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. S

In an isometric exercise a person places a hand on a scale and pushes vertically downward, keeping the forearm horizontal. This is possible because the triceps muscle applies an upward force M perpendicular to the arm, as the drawing indicates. The forearm weighs 24.0 N and has a center of gravity as indicated. The scale registers 103 N. Determine the magnitude of M. N
