De represents length and Dr represents height. De is always greater because length is always greater then height on a plane.

Is a knife a lever or incline plane?
A knife is neither a lever nor an inclined plane. It is a simple machine called a wedge.
What is the use of gangplank in the simple machine?
A gangplank is also known as an inclined plane it is a flat surface whose endpoints are at different heights. By moving an object up an inclined plane rather than completely vertical, the amount of force required is reduced, at the expense of increasing the distance the object must travel. The mechanical advantage of an inclined plane is the ratio of the length of the sloped surface to the height it spans; this may also be expressed as the cosecant of the angle between the plane and the horizontal. Note that due to the conservation of energy, the same amount of mechanical energy is required to lift a given object by a given distance, except for losses from friction, but the inclined plane allows the same work to be done with a smaller force exerted over a greater distance.
What do you use less when you pull something up an inclined plane 1 energy 2force 3distance or 4strength?
Distance,You would have to use more energy, force and strength to pull something less distanceif it is up an inclined plane.================================Answer #2:The whole idea of an inclined plane is to give you the ability to raise a load to the sameheight with less force than you'd need if you had to lift it. That's why, if you're smart,you roll a barrel up a ramp instead of lifting it straight up to the dock. In return for usingless force, you have to roll it a longer distance to reach the same height.Energy . . .Same, regardless of how you get it up there. Depends only on the difference in height.Force . . .Less needed if you use an inclined plane. That's why they're useful.Distance . . .More if you use an inclined plane. That's the trade-off.Strength . . .Less required when you use an inclined plane.If you had more strength, you'd just lift it and be done with it.
An inclined plane with one or two sloping sides forms a machine called a?
An inclined plane with one or two sloping sides in called aWEDGE.An example of a wedge would be an axe that you use to chop down a tree.
The advantage of using an iclined plane to lift an object is that it reduces the amount of?
If we use a inclined plane to lift a object then the amount of energy used decreases applied force and wok
When you use an inclined plane you?
DE is greater than DR
Whenever you use an inclined planes?
de is greater than dr
When ever you use an inclined plane?
DE is greater than DR
Whenever you use an inclined plane answer is what?
DE is greater than DR
How can a fixed inclined plane make work easier no it can't.?
inclined plane makes life easier according to the length of the inclined plane.if we use a longer inclined plane,we will use less effort but the distace moved by the effort is greater than the load.but if we use a shorter inclined plane,we need to use more effort but the distance moved by the effort is less than the load.

Is De equal to Dr when you use an inclined 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.
When you use an inclined plane is the length greater than the height?
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.
Would you rather use a really steep inclined plane or lift something on your own and why?
A steep inclined plane is worse than a more flat inclined plane.
Uses of inclined plane?
an inclined plane can be use as ramp
What do people use an inclined plane for?
An inclined plane is useful for rolling something (such as a wheelchair) to a higher or lower level.
An inclined plane is an example of what machine?
The inclined plane is a simple machine because it can be used to use less force.
