Applications of Low Pressure

1. Bulldozers

• usually moved by a chain with sharp edges in between surfaces of large area to decrease the pressure exerted on the ground.
• in this way, the chin can prevent the bulldozers from sinking into soft ground.

2. Heavy lorries and buses 

• usually fitted with more than four wheels of larger surface area to decrease the pressure exerted on the road.
• this can prevent the tyres from bursting and sinking into the soft ground.

3. Tall buildings

• usually built on a base of large surface area to decrease the pressure and to prevent the buildings from sinking to the ground.

4. Skis

• designed to have a larger surface area to decrease the pressure exerted on the snow.
• this enables the skiers to move smoothly without sinking the snow.
