The Mechanical Advantage is the ratio of the force needed to lift an object using the simple machine divided by the weight of the object
The product of force times the distance the force was directed in, is called "work".The relationship between distance and force is that, when using a simple machine, to move an object it requires less force to move an object a farther distance when using a simple machine than moving an object without a simple machine.The relationship between distance and force is that, when using a simple machine, to move an object it requires less force to move an object a farther distance when using a simple machine than moving an object without a simple machine.Addition: "Using a Force (y-axis) over Distance (x-axis), the Work done can be estimated by calculating the area under the graphed line." -Arian.
A pulley is a simple machine that changes the direction of the force needed to move an object without changing the amount of force required. By using a pulley, you can apply a downward force to lift an object upwards.
A simple machine is mechanical device that is non-powered. It changes the direction of a force. Some examples of a simple machine include a wheel and axle, a wedge, and a pulley.

No, it is level to the ground, hence not an inclined plane. And mainly, it provides no mechanical advantage. To use Wikipedia's definition of a simple machine, a balance beam does not "chang[e] the direction or magnitude of a force" and is therefore not a simple machine.

You are using a wheel and axle simple machine when you twist a doorknob. The wheel (the doorknob) rotates on the axle (the spindle), allowing you to easily open or close the door.
my results are that simple machines work by using force and some work.
A complex machine is a machine using more than one simple machine for its operation. A bicycle is a complex machine, using a lever for steering (handlebars), wheel and axle, inclined plane (the threads on bolts), and a pulley (chain on sprockets).
the work a machine does is the work output what it takes to do the work is the work input
