What makes the steps of foot over-bridges at Railway Stations to wear out slowly ?
Answers
Answer:
Friction makes the steps of foot "over-bridges" at railway stations to wear out slowly. When walking in the railway station, the "friction" between the shoes and the floor help us to stop from slipping. Necessary grip is provided between the sole and ground due to friction forward reaction is applied to the us.

Wear and tear due to friction
Explanation:
Friction is a phenomenon which resists motion when an object is rubbed against another. Friction actually is helpful in many instances. It helps us walk steadily without slipping. Friction always opposes relative motion between the surfaces in contact with each other. The force of friction between the soul of shoes and the step brings about wear and tear of the surface of the steps of the railway over bridge. Since the amount of foot fall in a railway station is very high, the wear and tear is pretty significant.
