+// A hollow right circular cylinder of radius 800 mm is open at both ends and rests on a smooth horizontal plane. Inside the cylinder there are two spheres having weights 1 kN and 3 kN and radii 400 mm and 600 mm, respectively. The lower sphere also rests on the horizontal plane. 
+// Join the centres of spheres, O1 and O2 and drop O1D perpendicular to horizontal through O2.
