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 kinds of simple machines: the lever, the pulley, the wheel and axle, the inclined plane, the wedge, and the screw.   Everyday workWe all do work in our daily lives and we all use simple machines every day. Work as defined by science is force acting upon an object in order to move it across a distance.
