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
