Complete Question
Four small masses of 0.2 kg each are connected by light rods 0.4m long to form a square. What is the moment of inertia of this object for an axis through the middle of the square and parallel to two sides.
Answer:
![I=0.032kgm^2](https://img.qammunity.org/2022/formulas/physics/college/aimygmxu49ea0zpqphsdhklmxw5w959q7t.png)
Step-by-step explanation:
From the question we are told that:
Mass
![m=0.2kg](https://img.qammunity.org/2022/formulas/physics/college/5micvler0im1tdjnq66v7uiw4checeqaic.png)
Length
