Four masses of 630 g are placed at the vertices of a square of side length . Determine the coordinates of the center of gravity of the system relative to the axes and .
The figure shows a system of point masses . The mass of each point is detailed in the table. Find the coordinates of the center of gravity of the system.
The equilateral triangle in the figure has a side length is 36 cm. Point is the intersection of its medians (its centroid) and is the midpoint of . Masses of magnitudes 15 g, 27 g, 40 g, 12 g, and 50 g are fixed at the points , , , , and respectively. Determine the coordinates of the centre of gravity of the system.
