The inclined plane

The wedge

The screw

The pulley

The wheel and axel

WEDGE

They are triangular tools, normaly of wood, metal, plastic or stone. One of the ends is thick and the other is a sharp edge. Some examples are nails, knives, axes and our theet.

WHEEL AND AXEL

This machine includes two circular objects: a larger disc and a smaller cylinder. They are joined in the center. The disc is called whell and the cylinder is called axel. Some examples are doorknobs, bike wheels, screw drivers or gears

LEVER

Is a beam thet can pivot on a point called fulcrum. The force is called effort and load is called resistance. Ther are three classes of levers: Class 1: seesaw, pliers, scissors, boat, oars, crowbar... Class 2: nutcrackers, wheelbarrows, paper punch... Class 3: teewezers, kitchen tongs...

SCREW

It is an inclined plane around a cylinder with a head. The other end is like a pointed tip. It has ridges for threading. The distance between threads are pitchs. Good examples are bolts, bottle tops, ligth bulbs, faucet taps and cork openers.

PULLEY

IS a simple wheel with a roove in it. It is used to lift up of lower heavy objects.There are three types: Fixed: its axes are fixed Movable: the load is attached to the pulley and both move Compound: a combination of pulleys to reduce the effort

INCLINED PLANE

This is the simplest of the simple machines. An obvious example is the ramp. It help to lift a heavy load to a higher level. The smaller the slope of the ramp, the lower the effort you have to make.
