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.
This is done so that the force can be used to do work. All mechanical machines are made by combining simple machines. See the fact file below for more information about simple machines. Remove these ads. 1  There are six basic types of simple machines: wheel & axle, pulley, lever, inclined plane, wedge and screw. 2  All simple machines either alter the directions of forces applied to them or multiply their effects.
