Moment of Inertia of a Mass

Moment of Inertia of a Mass Formula, Single Mass

\(\large{ I = m \; r^2 }\)

Where:

\(\large{ I }\) = moment of inertia

\(\large{ m }\) = mass

\(\large{ r }\) = radius

    

Moment of Inertia of a Mass Formula, Multiple Masses

\(\large{ I = m_1 \; r_1{^2} + m_2 \; r_2{^2} + m_3 \;  r_3{^2}  }\)

Where:

\(\large{ I }\) = moment of inertia

\(\large{ m_1 }\) = mass

\(\large{ m_2 }\) = mass

\(\large{ m_3}\) = mass

\(\large{ r_1 }\) = radius

\(\large{ r_2 }\) = radius

\(\large{ r_3 }\) = radius
