Mechanical and electrical systems are essential components in various industries, including manufacturing, construction, and transportation. Mechanical systems involve the design and operation of machines and structures, focusing on moving parts, forces, and energy. Examples include engines, gears, and HVAC systems. Electrical systems, on the other hand, deal with the generation, distribution, and use of electrical energy. This includes wiring, circuits, and devices like motors and transformers. Together, mechanical and electrical systems work in harmony to power and control machinery, ensuring efficient operation in everyday applications.
