THEORY  OF  DISPLACEMENT  –  Archimedes  Principle  (  c287-­‐‑212  BC  )

Page 2: accessory design

 Any  object,  wholly  or  partially  immersed  in  a  fluid,  is  buoyed  up  by  a  force  equal  to  the  weight  of  the  fluid  displaced  by  the  object.

 Where  buoyancy  is  the  apparent  loss  of  weight  of  an  object  when  immersed  in  a  liquid.

Page 3: accessory design

 When  buoyant  force  =  weight  obj  –  it  floats

 When  buoyant  force  <  weight  obj  –  it  sinks

 Volume  of  fluid  displaced  =  Volume  of  the  immersed  object  

 Volume  of  fluid  displaced  =  Mass  of  immersed  object    ONLY  IF  FLOATING

        For  example  -­‐‑  2  Objects  in  water   M  =  V  x  D Vol  obj  =  100  cm

3

Mass  obj  =  270  g Vol  H2O  displaced  =  100  cm3

Vol  obj  =  100  cm3

Mass  obj  =  60  g Vol  H2O  displaced  =  100  cm3 Mass  of  H2O  displaced  =  60  g

 The  material  stored  is  immersed  in  water,  displacing  it  equivalent  to  its  weight,  as  it  is  not  submerged

 As  container  empties  you  can  see  how  much  is  left  inside  by  the  level  of  displacement.
