Simple machines are the most fundamental and elementary components of mechanical systems. They represent the earliest human innovations in using physical tools to manipulate the environment. From the very beginning of human history, the ability to create and use tools, control fire, and develop language set humans apart from other animals. Simple machines reflect the ingenuity of early humans in applying mechanical principles to make work easier and more efficient. These devices, such as levers, pulleys, inclined planes, wedges, wheels, and axles, form the foundation of Newtonian mechanics and are essential in understanding how forces interact in the physical world. Their study not only reveals the basic laws of motion but also highlights the evolution of human technology and scientific thought over time.
