PPT-Centre of gravity and centroid

Centre of gravity Known as centre of mass The centre of mass of an object is the point where the whole of the object is assumed to be concentrated Refers to masses or weights The centre of gravity . Centre of gravity (cog). Balance. Stability. The COG is a point in the body where gravity applies it self.. In the body the COG passes between the hips and in front of the sacrum.. The body is in a state of balance when its COG falls within the base of support.. Centroid Principles. Object’s center of gravity or center of mass. Graphically labeled as . Centroid Principles. Point of applied force caused by acceleration due to gravity. Object is in state of equilibrium if balanced along its centroid. Kevin Kelly. Mentor: Peter . Revesz. Brief Introduction. Importance of Project: Beam stability is crucial in CHESS, down to micron-level precision. The beam position is measured using a video imaging system by determining the intensity centroid.. of Gravity. 5 - . 2. Contents. Introduction. Center of Gravity of a 2D Body.
