Answer 1

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:

$I=0.032kgm^2$

Explanation:

From the question we are told that:

Mass$m=0.2kg$

Length $l=0.4m$

Generally the equation for Inertia is mathematically given by

 $I=md^2$

 $I=0.8*0.20(\frac{0.40}{2})^2$

 $I=0.032kgm^2$
