  Center of Mass.-  
  [01234]

 

 

 
 

(1) The figure shows a laminar piece of metal that consists of 3 sheets A, B, and C, assembled one next to another.  It is known that the density of B is double the density of A, and, that the density of C is the triple of that of A.  Determine the center of mass of the piece.  Measurements are in cm.

Solution.-

For the three pieces A, B and C  the center of mass must be along  y = 5 cm

Horizontal positions of the pieces:   A = 2 cm,    B = 7 cm,    C = 11 cm
