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.
A lever, one of the six simple machines.copyrightCopyright Â© U.S. Department of Transportation, Federal Highway Administration, http://www.fhwa.dot.gov/environment/fspubs/05232810/page16.htm. Students are introduced to three of the six simple machines used by many engineers: lever, pulley, and wheel-and-axle. In general, engineers use the lever to magnify the force applied to an object, the pulley to lift heavy loads over a vertical path, and the wheel-and-axle to magnify the torque applied to an object. The mechanical advantage of these machines helps determine their ability to make work easier or make work faster.
