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.
The wheel and axle is one of the simple six machines, the others being the lever, the pulley, the inclined plane, the wedge and the screw. Through the looking glass After a demonstration of three simple machines--the lever, the inclined plane (wedge), and the axle--the children were up for the task. Little people + simple machines = future engineers + big jobs The screw is actually an inclined plane or wedge that's wound spirally around a cylinder in a helical form.
