Question asked by Filo student
the arge amount of power loss in engines.
- Polishing : When surfaces are pollshed, friction (Mar- 09,14, May-0 decreases.
- Ball-Bearings : The hard steel balls(called bearing) placed betweer friction into rolling friction hence friction is reduced.
- Lubricants : Lubricants like oil (or) grease which spreads over the surface thereby the friction is reduced.
- Streamlining : By making front portion of vehides in a curved shape State the laws of rolling friction.
