What expression represents the ramp advantage?

Explanation:
The ramp provides a mechanical advantage by spreading your push over a longer distance. For an ideal inclined plane, this advantage is captured by the ratio of the ramp’s length to its height, and it also equals how the load compares to the effort you must exert. In other words, length divided by height is the same as weight divided by the force you need to apply to move the object up the ramp. So the expression length of ramp over height of ramp equals weight of object over force required to move object. This means the longer the ramp (for the same rise), the smaller the needed push, since F = W × (H/L). Alternatives that place the forces in the numerator or use a product of dimensions don’t reflect how the incline distributes effort.
