(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

For my control system course i need to derive differential equation and period of a physical pendulum.

Pendulum rod's mass is m, length is l and has a spherical mass M

2. Relevant equations

i need relevent equatins so obviously :D

3. The attempt at a solution

i know that i should use stoke's equation for air firicition but i couldnt find out how.

in some posts period of a pysical pendulum is given but i need to solve max. angle

Thank andd sorry about my crappy englisf.İ hope i can define my question
