Question

Calculate the pressure exerted on the floor when an elephant who weighs 6000 N stands on one foot which has an area of 20 m2

Answer 1

Step-by-step explanation:

P= F/A

= 6000/20

= 300n/m². or 300 pa

Answer 2

P = 300 N/
`m^(2)`

Step-by-step explanation:

Pressure is the rate at which force is applied to an object per unit area.

i.e P =
`(F)/(A)`

where P is the pressure, F is the force applied and A is the area.

When an elephant stands on four feet, the weight is distributed equally to the ground (all things being equal). But if an elephant stands on one foot, the weight is concentrated at a spot on the ground with respect to the area covered by his foot.

Given that, weight = 6000 N = F, and A = 20
`m^(2)`.

Then,

P =
`(6000)/(20)`

= 300

P = 300 N/
`m^(2)`

The pressure exerted on the floor by the elephant is 300 N/
`m^(2)`.
