Why inclined planes are called simple machine?
Dear student,
Because when simple machines were defined and classified (literally several centuries ago), inclined planes were included in that classification.
The inclined plane is the simplest of simple machines because to make it work, nothing moves.
The way an inclined plane works is that to save effort, you must move things a greater distance. If you compare the length of a ladder to that of a staircase going to the same height, you'll find the ladder is much shorter. But it takes a lot more effort to climb a ladder than to simply walk up a flight of stairs.
