Physical/Compound pendulum Calculator

I want to calculate
Center of Mass or Moment of Inertia(I) = kg-m2
Mass(M) = kg
Acceleration of Gravity(g) = m/s2
Distance from Center of Mass to Pivot(D) = m
Period(T) = s
 

The physical pendulum also called compound pendulum is any swinging rigid body free to rotate about a fixed horizontal axis. The animation below is a pendulum.

Physical Pendulum formula

Period: T2 = 4*PI2*I / MgD

where, D = Distance from Center of Mass to Pivot, g = Acceleration of Gravity, M = Mass, I = Center of Mass or Moment of Inertia, T = Period.

For example, when Pi is 3.14, Center of mass or moment of Inertia is 2, Mass is 3, Distance is 4, then T = 0.82S.
