Chapter 8 Integral Calculus

Section 8.3 Applications

8.3.1 Introduction

Integral calculus has many varied applications, in particular in science and engineering. Here, the calculation of areas of regions with boundaries described by mathematical functions shall be studied first. This application is not purely mathematical, but is used in the determination of centres of mass, rotational properties of rigid bodies or the bending properties of beams or girders. At the end of this section a few more physical applications are considered.
