Dear Baba
parallel axis theorem:
The moment of inertia about the axis z is given by:
where:
is the moment of inertia of the object about an axis passing through its centre of mass and parallel to the z axis;
is the object's mass;
is the perpendicular distance between the two axes- perpendicular axis theorem: The perpendicular axis theorem states that if body lies in XY plane then
- IZ = IX + IY
- where,
- IX be the moment of inertia of the body about the X axis;
- IY be the moment of inertia of the body about the Y axis; and
- IZ be the moment of inertia of the body about the Z axis
- The 3 axis X, Y and Z are mutually perpendicular to each other.
- All the best

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
