| 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. |
