WebCentre of gravity of a body is defined as the point through which the whole weight of the body acts. A body can have only one centre of gravity for all positions of the body. It is represented or denoted by C.G. or G. Consider the following lamina. Let’s assume that it has been exposed to gravitational field. Webthe gravity on Earth. Any value of N (artifical gravity) can be selected by adjusting v and r. For example, if we want a space station spinning at one revolution per minute to have an apparent gravity equal to that on Earth, what should be the radius of the station? T = 2 pr v r = Tv 2 p mg = mv 2 r v = rg r = T rg 2 p r = T g 2 p r = T 2 g 4 ...

This causes a decrease in the venous return to the heart, which in turn causes a decrease in the cardiac output. This can result in a reduction in the amount of oxygen that is delivered around the body, which can lead to fatigue as well as a reduction in ...
WebThe Centre of gravity is a theoretical point in the body where the body’s total weight is thought to be concentrated. It is important to know the centre of gravity because it predicts the behaviour of a moving body when acted on by gravity. It is also useful in designing static structures such as buildings and bridges.
