How do
compression and tension make things strong?

Introduction
| Think about bridges,
long buildings, tower cranes, airplanes and almost any
other large structure. How can they be made so large and
so strong with materials that don't seem to have enough
strength? The answer to this question by material and
structure engineers is compression and tension. In other
words, these structures are designed in a way that all
forces including weight and wind will be converted to
tensile and compressive forces on the structural
material.
In this project we
will try to find out how compression and tension can
make a bridge or tall building strong.

Project
description
In this project you will design and perform some experiments to
see how compression and tension can result in the strength of a
structure. You will then use the result of your experiments to
build a tall structure that holds about 100 times more than it's
own weight. |
