They all are strong and resistant to compression or to tension. The strongest materials to the compression are concrete reinforced, steel and iron. The easiest to break in compression it is wood and plastic.
In tension they all are difficult to break less the brick that if it is very easy to fail.
All these materials have extraordinary qualities and are basic elements in the construction of bridges, columns, buildings in addition in the creation of planes, routes of train, among others.
