The H-section, shown in Figure 11.5, can be divided into three parts: left and right parts of area A1 and central part of area A2. The lengths and widths of all the parts of H-section are shown in Figure 11.5. Let the X and Y coordinates pass through origin O. Figure 11.5 H-section The coordinates for centroid can be calculated using the following formula: In the case of…

The U-section shown in Figure 11.4 can be divided into three parts—lower part of area A1 and two upper parts of area A2. The lengths and widths of all the parts of U-section are shown in Figure 11.4. Let the X and Y coordinates pass through origin O. Figure 11.4 U-section The coordinates for centroid can be calculated using the following formula:

In Figure 11.1, an irregular shape is shown for which we want to calculate the centre of gravity, centre of mass, and centroid. Here, our purpose is to differentiate the concepts of these three different terms. It is assumed that the irregular shape, as shown in Figure 11.1, is of uniform thickness, density, and subjected to uniform gravitational field.…

The centroid of an area 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 centre of mass is the mean position of elements of mass. In a uniform gravitational field, the gravitational force acts through the centre of…
