unit 3.1

• material for wind turbine blades

  fibre glass

  
• second reason for fibre glass

  its corrosion resistant
• third reason for fibre glass

  dimensionally stable, it has a good size to strength ratio
• material for drill chuck guard

  acrylic

  
• first reason for acrylic

  high impact resistance
• second reason for acrylic


  see through
• third reason for acrylic


  corrosion resistant
• material for cylinder head in an internal combustion engine

  cast iron
• first reason for cast iron

  high corrosion resistance
• second reason for cast iron

  high melting point
• third reason for cast iron

  low friction of moving parts
• material for anti-vibration mounts

  rubber
• first reason for rubber

  tear resistant so its longer lasting
• second reason for rubber

  high corrosion resistance
• third reason for rubber

  high tolerance before deformation
• material for centre punch

  mild/tool steel

  
• first reason for mild/tool steel

  very high strength so it dosent easily break
• second reason for steel

  high impact resistance
• third reason for steel

  easy to shape so it can be easily manufactured
• first reason for fibre glass

  fibres are extremely stiff and strong - low density
• first reason for fibre glass

  fibres are stiff and strong so they would have a low density
