# DECREASING PRESSURE BY INCREASING AREA

Share with:

The pressure exerted by a given force can be decreased by increasing the area of contact.

# P=F/A

The equation shows that pressure is inversely proportional to area.

## FOUNDATION OF BUILDINGS

The foundation off building is made more broader than the rest of the building so that the pressure exerted by the weight on earth can be decreased.

## SHOULDER STRAPS OF SCHOOL BAGS

The shoulder straps of school bags are made wider and soft so that the pressure exerted by the heavy bags on shoulders can be reduced. You can feel the paining pressure if you try to replace the broad strap with a narrow one.
