Artificial tools make people's work easier and complete their work in a short time. People have created a lot of tools or machines for this purpose. The most famous of them is the Axe, The inclined plane, the wheel, the lever, the pulley, the screw, and the wedge. The last three instruments are combinations of the first three instruments.
Ordinary machines are devices with no, or very few, moving parts that make work easier. There are so many complex tools today. Since the Work is defined as the force acting on the object in the direction of motion.
The machine simplifies the work by performing one or more of the following functions that are:
The wheel is a round component that is designed to rotate on an axial bearing. The first wheels were not used for transportation. The wheel can be considered the most important invention of mankind. The utility of which is still used in many areas of our daily life. Thus, the wheels brought the mobility of our daily lives. The wheel is everywhere on all our cars, trains, airplanes, cars, wagons and most factory and agricultural machines.
The Axe has many variants. An Axe is a cutting tool consisting of a heavy edged head attached to a handle. It is especially used for cutting trees, chopping and splitting wood. It consists of a blade of heavy metal that is sharp at one end and is attached by the other edge to the end of the long handle.
Most modern axes have steel heads and wooden handles. Modern axes specialize in use, size, and shape. Initially, the axes were tools made of stone, called manual axles, which were used without pens. The Axe has two main components: the head and the upper part.
An inclined plane, also known as a ramp. It is a flat support surface inclined at an angle, with one end higher than the other. The inclined plane is a very old kind of simple machine. This allows you to use less force to move the object. This makes it easier to move objects to higher or lower surfaces.
In physics, an inclined surface is called an inclined plane. Wedge is a special kind of inclined plane. It is a triangular object with a smooth and even surface.
A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge. A lever is one of the most common tools we use to help us lift things beyond our strength limit. A lever is consisting of a bar that pivots on a fixed support. You can find them everywhere.
Good examples of levers include the seesaw, crowbar, fishing-line, oars, wheelbarrows and the garden shovel It is used to transmit torque. A force applied by pushing down on one end of the lever results in a force pushing up at the other end. The class of lever depends on the location of the load, force, and fulcrum.
A screw is a type of fastener, sometimes similar to a bolt. It is usually made up of metal. There are many types of screws, some of them are wooden screws, sheet metal screws, machine screws, etc. The screw is a mechanism that converts rotational motion into linear motion and torque.
This is one of the most commonly used mechanical devices around the world. The most commonly used screws are to hold objects together, for example, wood and position objects.
