DEFINITION

Classification: 73/65.01

CENTER OF GRAVITY; TURNING MOMENT; METACENTRIC HEIGHT:

(under the class definition) Subject matter comprising an apparatus or method for determining (a) the point at which the entire weight of a body (e.g., a crank or a craft) may be considered as concentrated so that if supported at such a point the body would remain in equilibrium in any position, or (b) the ratio of the torque, applied to a rigid body free to rotate about a given axis, to the angular acceleration thus produced about that axis, or (c) the point of intersection of a vertical line through the center of buoyancy of a floating body with a vertical line through a new center of buoyancy when the body is displaced.

(1) Note. This subclass covers determination of mass distribution and balance of all bodies save rotors.
