Compound Pendulum (Physical Pendulum) Calculator

I want to calculate
Moment of inertia(I) = kg-m2
Mass(M) = kg
Acceleration due to gravity(g) = m/s2
Central axis length(D) = m
Period(T) = s
 

Compound Pendulum Calculator

Period: T2 = 4*PI2*I / MgD

T = Period

I = Moment of Inertia

M = Mass

g = Acceleration of Gravity

D = Length of Central Axis

Simple pendulum, also known as mathematical pendulum, has a mass concentrated on an object (regarded as a mass point) and a constant length.

Compound pendulum, also known as physical pendulum, has an arbitrary size and shape, and the size and shape cannot be ignored.
