Compound Pendulum (Physical Pendulum) Calculator

I want to calculate
Moment of inertia (I) = kg-m2
Mass (M) = kg
Gravitational acceleration (g) = m/s2
Center 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 due to gravity

D = Center axis length

A simple pendulum, also known as a mathematical pendulum, has its mass concentrated on an object (regarded as a point mass) and its length remains unchanged.

A compound pendulum, also called a physical pendulum, can have any size or shape, but the size and shape cannot be ignored.
