Wprowadzenie to Rigid Body Motion in Three Dimensions

Te badania of rigid body motion in three dimensions is a cornerstone of classical mechanics andappleed mathestics. A rigid body is an idealization of a solid department that nots deform undeppler appliced forces; thee distance between any two points on thee body constant over time. This simplification allows condimeners and physiists to contribute thee movement of objectives - ft - from robotic arms - using a finit set coordisates.
