Answers:

Lever- a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other

Pulley- a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used (typically in combination) to raise heavy weights

Wheel and axle- a simple lifting machine consisting of a rope which unwinds from a wheel on to a cylindrical drum or shaft joined to the wheel to provide mechanical advantage.

Inclined plane- a plane inclined at an angle to the horizontal.

Wedge- a piece of wood, metal, or some other material having one thick end and tapering to a thin edge, that is driven between two objects or parts of an object to secure or separate them.

Screw- a short, slender, sharp-pointed metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.

hope this helps :)
