The force that squeezes a material is a compression force. Think of what happens when we squeeze a spring. We are actually applying a compression force on the spring. Any object kept on the compressed spring is launched into the air, when the compressed spring is released. The compression force is thus made use of in a number of devices. The most common example is the toy dart gun, in which kids apply a compression force on the spring through the dart and when triggered, the compressed spring is released, which releases the dart into air. We also use the compression force in air compressors. These devices suck in the atmospheric air and compresses it to a much smaller volume. The compression force is released when the air is released and can be put to a number of applications.
Hope this helps.
