A group of students is designing a wheelchair ramp for their school entrance. According to the concept of a simple machine, which modification would make it easier to push a wheelchair to the same height?
Increasing the length of the ramp while keeping its height constant
For an inclined plane (ramp), increasing its length while keeping the height constant reduces the slope, which reduces the effort needed to push a load to the same height, making the task easier.
Hence, the correct answer is Increasing the length of the ramp while keeping its height constant (C).
