a 5-meter ramp lifts objects to a height of 0.75 meters.What is the mechanical advantage of the ramp?

coldgirl [10]

This is an Engineering question, and the answer is reasonably simple. The mechanical advantage is given by:

MA = $\frac{Distance 1}{Distance 2}$ on a lever or ramp system.

MA = $\frac{5}{0.75}$

MA = 6.67 (there are no units, as MA is a ratio)
