During National Engineers Week 1999 we celebrate the profession that connects us to people, places and things around the globe. We communicate via the Internet, telephone and television. We look inside the human body and search in distant galaxies. Engineers remember our past, manage our present, and define our future.

Every student coming to the Fair should have a chance to talk to working engineers, and explore with them all the latest technology and the system techniques we use to solve the problems of aircraft, automotive design, civil construction, electrical and electronic devices and systems, manufacturing methodology, welding technology, and transportation systems of every kind. What role will you play? Contact your own Society’s PSEC rep. and help to plan your own booth.

There will be hands-on science explorations with guidance from the engineers and teachers involved in Science Olympiad, World in Motion, Future Engineers and Scientists of America, Math Counts, and from Bluebills Volunteers.

In November we sent you Fair “99 flyers and posters to read and deliver to the teachers and schools of your choice. Please don’t delay any longer, make a telephone contact now and make sure they get into the right hands!

Children who learn because they simply want to work things out because it matters to them, are far more resilient and determined when they face problems than children who seek external rewards.

The brain is essentially a survival system; it takes more seriously those things which matter to it. Emotional well-being may well be more essential to the brain for survival than intellectual well-being.

All learning takes place on the boundary between order and chaos. Unless you are willing to risk stepping over and back again, nothing productive will happen.

If the dynamics of the system are too chaotic no learning occurs , because there is not enough stability to conserve the new information. If the dynamics are too static, no learning occurs because no change occurs in response to the new information.

Newton's Laws:
A body will remain at rest, or in a state of constant motion - unless a force is applied.
Action and reaction are equal and opposite.
The acceleration of a body is proportional to the amount of force applied.

Mass and Inertia:

Inertia (stay-put force) of a body is proportional to its mass
Rotational inertia of a body is proportional to its mass, multiplied by its radius of gyration from the center of rotation.
Rotational rate of acceleration of a body is proportional to the net amount of torque (twisting force) applied.

Energy:

Energy cannot be destroyed, it can only be transformed.
Energy can be stored in many forms - (mechanical, electrical, chemical etc.)
Energy can be potential (stationary) or kinetic (moving)
Momentum is the energy of a body in motion

Force and Friction

A force is a push or a pull or a twist.
- it can be potential (stationary) or kinetic (moving)
Friction is a force that opposes motion.
Friction can be reduced by lubrication
- liquid, gaseous, solid, colloidal)
Rolling friction is usually smaller than sliding friction

Work

Work is force multiplied by the distance moved

Power is work divided by time
