1. Structure

   • What's a structure
     • It's a set of elements in a body that are made to resist effects of the forces that acts in it. A structure prevents a body from deforming or breaking.
       • Its purpose is to maintain the object's shape and keep it from breaking when force acts on it
       • Sometimes, the structure is easily identified and others it's harder to distinguish since the whole objevt  forms the structure.

   • Natural and man-made
     • Man-made
       • made to satisfy a need.Example: a mobile phone.

     • Natural
       • are biologically made and not created by humans. They're  living beings, or a result of a natural process. Example: a crab shell.

2. Forces & Loads

   • forces?
     • Anything that can deform a body (static effect) or make it move and stop (dynamic effect). Example: Gravity.

   • Loads?
     • A force that acts on a structure. It can be fixed or variable. Loads produce stress on a structure. The same load can pause different effects depending on multiple important terms such as shape and direction, and trajectory.
     • Fixed or permanent loads
       • Are consistent. Example: the eight of a building.
     • Variable loads
       • vary over time. Example: The traffic lights
