The input to this model is the hydraulic forces reduced at the centre of gravity.
The direction it eventually falls depends very sensitively on its centre of gravity; any small departure triggers a fall in a particular direction.
The horizontal forces can be considered in relation to the motion of the centre of gravity of the user's body.
And not only must the puppeteer 'dance' with his marionette, but he must transpose himself into its centre of gravity.
The stairs give access to four undergraduates' rooms at each floor level, and are positioned at the centre of gravity of the group of rooms.
So too was the concept of a superstructure with a low centre of gravity, broken up into separable units.
The centre of gravity for station 4 was located in an intermediate position between these two groups.
All have moved from agriculture- to being industry or service-based and the centre of gravity has moved from the country to cities.
