Of course the length is greater than the height. Take the example of a right angled triangle where the hypotenuse is always greater than the other two arms.
De is the length of the plane. Dr is the height of the plane. So it is impossible to make the length of the plane smaller than the height of the plane. This is why De is always greater than Dr.
The slope of an inclined plane is found by dividing the rise of the plane by the run of the plane. also the ideal mechanical advantage.
length of slope/ height of slope
Lesser the height of inclined plane, and more the length of it, More will be the mechanical advantage of inclined plane i.e less effort would be applied.
Ideal Mechanical Advantage for an Inclined Plane is equal to the length of the incline divided by the height of the incline.
it is due to the fact that the length of an inclined plane(effect arm) is greater than its vertical height(load arm).
De represents length and Dr represents height. De is always greater because length is always greater then height on a plane.
De is the length of the plane. Dr is the height of the plane. So it is impossible to make the length of the plane smaller than the height of the plane. This is why De is always greater than Dr.
The ideal mechanical advantage of an inclined plane is a ratio describing the length one has to travel to raise a load by a desired height. To obtain this ratio, divide the length of the plane's sloped face by the height of the inclined plane. IMA = Slope length / height

Ideal Mechanical Advantage for an Inclined Plane is equal to the length of the incline divided by the height of the incline.
Since the Mechanical Advantage of the inclined plane is inversely proportional to its height, increasing the height would lower your mechanical advantage and lowering the height would increase it.Alternately, mechanical advantage is directlyproportional to an inclined plane's length, therefore increasing the length would increase your mechanical advantage.
the formula for the mechanical advantage of an inclined plane is the length divide by the height.
As an inclined plane gets shorter, the angle gets steeper and the effort becomes greater.
It decreasesThe greater the angle, the steeper the inclination, the less effective it is. The greater the horizontal distance traveled for every unit length of height gained, the greater the mechanical advantage. GO Michael cooper repersentin Monticello
