Question 1 of 5
Inclined Plane

An inclined plane is a simple machine that reduces the force needed to raise an object to a certain height. Work equals force x distance and, by increasing the distance that the object travels, an inclined plane reduces the force necessary to raise it to a particular height. In this case, the mechanical advantage is to make the task easier. An example of an inclined plane is a ramp.

9 What is the mechanical advantage of this inclined plane if the length of the ramp is 27 ft. and the height of the green box is 3 ft.?
