"Механические" refers to mechanical systems or devices that operate based on physical principles and forces. These systems often involve components like gears, levers, and pulleys, which work together to perform tasks. Mechanical engineering is the field that focuses on designing and analyzing such systems, ensuring they function efficiently and reliably. In everyday life, we encounter many механические devices, such as watches, cars, and machines used in factories. These devices convert energy into motion or perform specific functions, making our lives easier and more productive. Understanding механические systems is essential for advancements in technology and engineering.
