Introduction
In previous chapters, the forces were considered to act at a point.
UNIT - III Centroid Syllabus: Centroids of lines and areas - symmetrical and unsymmetrical shapes, Determination of Centroids by Integration, Theorems of Pappus-Guldinus, Distributed Loads on Beams, Centre of Gravity of a Three Dimensional Body, Centroid of a Volume, Composite Bodies, Determination of Centroids of Volumes by Integration. Introduction • In previous chapters, the forces were considered to act at a point. • However, in actual practical applications such forces do not exist. The forces are distributed over some finite area and can be replaced by an equivalent single resultant force acting through a point. • For example, the gravitational force acts on each and every particle of an object. All these forces, distributed over the entire object, can be replaced by a single force acting through a point. • In this chapter we discuss the methods to replace distributed forces by a single force acting through a point.
