Question
Which of the following methods can be used to increase friction between two surfaces?
Answer: Option C
:
C
Friction can be increased by making the surface irregular. By using lubricants orpowder between the surfaces, friction is reduced.Ball bearings use rolling friction instead of sliding friction. As rolling friction is less than sliding friction,friction is reduced. However, makingirregularities on the surfaceincreases roughness. As a result of this, friction is increased.
