Find the center of mass for the system of particles of masses 4, 2, 5, and 1 located at the coordinates (1; 2), ( 3; 2), (2; 1), and (4; 0). Point masses of equal size are placed at the vertices of the triangle with coordinates (3; 0), (b; 0), and (0; 6), where b > 3.
Find the center of mass of objects distributed along a line. Locate the center of mass of a thin plate. Use symmetry to help locate the centroid of a thin plate.
Center of mass: The center of mass is the point at which the total mass of a system can be considered to be concentrated for the purpose of analyzing translational motion. It is found by taking the weighted average of the positions of all mass elements in a body or system.
2.6.1 Find the center of mass of objects distributed along a line. 2.6.2 Locate the center of mass of a thin plate. 2.6.3 Use symmetry to help locate the centroid of a thin plate. 2.6.4 Apply the theorem of Pappus for volume.
