7. Why is it difficult to walk on a sandy floor with pencil heels?
Answers
Explanation:
Sand is not that much compacted as compared to normal floor. It is comparatively soft.
Therefore, you feel comfortable waling on sand with shoes that put less pressure on the sand. Such as in case of flat shoes, the pressure is equally distributed to the entire shoes bottom and it helps you stay stable on sand. Since we know
Pressure = force / area
In case of pencil heals, whole mass in concentrated on heals and surface area is small which in turn exerts more pressure on sand and you sink in sand. Which makes it difficult for you to walk on it.
It is difficult to walk on a sandy floor with pencil heels as the heels get sinked in the sand.
- It is so because the area of pencil heels is very less and due to this they exert more pressure on loosely held sand particles.
- It causes the heels to pierce into the sand and it becomes difficult to walk in such a situation.
