## Homework Statement

Guys l would like a clarification on the formulas for calculating the moment of mass.

## 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]
