Question

A cycle is fitted with small brakes and another is fitted with very big brakes. the one which is more effective is

Answer 1

Both the small breaks and the big breaks are equally effective.

• In the small brakes, the area of contact is small.
• In the big breaks, the area of contact with the cycle is larger.
• To decelerate the moving cycle, friction is necessary.
• But, friction does not depend upon the area of contact of the surfaces.
• It only depends upon the nature of the surface and the normal force.
• Therefore, both the small brakes and the big brakes are equally effective.

Answer 2

Answer:

both are equally effective
