Engineering Mother Daughter Workshop Three: Neda Fabris

SESSION III: ENGINEERING MATERIALS
or how the engineers use and test them

SATURDAY, DEC. 11 1999, 9:00 am - 1:00 p.m.
CALIFORNIA STATE UNIVERSITY LOS ANGELES,
ENGINEERING & TECHNOLOGY BUILDING ROOM C225 E

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

  LECTURES AND DEMONSTRATIONS

INTRODUCTION TO MATERIALS:

I. HISTORY:
materials and civilization: stone, bronze, iron, semiconductor age

II. MATERIALS AND ENGINEERING
learn how engineers adapt materials for society's needs and why they are constantly working on development of new ones. Designers select materials based on their, fabricability, properties, service behavior, cost, availability , recyclability, safety, esthetics and ......

III. MATERIALS AND THEIR PROPERTIES
learn how engineers have grouped materials into: metals, polymers, ceramics,semiconductors and composites. You will find each type in your kitchen and car. See touch, and weigh each in your hand. Find out how the coat hanger can ring like a bell, and how the plastics can show you the stress on the part and where it is going to break. Perform magic trick with balloon!

IV. MECHANICAL PROPERTIES OF MATERIALS
strength, ductility, hardness, toughness, elasticity, plasticity; you know most of these terms, now you will see how the engineers define and determine them. Perform toughness and tensile tests and see how the engineers determine how much material can "take". Do not try this at home!

11:30 p.m.-12: a.m. LUNCH: Holiday pot-luck! Lets' see how we can cook!
12:00-1:00 p.m CONTEST: have fun with the egg drop test ! They are raw eggs and they bungie-jump! The one that comes closest to the ground without committing suicide will win the prize! To get the prize, winner has to wait until last session.
