Final answer:
Cars and heavy machinery use mechanical, hydraulic, electronic, and computer controls collectively to operate. Hydraulic systems are applied in many areas, including vehicle brakes and heavy equipment.
Step-by-step explanation:
The component that uses mechanical, hydraulic, electronic, and computer controls—all working together to move it down the road—is typically found in modern vehicles, such as cars and heavy machinery like backhoes. These machines rely on complex systems that include hydraulic and mechanical lever systems to move and operate various parts. For example, hydraulic systems can be seen in power brakes, bulldozers, and even the movement of the legs of a spider, indicating the broad application of this technology.
Mechanical engineers design and analyze these systems for effectiveness and efficiency.In car factories, assembly lines facilitate the construction of cars, with conveyor belts moving the car past different assembly stations where different components, such as the body, doors, wheels, and steering wheel, are added in sequence. Mechanical engineers apply principles of physics to design and analyze these systems, ensuring they work effectively.
