Examples of Pressure:

1. Skis have a large area to hold up the weight of the skier on the snow.
2. Flat-bottomed shoes are comfortable to wear due to reduced pressure acting on our feet.
3. A sharp knife can cut easily because the very high pressure under the cutting surface is more than the object can withstand.
4. In some situations, a highly concentrated force is useful so a small area of contact is desirable e.g. scissors, knife-edge, nail point, cheese wire, spikes on golf shand oes, and the sharp edge of the spade.
5. In other situations, low pressure is better and so a large area of contact is part of the design e.g. wide tires, schoolbag straps, suitcase handles, and broad feet of elephant and camel.
