1 - A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads.
2 - Worn out tires have several holes and tears and wears in them. Which cannot withstand the pressure of gases. Worn out tyres are discarded as their groves worn out making the surface smooth and harder to stop the car as the friction in less in smooth object
