QUESTION:-
1. Ramesh finds out that his bicycle's gear has started making noise. So, he applied oil to the gear to
- (a) increase friction
- (b) decrease friction
- (d) clean the gear
- (d) increase sound
ANSWER:-
- (b) decrease friction
EXPLANATION:-
- The force acting between two surfaces in contact and trying to oppose the motion of one surface over the other is called the Force Of Friction.
- Force of friction always opposes the motion of one surface over the other and tries to stop the movement.
- The Bicycle's Gear wears out due to friction between the parts. A rough surface provides more force of friction as compared to a smooth surface. Due to the wearing of gears, noise is produced. To reduce the sound, the force of friction is needed to be reduced. As we know, a smooth surface has less force of friction so he applied oil which makes the surface smoother to decrease friction.
