Center of mass and distance

  1. Dec 10, 2003 #1
    A circular hole of diameter 11.1 cm is cut out of a uniform square of sheet metal having sides 22.2 cm, as in the figure. What is the distance between the center of mass and the center of the sqaure?

    i need some serious help with cm, i dont get this at all.

    U might consider The removed part as negative mass

    Where is the circular hole located (no fig shown)

    If it is removed from centre than the CM wont change

    top right corner of the sqaure

    since considering Centre of square as origin

    [tex]X_{cm}= - \frac{\pi 11.1}{32}[/tex]
    [tex]Y_{cm}= - \frac{\pi 11.1}{32}[/tex]

    where did the 32 come from?
