What is a inclined plane in simple machines?
inclined plane, simple machine consisting of a sloping surface, used for raising heavy bodies. The force required to move an object up the incline is less than the weight being raised, discounting friction. The steeper the slope, or incline, the more nearly the required force approaches the actual weight.

What is an inclined plane?
Inclined planes are widely used in the form of loading ramps to load and unload goods on trucks, ships and planes. Wheelchair ramps are used to allow people in wheelchairs to get over vertical obstacles without exceeding their strength. Escalators and slanted conveyor belts are also forms of inclined plane. In a funicular or cable railway a railroad car is pulled up a steep inclined plane using cables. Inclined planes also allow heavy fragile objects, including humans, to be safely lowered down a vertical distance by using the normal force of the plane to reduce the gravitational force. Aircraft evacuation slides allow people to rapidly and safely reach the ground from the height of a passenger airliner .
What is the mechanical advantage of an inclined plane?
The mechanical advantage of an inclined plane depends on its slope, meaning its gradient or steepness. The smaller the slope, the larger the mechanical advantage, and the smaller the force needed to raise a given weight. A plane's slope s is equal to the difference in height between its two ends, or " rise ", divided by its horizontal length, or " run ". It can also be expressed by the angle the plane makes with the horizontal, θ .
How did Simon Stevin get the advantage of the inclined plane?
In 1586, Flemish engineer Simon Stevin (Stevinus) derived the mechanical advantage of the inclined plane by an argument that used a string of beads. He imagined two inclined planes of equal height but different slopes, placed back-to-back (above) as in a prism. A loop of string with beads at equal intervals is draped over the inclined planes, with part hanging down below. The beads resting on the planes act as loads on the planes, held up by the tension force in the string at point T. Stevin's argument goes like this:
What happens when there is friction between the plane and the load?
Where there is friction between the plane and the load, as for example with a heavy box being slid up a ramp, some of the work applied by the input force is dissipated as heat by friction, Wfric, so less work is done on the load. Due to conservation of energy, the sum of the output work and the frictional energy losses is equal to the input work
What is the input force of an inclined plane?
For the inclined plane the output load force is just the gravitational force of the load object on the plane, its weight Fw . The input force is the force Fi exerted on the object, parallel to the plane, to move it up the plane. The mechanical advantage are...
Is a wedge a plane?
Two other simple machines are often considered to be derived from the inclined plane. The wedge can be considered a moving inclined plane or two inclined planes connected at the base. The screw consists of a narrow inclined plane wrapped around a cylinder.
Who proposed the incorrect solution that the input force is proportional to the angle of the plane?
Girolamo Cardano (1570) proposed the incorrect solution that the input force is proportional to the angle of the plane. Then at the end of the 16th century, three correct solutions were published within ten years, by Michael Varro (1584), Simon Stevin (1586), and Galileo Galilee (1592).
What is an inclined plane?
An inclined plane is a flat surface with one edge raised higher than the other. They are useful to help moving heavy items from one level to another easier. They include things like hills, ramps, staircases, and so many more! This book helps kids visualize a whole bunch of inclined planes:
What are the other types of machines?
What are other types of machines we use? Many machines are complex with lots of moving parts, but ALL complex machines are made from six simple machines: inclined plane, wedge, screw, lever, pulley, wheel, and axle. Simple machines have one or no moving parts.
What plane did the third child use?
The next used an inclined plane. The third child used a very gradually sloped inclined plane. The kids observed that using the inclined plane, especially the less steep one, helped the egg go down more slowly and become less cracked.
What is an inclined plane?
Inclined Plane. A simple machine with no moving parts is an inclined plane. Most people call an inclined plane a ramp. Ramps can be found in many business and homes. It is a triangular shaped object with a smooth and even surface, which helps make it easier to move objects to higher or lower surfaces. One end of an inclined plane is higher ...
Which is better, an inclined plane or an inclined plane?
One end of an inclined plane is higher than the other end as shown to the right. The use of an inclined plane is better than trying to lift things directly upwards or vertically.
How does an inclined plane affect the way things move?
For example, moving something will take less work or effort on a ramp with a long distance and a gentle slope. And if there is a steep slope and a shorter distance it will take more effort.
Why do wheelchairs have inclined planes?
A person in a wheelchair may use the gentle slope because it would be much easier for them to move the chair's wheels. Another example of inclined planes is the sliding board often found in playgrounds. Gravity is the force that allows the user to slide down the metal ramp.
Which plane has the mechanical advantage?
However, the second plane has a shorter distance, but it will involve more work or effort. The gentle-sloped plane has the mechanical advantage, meaning less force or effort will be needed.

DESCRIPTION
Investigate how an inclined plane redirects and reduces the force pulling a brick downward, with or without friction. A toy car can apply a variable upward force on the brick, and the mechanical advantage and efficiency of the plane can be determined. A graph of force versus distance illustrates the concept of work.

Overview
History
Inclined planes have been used by people since prehistoric times to move heavy objects. The sloping roads and causeways built by ancient civilizations such as the Romans are examples of early inclined planes that have survived, and show that they understood the value of this device for moving things uphill. The heavy stones used in ancient stone structures such as Stonehenge are believed to have been moved and set in place using inclined planes made of earth, although i…

Frictionless inclined plane
If there is no friction between the object being moved and the plane, the device is called an ideal inclined plane. This condition might be approached if the object is rolling like a barrel, or supported on wheels or casters. Due to conservation of energy, for a frictionless inclined plane the work done on the load lifting it, Wout, is equal to the work done by the input force, Win
Inclined plane with friction
Where there is friction between the plane and the load, as for example with a heavy box being slid up a ramp, some of the work applied by the input force is dissipated as heat by friction, Wfric, so less work is done on the load. Due to conservation of energy, the sum of the output work and the frictional energy losses is equal to the input work
Mechanical advantage using power
The mechanical advantage of an inclined plane is the ratio of the weight of the load on the ramp to the force required to pull it up the ramp. If energy is not dissipated or stored in the movement of the load, then this mechanical advantage can be computed from the dimensions of the ramp.
In order to show this, let the position r of a rail car on along the ramp with an a…
