Question

9) An elephant puts a force of 36 000 N on its four feet, which each have an area of 1800 cm².

What is the pressure it exerts on the ground?

Answer 1

Step-by-step explanation:

Given:

F = 36 000 H

S₁ = 1 800 cm² = 0.18 m² (The area of the base of one elephant's foot)

n = 4 (number of legs on an elephant )

______________________

p - ?

Support area:

S = n·S₁ = 4·0.18 = 0,72 m²

Pressure:

`p = (F)/(S) \\p = (36000)/(0.72) = 112 500 Pa`

p ≈ 110 kPa
