Examples of inclined planes are ramps, sloping roads and hills, plows, chisels, hatchets, carpenter’s planes, and wedges.

It changes the direction of a downward force to a sideways force. As the hammer hits the wedge the downward force is changed to a sideways force pushing the object that the wedge is embedded into sideways. The chisel is a wedge that primarily is used to concentrate the force of a hammer.

Sloping ramps, flyovers, roads on hills and staircases are a few examples of inclined planes.

Answer: When an object rests on a surface like the ramp, the ramp exerts a force called ‘normal force’ on the object, and this force is greater when the angle of incline is smaller. If the ramp is steep, the force of gravity can more easily overcome the force of friction.

A wedge makes work easier by increasing the force applied to the object, although it applies the force over a shorter distance. This gives the wedge a mechanical advantage greater than 1.

One wheel. If you have a single wheel and a rope, a pulley helps you reverse the direction of your lifting force. So, as in the picture below, you pull the rope down to lift the weight up. It doesn’t alter the force in any other way.

Wedges are used to lift heavy objects, separating them from the surface upon which they rest. They can also be used to separate objects, such as blocks of cut stone.

The shovel as a simple machine The shovel consists of a wedge and a lever. The wedge is the shovel’s tip. When you stick a shovel into the earth, the tip transforms the driving force down the handle into forces that comes out from the blade.

A jar lid is a large screw. These ridges hold the jar and the lid together. A wheel and axle is a simple machine made of a rod attached to the center of a wheel. A wheel and axle is a special kind of lever that moves or turns objects.

In “The Nutcracker”, I will incorporate three simple machines. We will have a wheel and axle, a lever and a screw. The wheel and axle will actually be a crank.

It is the relative positions of these three points – the effort, the load and the fulcrum – that distinguishes the type or class of lever. There are three classes of lever 1st, 2nd and 3rd class. Other examples of first class levers are pliers, scissors, a crow bar, a claw hammer, a see-saw and a weighing balance.

Some examples of the wheel and axle include a door knob, a screwdriver, an egg beater, a water wheel, the steering wheel of an automobile, and the crank used to raise a bucket of water from a well. When the wheel in a wheel and axle machine is turned, so is the axle, and vice versa.

Clocks: Clocks use an axle and a wheel to tell time, but grandfather clocks also use levers, pulleys, wedges, screws, axles and wheels as a complex machine.

Pizza Cutter When the force is applied to the wheel, it tends to move. Thereby, creating pressure on the axle. Hence, a pizza cutter is a classic example of a wheel and axle simple machine.

A Ferris wheel is an example of a machine called a wheel and axle.

The pizza cutter was used as an example of a tool where the fulcrum is considered to be the wrist or elbow of the user. Therefore, it is a third class lever.

Spoon is Class 1 lever. Definition of Lever: a rigid bar resting on a pivot, used to move a heavy or firmly fixed load with one end when pressure is applied to the other.
