Moment of mass

  1. Apr 19, 2009 #1
    1. The problem statement, all variables and given/known data
    Guys l would like a clarification on the formulas for calculating the moment of mass.




    3. The attempt at a solution


    For vertical strips :

    [tex]M(y-axis)=\int_a^bx\rho[f(x)-g(x)] dx[/tex]

    [tex]M(x-axis)=\frac{1}{2}\rho\int_a^b[f(x)+g(x)][f(x)-g(x)]dx[/tex]

    For Horizontal strips :


    [tex]M(y-axis)=\frac{1}{2}\rho\int_a^b[f(y)+g(y)][f(y)-g(y)]dy[/tex]


    [tex]M(x-axis)=\int_a^bx\rho[f(y)-g(y)]dy[/tex]
