When was the first inclined plane made

Around B. Between B. Before the advent of inclined planes, levers, pulleys, cranes, gears, and belts, heavy objects had to be hoisted, moved, and positioned by brute force. In other words, since for an inclined plane the height is constant, the force will vary inversely with the distance or length of the inclined plane.

Increasing the length of an inclined plane which decreases the angle of lift will always make a task seem easier, though the total work done, which equals weight x height is always the same no matter what the angle of the inclined plane.

Inclined planes have been in use for a long time. Their earliest known use came about years ago when the Egyptians used them as ramps to construct the great pyramids. The pulley, a grooved wheel turning within a frame, seems pretty simple to us, but years ago it was a pretty big deal to the ancient Mesopotamians who used it to hoist water.

It took a lot more than the wheel, the pulley and the inclined plane to get inclined elevators to where they are now. To learn a little more about the history of inclined lifts and a few tidbits on the systems we produce, check out our blog.
