In order to move a box filled with equipment to the second story loft in the warehouse, several students built a ramp or inclined plane. There was some disagreement on the height and material for the ramp. The loft height was 2.5 meters. Sara suggested a very long ramp, approximately 25 meters long. The other students disagreed, insisting it would take too much effort to push the box that distance and the ramp should be much shorter and steeper. Instead they built a ramp 10 meters in length. What comments would you make to the students based solely on the mechanical advantage of an inclined plane?

Answer:

The longer the ramp, the greater the AMA.

Explanation:

When you are creating devices, mechanical devices like ramps to make a job easier for the human being, you want to create them as efficient and with the most upside possible, in that case when building a ramp the longer the ramp the easier it is to push something upwards on it, because the weight of the object is less taken into consideration as the angle of the ramp becomes smaller.
