It is certainly not Mechanical advantage(as it depends on load & effort) ,at the same time it cannot be efficiency, so I think it is velocity ratio
Mridul
Velocity ratio because the presence of friction and weight of moving parts of machine has no effect on its velocity ratiobut decreases mechanical advantage and efficiency

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.
