Rubberbands & Engineering
By Barb Stephens
Rubberband Strength
One of the requirements for engineer is to make a catapult. This requires the
use of a rubber band or two, or a piece of tire inner tube. The rubber band is
"elastic" and it stretches, but then returns to it's original shape. Before
using materials in building, engineers must know the characteristics. Does it
expand or contract? Is it weak or strong? Does it burn or not?
You can try an experiment to learn more of the
characteristics of rubber bands and other elastic material. Get a collection
of different sized rubber bands. Measure them for length, width and thickness
(if you can). Make a chart that shows this information and mark each rubber
band clearly so you know which is which. (Using colored rubberbands is best.)
With each rubber band, attach one end to a cup
hook that is screwed into a board. Attach the other end to a known weight. How
far down does each rubber band stretch? Does its thickness change? Does its
width change? Which rubberband is the strongest? Which rubberband is the
weakest? How can you tell?
