Compound pendulum calculator
Cycle：\(T2 = 4*PI2*I / MgD\)
T = period
I = moment of inertia
M = quality
g = gravity acceleration
D = center axis length
Single pendulum, also called mathematics pendulum, the mass of the pendulum is concentrated on the object (considered as a mass point), and the pendulum length is unchanged.
The compound pendulum, also called the physical pendulum, has the size and shape of the pendulum, and the shape size cannot be ignored.
