punto G?

"In general, reference to the centre of gravity of the body means a single point located somewhere in the abdomen, where the whole body should balance assuming that it remained in a symmetrical, rigid state. In reality, each movable part of the body has its own C of G and, depending upon where each part is at any one time, the overall C of G will be located differently and not remain in one place. While it is neither practical nor possible, whithin this book, to demonstrate the mathematics required to establish the precise location of the overall C of G, it is necessary to recognise this fact."
