Physical Pendulum Calculation
Physical Pendulum consists of an actual object that is allowed to rotate freely around a horizontal axis. A physical pendulum is used to regulate a clockwork mechanism. A pendulum is a mass that is attached to a pivot, from which it can swing freely. Pendulum consisting of an actual object allowed rotating freely around a horizontal axis. This is called Physical Pendulum.
T = 2∏√(I/MgD)
Center of Mass or Moment of Inertia:
I = T2 MgD/4 ∏2
M = 4 ∏2I/gDT2
Acceleration of Gravity:
g = 4 ∏2I / MDT2
Distance from Center of Mass to Pivot:
D = 4 ∏2I / Mg T2
T = Period,
I = Center of Mass or Moment of Inertia,
M = Mass,
g = Acceleration of Gravity,
D = Distance from Center of Mass to Pivot.
