Structures and Simple machines

Structures and Simple Machines

Do you know what is a Structure? Do you know why engineers and architects use them when they want to build a house or a building? Did you know that all the mega engineering buildings are based on simple natural structures?

In this unit you will know what is an effort and a load ūüí™ and which effort can resist the structure.

Eiffel structure construction

How many bridges do you know? And what are their characteristics? Here you will find solutions and how the bridges evolved from beam bridges to suspended bridges. You will learn that triangulation is the key principle. ūüŹó

With the help of this unit you will learn that there are different types of structures as mass structure, shell structure, frame structure, etc.

Finally, you must know how the simple machines work in order to start your new project with structures. You will understand how levers and pulleys work.

If you are in bilingual Technologies 1¬ļESO or 2¬ļESO, you must follow this steps to master the structure’s world and maybe in the future you will become the famour Engineer or Architect that will build incredible bridges, stadiums and pavillions. ūüóľ

Solution to the Listening

Structures bear forces statically, that is, without moving. Mechanisms, on the other hand, allow objects to move. They transmit and transform force and motion from a motor to a receptor. They make work easier and more comfortable for human beings.
