Bearing:
Bearings are used to convert sliding friction into rolling friction. Metal-upon-metal contact produces large amounts of friction. The friction adds to wear and tear of the metal, producing grinding that slowly degrades the metal. Bearings reduce friction by having the two surfaces roll over each other. They consist of a smooth metal ball or roller that rolls against a smooth inner and outer metal surface. The rollers or balls take the load, allowing by the device to spin. The two basic types of rolling element distinguish the two basic types of rolling bearing:
• ball → ball bearing
• roller → roller bearing
Balls make point contact with the ring raceways. With increasing load acting on the bearing, the contact point becomes an elliptical area. The small contact area provides low rolling friction, which enables ball bearings to accommodate high speeds but also limits their load-carrying capacity.
Rollers make line contact with the ring raceways. With increasing load acting on the bearing, the contact line becomes somewhat rectangular in shape. Because of the larger contact area and the consequently higher friction, a roller bearing can accommodate heavier loads, but lower speeds, than a same-sized ball bearing.
Bearing converts
  • a)
    Rolling friction to sliding friction by reducing area of contact
  • b)
    Sliding friction to rolling friction by increasing area of contact
  • c)
    Rolling friction to sliding friction by increasing area of contact
  • d)
    Sliding friction to rolling friction by decreasing area of contact
Correct answer is option 'D'. Can you explain this answer?

The reason of rolling friction being much less than sliding friction is that while rolling a small portion of the moving object comes in contact with the static object.
