When designing you will need to choose appropriate materials to make your design from. There are many different types of materials but some are more suitable than others for a variety of reasons. Here is a selection of those reasons. STRONG – The material will resist – Tension forces -Compression forces -Torsion forces -Shear Forces TOUGH – The material can withstand shock (eg Hammer Blows) BRITTLE – The material will break easily if subject to slight shock or force HARD – The material is long lasting by being resistant to wear, weather, heat etc. WEIGHT – Light – Heavy EASY TO WORK WITH – Cutting – Drilling – Smoothing – Fixing / assembling /gluing – Finishing, (eg Paint, Varnish etc) SAFETY – Non – Toxic – non – Flammable – Not Sharp etc.
COST – Cheap – Dear TIME ATTRACTIVE – Colour – Pattern – Texture By considering these factors the advantages that certain materials present can be compared and these can also be considered against the disadvantages. Materials Available For Your Project Wood SOFTWOOD – Redwood (Scots Pine) HARDWOOD – Beech – Elm – Oak (European) – Sycamore – Mahogany MANUFACTURED – Plywood – Hardboard – Blockboard – Chipboard – M. D. F METAL FERROUS – Mild Steel NON – FERROUS – Copper – Brass – Aluminium – TinPlate PLASTIC – ACRYLIC – POLYSTYRENE When designing you will need to choose appropriate materials to make your design from.
