering faculty are highly acclaimed and research areas as diverse as combustion mechanics, the movement of aerosols, rotocrafts, biomedical and aerospace engineering.

500-pound gorilla on the dais

Population growth puts dent in natural resources (http://news-info.wustl.edu/tips/page/normal/12656.html)

Oct. 7, 2008 --
Who can ignore this 500-pound gorilla?
It's a 500-pound gorilla that Robert Criss, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, sees standing on the speaker's dais at political rallies, debates and campaigns. Its name is population growth. "Population growth is driving all of our resource problems, including water and energy. The three are intertwined," Criss says. "The United States has over 305 million people of the 6.7 billion on the planet. We are dividing a finite resource pie among a growing number of people on Earth. We cannot expect to sustain exponential population growth matched by increased per capita use of water and energy. It's troubling. But politicians and religious leaders totally ignore the topic."


Baseball diamond as playground of math and physics

Engineer: Head-first slide is quicker (http://news-info.wustl.edu/tips/page/normal/12487.html)

Sept. 25, 2008 -- With baseball playoffs heating up and the World Series right around the corner, it's guaranteed that fans will see daring slides, both feet-first and head-first, and even slides on bang-bang plays at first. Who gets there faster, the head-first slider or the feet-first? The head-first player, says David A. Peters, Ph.D., the McDonnell Douglas Professor of Engineering at Washington University in St. Louis, and big-time baseball fan. He says it's a matter of the player's center of gravity.

Seminar to address ways to lessen earthquake damage (http://news-info.wustl.edu/news/page/normal/12107.html)

Aug. 11, 2008 --
What should the Midwest do before and after a major earthquake?
The earthquake that hit the lower Midwest on April 18 of this year was a hearty 5.2 on the Richter scale and got the attention of the St. Louis region. What if a larger quake — occurring either in the New Madrid Fault or Wabash Valley Fault — were to hit the region? How would we respond? To address these concerns, the Department of Mechanical, Aerospace and Structural Engineering at Washington University in St. Louis is presenting a series of seminars and workshops on the topic of reducing the damage that could occur if a strong earthquake strikes the area again.

Batter Up: Shattering Sticks Create Peril in MLB Ballparks
Scientific American

July 15, 2008 -- This season, an alarming number of baseball bats have been exploding on contact with pitches -- shooting sharp timber projectiles onto the field and into the stands, where they have struck coaches, fans, players and umpires -- prompting players and management to call for testing that will get to the root of the problem. One theory blames the increased use of maple wood instead of more traditional ash and the players' preference for bats with thinner handles. WUSTL engineering professor Dave Peters comments.


Baseball is built for lefties
Associated Press and 55 others

July 10, 2008 -- Peters is a WUSTL engineering professor who happens to be a baseball nut. He looked at baseball from an engineer's perspective and determined that southpaws have a decided advantage. "Ninety percent of the human population is right-handed, but in baseball 25 percent of the players, both pitchers and hitters, are left-handed," Peters said.


devised a technique on humans that for the first time shows just what the brain does when the skull accelerates
Space Daily

Dec. 16, 2005 -- Mechanical engineers at WUSTL along with collaborators, have devised a technique using MRI technology that shows how the human brain reacts when the skull accelerates. The research shows that as the skull accelerates, the numerous vessels, membranes and nerves at the base of the brain, try to pull away, from the spine leading to a significant deformation in the front of the brain. Philip Bayly, Ph.D., Lilyan and E. Lisle Hughes Professor in Engineering, discussed the group's findings Nov. 10, 2005, at the annual meeting of the National Neurotrauma Society in Washington, DC.
