Column-I Column-II
1. Soles of running shoes p. Treads
2. Bicycle q. Spikes
3. Tyres of vehicles r. Brake pads

• A. 1-r ,2-p ,3-q
• B. 1-q, 2-r, 3-p
• C. 1-p, 2-r, 3-q
• D. 1-q, 2-p ,3-r

Answer 1

The correct option is B 1-q, 2-r, 3-p

Spikes are provided in the soles of shoes for a better grip with the ground while walking or running.
Every cycle brake is designed around a brake pad that creates friction with a braking surface located on the cycle’s wheel. When brakes are applied, the brake pad is pushed against the ring of the wheel. This increases friction between the two. Thus resulting in stopping of the bicycle.
The tyres of vehicles have treads in them to increase the friction between the tyre and the road and to prevent skidding.
In all these cases, friction is increased by taking necessary measures as per the requirement.
