17 Αυγ 2024 · In this section we develop computational techniques for finding the center of mass and moments of inertia of several types of physical objects, using double integrals for a lamina (flat plate) and triple integrals for a three-dimensional object with variable density.
Center of Mass of an Irregular Object. Where is the center of mass of an “L” shaped, constant density, constant thickness block with the dimensions shown in the illustration? Set the zero, zero location or origin at the lower leftmost corner of the block. Split the block into symmetrical shapes with known centers of mass locations.

Calculate the center of mass of a given system. Apply the center of mass concept in two and three dimensions. Calculate the velocity and acceleration of the center of mass.
In this section we show how the idea of integration as the limit of a sum can be used to find the centre of mass of an object such as a thin plate, like a sheet of metal. Such a plate is also known as a lamina. An understanding of the term ‘moment’ is necessary and so this concept is introduced.

1. The centre of mass of a collection of point masses Suppose we have a collection of masses located at a number of known points along a line. The centre of mass is the point where, for many purposes, all the mass can be assumed to be located. For example, if two objects each of mass m are placed at distances 1 and 2 units from a point O, as
