Height of Slope (H) / Length of Slope (L). Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. It is calculated as the ratio of the output force produced by a machine to the input force applied to it. In the case of an inclined plane, the mechanical advantage is determined by dividing the length of the slope (L) by its height (H). This gives the ratio of the effort required to lift an object using the inclined plane to the weight of the object being lifted.
