What is the formula for calculating the mechanical advantage of an inclined plane?

The formula for calculating the mechanical advantage of an inclined plane is derived from the principles of how the inclined plane reduces the effort needed to lift a load. Mechanical advantage is a measure of the force amplification achieved by using a tool, and for an inclined plane, it is expressed as the ratio of the length of the incline to the height it rises.

When using an inclined plane, the effort needed to raise a load vertically is less than lifting it straight up, thanks to the length of the inclined surface. The longer the incline (the length), relative to its height, the easier it is to move an object up the slope. This is reflected mathematically in the formula, where you divide the length of the inclined plane by its height. A longer slope indicates a smaller angle and means that less force is needed to move the same load upwards when compared to lifting it directly.

The other choices do not properly reflect how mechanical advantage is specifically defined for inclined planes. For instance, one may calculate mechanical advantage based on load and effort, but that formula applies to systems such as levers. The calculations that include gravity or load in the context given do not properly address the geometric relationship that exists in inclined planes. Therefore, the correct understanding of mechanical advantage for an
