Therefore, if the GGT level is normal in a person with a high ALP, the cause of the elevated ALP is most likely bone disease. The GGT test is sometimes used to help detect liver disease and bile duct obstructions.
Another example of an inclined plane is a wedge. A wedge is an inclined plane that pushes objects apart. An axe, knife and a chisel are wedges because their blades are sloped like an inclined plane. These simple machines multiply the effort that you apply and make it easier to cut things. A saw is another type of wedge.
There are six types of simple machines: lever, pulley, inclined plane, wedge, screw, and wheel and axle. Each machine affects the direction or the amount of effort needed to do work. Most mechanical machines, such as automobiles or power tools, are made up of hundreds of parts. However, no matter how complex a machine is, it is composed of some combination of these six simple machines.
