CHAPTER 11

Centroid and Moment of Inertia

Learning Objectives

By the end of this chapter, the student will be able:

  • To calculate the center of gravity and centroid of various sections
  • To demonstrate the theorem of parallel and perpendicular axes
  • To calculate the mass moment of inertia and second moment of area for different sections
11.1 INTRODUCTION

The centroid is the mean position of elements of area. The coordinates of centriod is mean value of coordinates of all the elemental points in the area. The center of mass is the mean position of elements of mass. In a uniform gravitational field, the gravitational force acts through the center of mass. But, if the gravitational field (hypothetically) is not uniform (in the case of very ...
