A100 kg (220 lb) person stands on a 1 m diameter platform and raises a 1000 kg (2200 lb) car. what is the least diameter of the platform the car is on?

The minimum diameter of other platform is 3.162 meters.

Explanation:

We shall use Principle of transmission of pressure to solve the problem

The Principle of transmission of pressure states that any increase in pressure in a fluid is increased throughout the whole fluid

Mathematically we have

Increase in pressure due to person of mass 100 kg standing on a platform of diameter 1 meter equals

The increase in pressure shall be equal to the pressure applied to the car

Thus to just raise the car we have

where

is the area of platform 2

thus equating the values we get
