The center of mass for an object can be thought as the point about which the entire mass of the object is equally distributed. In general, the center of mass and moments of a lamina can be determined using double integrals. However, in certain special cases when the density only depends on one coordinate, the calculations can be performed using single integrals. In this case the centroid of the lamina is determined by formulas. In case of constant density, the centroid has the following coordinates.

In physics, the center of mass of a distribution of mass in space sometimes referred to as the balance point is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body , the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. ## 171875597-Ch-09-Center-of-Gravity-and-Centroid.pdf

In this section, we consider centers of mass also called centroids, under certain conditions and moments. The basic idea of the center of mass is the notion of a balancing point. Many of us have seen performers who spin plates on the ends of sticks. The performers try to keep several of them spinning without allowing any of them to drop. If we look at a single plate without spinning it , there is a sweet spot on the plate where it balances perfectly on the stick. If we put the stick anywhere other than that sweet spot, the plate does not balance and it falls to the ground. The centroid coincides with the center of mass or the center of gravity only if the material of the body is homogenous. (density or specific weight is constant.

## 6.6: Moments and Centers of Mass

In tilt-slab construction , we have a concrete wall with doors and windows cut out which we need to raise into position. We don't want the wall to crack as we raise it, so we need to know the center of mass of the wall. How do we find the center of mass for such an uneven shape?

#### Center of Mass of Thin Plates

This page references the formulas for finding the centroid of several common 2D shapes. In the figures, the centroid is marked as point C. Its position can be determined through the two coordinates x c and y c , in respect to the displayed, in every case, Cartesian system of axes x,y. General formulas for the centroid of any area are provided in the section that follows the table. The centroid of an object represents the average location of all particles of the object. It can be defined for objects of any dimension, such as lines, areas, volumes or even higher dimension objects. It is a purely geometrical property, in contrast to the center of mass also called center of gravity , which takes into account the mass distribution in the object.

Внимание! - скомандовал Фонтейн.

Да вы просто с ума все сошли, что ли? - закричал Джабба.  - Звоните Танкадо. Скажите, что мы сдаемся.

Это обычное явление для компьютерных вирусов, особенно таких, которые поражают крупные блоки информации. Из почты Танкадо Сьюзан знала также, что цепные мутации, обнаруженные Чатрукьяном, безвредны: они являются элементом Цифровой крепости. - Когда я впервые увидел эти цепи, сэр, - говорил Чатрукьян, - я подумал, что фильтры системы Сквозь строй неисправны. Но затем я сделал несколько тестов и обнаружил… - Он остановился, вдруг почувствовав себя не в своей тарелке.  - Я обнаружил, что кто-то обошел систему фильтров вручную.

Я только что выяснил, что ТРАНСТЕКСТ устарел. Все дело в алгоритме, сочинить который оказалось не под силу нашим лучшим криптографам! - Стратмор стукнул кулаком по столу.
