If the body touch the plane in two points, itwill be in equilibrium when the verti-cal through the center of gravity, andthe perpendiculars to the plane at thepoints, are in the same plane.

The pressures on P and Q may be determinedby the theory of parallel forces, and P : Q : W=WQ : WP : PQ, P, Q, and W representing the pressures on the two points andthe weight of the body respectively. If the body touch the line PQ in more than two points,…
