37239 Lecture : The center of gravity (CG)
Document Summary
The center of gravity (cg) is the point where the total weight of an object is considered to be concentrated. It is the point where the gravitational force acting on the object can be assumed to act. The center of gravity is important in physics, engineering, and design, as it determines the stability and balance of an object. The location of the center of gravity depends on the shape and mass distribution of the object. For a uniform object with a symmetrical shape, the center of gravity is located at the geometric center of the object. For irregularly shaped objects, the center of gravity may be off-center or located in a region where there is more mass. To determine the center of gravity of an object, one can use a plumb line or a balance. A plumb line is a string with a weight at the end that hangs vertically from the object.
