## Homework Statement

Four objects are held in position at the corners of a rectangle by light rods as shown in the figure below. The mass values are given below.

M1 (kg) M2 (kg) M3 (kg) M4 (kg)

3.50 1.50 3.90 1.70

(a) Find the moment of inertia of the system about the x axis.

(b) Find the moment of inertia of the system about the y axis.

(c) Find the moment of inertia of the system about an axis through O and perpendicular to the page.

## Homework Equations

Center of Gravity: sumM1*X1+M1*X2.../M1+M2...

## The Attempt at a Solution

I found the center of gravity for the x-axis to be .037736...how do I find the moment of inertia with that information?
