Actuators are used for various purposes, their construction and output can be mapped according to your needs. To give you an example, Actuators in sports cars used for traction and down force. Actuator powered spoilers come into effect when the car crosses 150kmph. Spoilers add up to the stability of the car at high speeds. The car can easily cruise on straights by having the right type of airflow. Cornering is easy since there is enough of down force available for the car to glide. It can attempt the car at a given a speed and increase when it hits the apex. Laws of physics applied in functioning of the car are brought to great use.
Actuators are used in lift tables for car repairs. The car is loaded on the lift system that is raised according to the requirements. Electricity is used in functioning of these lifts, it powers the actuator system. The car along with its weight is lifted for repairs and maintenance purposes.
