	inclined plane - Encyclopedia.com
		inclined plane simple machine, consisting of a sloping surface, whose purpose is to reduce the force that must be applied to raise a load.
		The actual mechanical advantage of an inclined plane is the ratio of the load lifted to the force applied; ideally it is equal to the ratio of the length of the sloping plane to its vertical rise.
		An inclined plane whose sloping length is 5 m and whose vertical rise is 1 m has a mechanical advantage of 5; a 300-newton load can be moved up such a plane by a 60-newton force.

	The Inclined Plane - Maillardet's Automaton--Franklin Institute Science Museum
		The inclined plane permits you to overcome a large resistance by applying a relatively small force through a longer distance than the load is to be raised.
		Inclined planes can also be used in reverse to slow things down to a stop.
		Inclined planes can be used to raise or lower objects and as a way to gain or lose momentum.

	Johnstown's Inclined Plane is steeped in history, tragedy -- baltimoresun.com
		Not only was the inclined plane a convenience, it was also designed to save townspeople if another devastating flood should occur, as it did in 1936, when nearly 4,000 people used the railway to get to the safety of higher ground.
		When the town flooded again in 1977, the inclined plane was used to evacuate the town and carried boats, emergency personnel and equipment down to the valley to help in rescue operations.
		With the construction of new roads and interstates over the years, the inclined plane is no longer the fastest and most practical way in and out of the valley of Johnstown.

	Inclined Plane Experiment (Site not responding. Last check: )
		Galileo used his inclined plane, a simple board with a groove down which he rolled a small metal ball, to examine Aristotelian ideas about motion.
		Galileo's inclined plane experiment radically changed these ideas by concentrating on acceleration, a stage of motion ignored by Aristotle and most of his followers.
		We decided to replicate Galileo's inclined plane experiment because it was so fundamental to new concepts of motion in Galileo's time.

	Inclined plane
		An inclined plane is a ramp that reduces the force necessary to overcome the force of gravity when changing the elevation of mass in a gravitational field.
		The ramp or inclined plane was useful in building early stone edifices, in roads and aquaducts, and military assault of fortified positions.
		Typically a canal inclined plane consists of a diagonal slope on which there are rails, and boats are raised between different levels by sailing into watertight "bathtub" type containers which have watertight doors at each end.

	Inclined plane Summary
		Before the advent of inclined planes, levers, pulleys, cranes, gears, and belts, heavy objects had to be hoisted, moved, and positioned by brute force.
		The ramp or inclined plane was useful in building early stone edifices, roads and aqueducts.
		The inclined plane is also in contact with the block, and the contact causes friction.

	Teachers' Domain: Galileo's Inclined Plane
		Galileo's use of the inclined plane to study the motion of objects is one of his most important contributions to science.
		As this video segment from NOVA illustrates, the inclined plane allowed Galileo to accurately measure the effect of gravity on falling objects and develop a universal law describing this effect.
		The inclined plane thus allowed Galileo to accurately measure acceleration with simple instruments and ultimately to prove that, in the absence of other forces such as air resistance, gravity causes all falling objects to accelerate toward Earth at the same rate.

		One mass rests on an inclined plane, and another one is connected to it via a rope that runs over a pulley (we neglect the friction between pulley and rope, though).
		You can use the sliders on the left to change both masses, the angle of the inclined plane, and the coefficients of static and kinetic friction.
		For example, you can study how one mass slides down an inclined plane without friction by simply setting the second mass and the friction coefficients to 0.

		Gradually increase the slope of the plane until the penny first begins to slide down, and record the angle of the inclined plane on the data table below.
		Design another mechanical device, besides the inclined plane, which could be utilized to determine the coefficients of frictional force on various pairs of materials.

	Inclined Plane Efficiency (Site not responding. Last check: )
		If the plane is frictionless, the work done, W, to raise a block of mass m through a height h (g is the acceleration due to gravity = 9.8 m/s^2 = 32 ft/s^2) is W = mgh Notice that this is independent of the angle of the plane.
		If, in the other extreme, the plane is horizontal, the block's height does not change as it is pushed along the (un)inclined plane, but work is done against friction.
		So efficiency can be less than 1 in the case of an inclined plane with friction, but otherwise it is always 1.

		The stones they are working with weigh 3480 N (that's close to 800 pounds) and have to be pulled 100 meters (a little more than the length of a football field) up a steep hill.
		If you looked at the hill in cross section you could see that it is already an inclined plane but it is too steep for us to move our stones.
		When you adjust the length of the inclined plane and click (push), the length of the ramp and the effort force needed to move the stone will be displayed.
