What Does a High Mechanical Advantage Mean

A common trait runs through all forms of machinery: mechanical advantage, or the ratio of force output to force input. … One example of this is the screw: a screw with a high mechanical advantage—that is, one that rewarded the user’s input of effort by yielding an equal or greater output—would be useless.

What does mechanical advantage tell us?

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device trades off input forces against movement to obtain a desired amplification in the output force.

What happens when mechanical advantage increases?

The ideal mechanical advantage (IMA) of an inclined plane is the length of the incline divided by the vertical rise, the so-called run-to-rise ratio. The mechanical advantage increases as the slope of the incline decreases, but then the load will have to be moved a greater distance.
