    Moment of mass

    For vertical strips :
    <br />
  M(y-axis)=\int_a^bx\rho[f(x)-g(x)] dx<br />
    M(x-axis)=\frac{1}{2}\rho\int_a^b[f(x)+g(x)][f(x)-g(x)]dx

    For Horizontal strips :

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


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


    Guys l would like to know if these are the correct formulas in this different circumstances. I am not quite sure.
