Positioners used in wound care are devices that elevate, transfer, place, support, or help change the position of an entire body or individual parts. They utilize air, air-permeable fabrics, fiber fill, foam, gel, or a combination of these components.
What is the definition of reverse fault? A fault along the Earth's crust is identified by the corresponding type of stress that caused its formation. In geology, a stress is defined as the amount of force exerted on a unit of surface area. Generally, shear stress forms transform faults, compressive stress creates reverse faults and tensional stress produces normal faults.
Strain = A change in shape or volume in response to a stress. Stress is the cause, strain is the effect! There are three types of stress: 1) Compressive stress  Forces that squeeze or push toward one another from opposite directions (cause shortening or flattening). 2) Tensional stress  Forces that pull away from one another in opposite directions (cause stretching or extension). 3) Shear stress  Forces that are offset from one another and operate in opposite directions (cause a shear strain). The behavior of rock during stress depends on: 1) The type of rock. 2) The type and amount of stress.
