Why do AMA and IMA both get closer to 1 for ramp as it gets steeper?

As the ramp becomes steeper, both the angle of inclination and the mechanical advantage change, leading to an increase in the efficiency of the system. The AMA (Actual Mechanical Advantage) approaches 1 because the output force is increasingly aligned with the input force due to the reduced effect of friction and gravitational components. Similarly, the IMA (Ideal Mechanical Advantage) also approaches 1 as the ramp's steepness minimizes the distance traveled for a given height gain, reducing the disparity between theoretical and actual performance. Consequently, both AMA and IMA converge to 1 as the ramp steepens, indicating higher efficiency in force application.
