SESSION II: STRUCTURES AND MACHINES
or what most civil and mechanical engineers design for a living

SATURDAY, November 13 1999 9:00 am - 1:00 p.m.
CALIFORNIA STATE UNIVERSITY, LOS ANGELES
ENGINEERING & TECHNOLOGY BUILDING ROOM C 255E

9 a.m. -11:30 a.m.

  LECTURES AND DEMONSTRATIONS

INTRODUCTION TO MECHANICS:

I. HISTORY:
meet Archimedes , Galileo and Newton.

II. STATICS:
learn about bodies at rest under influence of forces (why you can not move the refrigerator when you push it, while you can do it if you put the wheels on it).

FORCES:
action of one body on another: contact forces (push and pull)and forces at a distance (gravity, magnetic forces)

MOMENTUM:
forces and perpendicular distances make bodies turn ( learn the best way to open the door, why wrenches with long handle can turn the tough nuts). Learn what every kid knows and engineers call Mechanical Advantage .

III. NEWTON'S LAWS:
action of balanced forces on the particle, acceleration and action and reaction (why apple falls down from tree, why you weigh much less on the moon, fisherman pushes against dock to move his boat away from it).

IV. DYNAMICS:
work, energy, power. Experiment with pulleys to see how you can raise ta large load with a small force (no, you can not get it free, you have to put equal or greater amount of work to do it.) (Perpetual motion, or free lunch, do not exist, unfortunately).

11:30 p.m.-12: a.m. LUNCH: Bring your own.
12:00-1:00 p.m CONTEST: Design A tower to hold coke can using popsicles and rubber bands. Tallest tower made with fewest sticks wins the prize. To get the prize you HAVE TO WAIT TILL LAST SESSION.
