Question

what might be the mechanical advantage of a ramp?

Answer 1

the work done by both processes is the same for both processes. Let the force required to carry the load straight up be F_vertical and the force required to push the load up the ramp be F_ramp. Let the work done be W. we assume there is no friction.

\[W = F_{vertical} \times h = F_{ramp} \times d\]
the mechanical advantage M = F_ramp/F_vertical, which simplifies to M =d/h.
