Formula

Period:
T = 2∏√(I/MgD)

Center of Mass or Moment of Inertia:
I = T2 MgD/4 ∏2

Mass:
M = 4 ∏2I/gDT2

Acceleration of Gravity:
g = 4 ∏2I / MDT2

Distance from Center of Mass to Pivot:
D = 4 ∏2I / Mg T2

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