Which do you suppose exerts more pressure on the gound- an elephant or a woman standing on spike heels?

Lets do a quick calculation.
A typical woman would way in at about 70 kg. If she is wearing spike heels, standing on her heels, her total surface area conveying her weight to the floor would be the sum of the area of the heels. Let's say her spike heels each have a surface area of 0,16 cm2
This would be possible is say they were 0,4 cm x 0,4 cm.
That would mean she has a total pressure of 70 kg on 0,16 cm2. This is the same as 437,5 kg pr. cm2.
Now for the elephant!
A male African elephant can weigh as much as 4.500 - 6.000 kg. For the sake of this calculation lets say the elephant weighs 5.000 kg.
An elephants foot can be as large as 40-50 cm in length and width. The circumference can be as large as 1,3 m.
From math we know that A = π x r2
We know π, but we need to know the radius, r.
This we could take from the width / length measurements, but we want to find it for a circle that has a circumference of 1.3 m.
Since O = π x d => O / π = d => d = 41,4 cm. This equals a radius of 20,7.
No we can calculate the surface area of 1 elephant foot to be π x 20,72 = 1345, 45 cm2.
Since an elephant has 4 feet, the total surface area will be 5381,8 cm2
This gives the elephant a weight to surface-area of 5000 kg on 5381,8 square centimeters of surface, which equals 0,92 kg /cm2.
Compare this to the womans which was 437,5 kg / cm2. (Though you should keep in mind, that the womans total surface area was only 0.16 cm2).
The answer is: The woman has by far the most pressure on the ground compared to an elephant. Actually she has 470 times as much pressure. This is why you want women to take of their high heels at your party, if you have wooden floors.

What is the pressure exerted by a man standing on one leg?
The pressure exerted by a man standing on one leg is twice the pressure he exerts when standing on two legs
Which exerts greater pressure on the floor standing flat footed or standing on tiptoe?
on tiptoe, because the force acts over less area
Which exerts greater pressure on the floor- standing flat footed or standing on tiptoe?
on tiptoe, because the force acts over less area
Which exerts greater pressure on the floor standing flat-footed or standing on tiptoe?
on tiptoe, because the force acts over less area
Who exerts more pressure on the ground a 500N woman standing in 0.005m high heels or a 500N woman standing in 0.05m work boots?
a women who wears a 500n while standing in 0.5m work boots.
What is exerting pressure?
Force exerts pressure. For example: At the surface of the Earth the column of air in the atmosphere above an area has a mass that exerts a force (due to gravity) on that surface area.
Who exerts more pressure on the ground a 50kg woman standing in high heels or a 50kg woman standing in work boots?
heels bc everything is going into this one little heel but your boots support everything
Describe the reason a fluid exerts pressure on an object immersed in the fluid?
The pressure that a fluid exerts depends on the density and the depth of the fluid.
Under what circumstances a fluid exerts equal pressure in all direction?
Any liquid exerts equal pressure in all directions.
When air exerts a force it is called?
-- Pressure -- Wind
Who exerts more pressure on the ground -a kg women standing in high heels or a kg women standing in work boots?
High heels. The downward force in both cases is the weight of the woman. However, in high heels, the force acts on a relatively small area whereas with work boots the area is larger. As a result, the pressure is greater with high heels.Estimates suggest that a woman of average average mass, wearing stiletto heels with an area of 1 cm^2, will exert more than 10 times the pressure exerted by a 4 ton elephant standing on one foot.
How do you know that air exerts pressure?
Because the pressure can be measured with a barometer.
