Mechanical systems are assemblies of interconnected components that work together to perform a specific function. These systems can include simple machines like levers and pulleys, as well as more complex arrangements like engines and robots. They rely on the principles of physics, particularly mechanics, to convert energy into motion or force. In everyday life, mechanical systems are found in various applications, from household appliances like washing machines to vehicles such as cars and airplanes. Understanding these systems helps engineers design more efficient machines and improve existing technologies, contributing to advancements in fields like automotive engineering and aerospace.
