9.1-9.5

Statics Lecture 32: Mass Moment of Inertia and Area Moment of Inertia

Statics Lecture 33: Area Moment of Inertia -- Calculation

Chapter 9:  Remember back to centroids? (Chapt 5)  This will be similar. 


 I'll let you use Mathematica on the test, this will be a good review of Mathematica!

9.2 Second Moment, or 
Moment of Inertia of an Area

 Example:

Use Mathematica!

Open Mathematica up, and try a few:

HW: 9.1, 9.3

9.4 Polar Moment of Inertia

9.5 Radius of Gyration of an Area

Area between two lines:

HW: 9.15

Polar Moment of Inertia:







HW: 9.28
