Which formula correctly represents the velocity ratio?

The formula for velocity ratio is defined as the distance moved by effort divided by the distance moved by load. This relationship illustrates the mechanical advantage provided by a simple machine, where the effort applied can move a load over a different distance.

When effort is applied, it allows for a trade-off between the distance the effort travels and the distance the load moves. Typically, when a machine increases the load's potential to be moved more efficiently, the distance the effort moves may be greater compared to the load's distance, allowing for easier movement of heavier loads.

In practical applications, knowing the velocity ratio is critical for understanding how effectively a machine operates, making it a foundational concept in the analysis of mechanical advantage and efficiency in design technology.

Other options provided do not align with the standard definition of velocity ratio. The first option misplaces the relationship between load and effort, while the second incorrectly frames the comparison by reversing the positions of load and effort. The last option discusses speeds rather than distances, which is a different concept and does not accurately express the velocity ratio.
