## Homework Statement

the theory behind Parallel axis theorem

## Homework Equations

parallel axis theorem:Io=Ig+md²

Radius of Gyration=Ig=m*K²

## The Attempt at a Solution

ok folks If I understand this theory correctly the radius of gyration is the radius or distance from the axis of rotation to the center of the AREA

the parallel axis then takes this area into account and converts the equation to account for the area and the mass.

I am trying to teach myself dynamics before I pay for another course at college and bomb out because the professors don't explain anything...

is this a correct understanding? if not can you help me?
