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. |
