Question

An Asian elephant has a weight of 52,900 newtons. This enormous weight is balanced on four feet. In a circus act, these elephants often balance on one foot. The average surface area of a foot pad is 2,920 cm2. What pressure is experienced at the food pad if an elephant balances all its weight on one foot? 0.0551 N/cm2 18.1 N/cm2 52,900 N 1.84 N

Answer 1

Option B,
`18.11 (N)/(cm^(2))`

Step-by-step explanation:

Given-

The average surface area of one foot pad of an elephant is
`2920`
`cm^(2)\\`

Weight of an Asian elephant is
`52900` newton

As we know, pressure is equal to total weight divided by total area of the surface on which it is concentrated.

Thus, pressure on one foot pad of elephant is
`(52900)/(2920) (N)/(cm^(2)) \\`

`= 18.11(N)/(cm^(2))`

Hence, option B is correct answer
