1. Textiles

   • Fibres
     • 3 stages of processing fibres
       • SPINNING: Fibres are spun into yarn
         • WEAVING OR KNITTING: Yarns become fabrics
           • FINISHING: Fabrics are finished to make them more useful
     • Types of fibres
       • Synthetic fibres
         • Nylon
         • Acrylic
         • Polyester

     • different types of forces
       • Tension: The object is pulled from both sides. ex. tug of war
       • Torsion: the object twists on it self
       • Bending: the object bends inwards or outwards
       • Shear: The force comes from above and below, they rub against each other. ex. scissors
       • Compression: forces are applied from the left and right squeezing the object, ex. springs
   • Shell structures
     • Man-made

       • Cups
     • Natural
       • Animals with Exoskeletons: crabs
       • Eggs
