Pressure is determined by dividing force by the contact area. High pressure results from applying force over a small area, like the narrow heel of a stiletto shoe, while low pressure comes from force spread over a larger area, such as an elephant's wide feet. Pressure and moments formulas can be used to calculate and understand pressure in mechanical systems like levers.

2. High and low Pressure
• An elephant exerts relatively low pressure
because the surface area of its feet.
• Where as a woman in stilettos exerts a lot
of pressure because of the low surface
area of the heel.

3. Pressure Formula
• 1m
10m
Pressure=Force/Area
