Four balls of equal radii form a pyramid supported by a smooth horizontal plane surface. The three lower balls are held together by an encircling string as shown. Determine the tensile force S in this string if the weight of each ball is 1000 N and the surfaces of the balls are perfectly smooth. Neglect any initial tension that may be in the string before the top ball is placed upon the other three. B S S
