Chapter 8: Moments of Inertia
"Quantities called moments of inertia arise repeatedly in analyses of engineering problems. Moments of
inertia of area are used in the study of distribute forces and in calculating deflections of beams. The
moment exerted by the pressure on a submerged flat plate can be expressed in terms of the moments
of inertia of the plate's area. In dynamics, mass moments of inertia are used in calculating the
rotational motions of objects. We show how to calculate the moments of inertia of simple areas and
objects and then sue results called parallel-axis theorems to calculate moments of inertia of more
complex areas and objects."
