Applications of High Pressure

1. Sharp Knife

• can be used to cut an object easily because a small force applied on a very small area of the knife edge can produce a large pressure for cutting the object.

2. Spiked Running Shoes

• can provide a better grip for athletes running on a track because these shoes have spikes that produce large pressure to pierce the track.

3. Ice-skates

• designed to have a small area of contact between the skates and the ice.
• while skating, the weight of the skater produces a large pressure on the ice and melts it, thus enabling the skates to slide easily over a thin film of water.

4. Saws, Chisels and Planes

• have sharp edges to produce a large pressure for cutting.
• nails, pins and needles also have sharp points to produce a large pressure for piercing an object easily.
