1.) screw, pulley, wheel and axle, inclined plane, wedge, lever

2.)the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour. (joule is J)

3.) The input force (effort) is the amount of effort used to push down on a rod, or pull on a rope in order to move the weight

4.)Output force is the force exerted on an object by a simple machine.
